[0035] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0036] Based on the foregoing, it can be seen that in order to improve the user experience of using online services, the technical solution proposed in the embodiment of the present application can render a spatial effect diagram more dynamically to enhance the user experience.

[0037] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0038] Figure 1A The schematic diagram of the structure of a scene rendering system provided by an exemplary embodiment of the present application is as follows. Figure 1A As shown, the system 100 may include: a first device 101 and a second device 102 .

[0039] Among them, the first device 101 can be a device with certain computing capabilities, which can realize the function of sending data to the second device 102. The basic structure of the first device 101 may include: at least one processor. The number of processors may depend on the configuration and type of the device with certain computing capabilities. The device with certain computing capabilities may also include a memory, which may be volatile, such as RAM, or non-volatile, such as read-only memory (ROM), flash memory, etc., or may include both types at the same time. The memory usually stores an operating system (OS), one or more application programs, and may also store program data, etc. In addition to the processing unit and the memory, the device with certain computing capabilities also includes some basic configurations, such as a network card chip, an IO bus, a display component, and some peripheral devices, etc. Optionally, some peripheral devices may include, for example, a keyboard, an input pen, etc. Other peripheral devices are well known in the art and will not be described in detail here. Optionally, the first device 101 may be an intelligent terminal, such as a mobile phone, a desktop computer, a notebook, a tablet computer, etc.

[0040] The second device 102 refers to a device that can provide computing and processing services in a network virtual environment, and can refer to a device that uses the network to render a spatial scene. In physical implementation, the second device 102 can be anything that can provide computing services, respond to service requests, and return rendering results, such as a cloud server, cloud host, virtual center, conventional server, etc. The second device 102 mainly includes a processor, a hard disk, a memory, a system bus, etc., which is similar to a general computer architecture.

[0041] In an embodiment of the present application, the first device 101 may send a rendering request to the second device 102 in response to a user display instruction. The request may carry an identifier of the spatial scene to be rendered. The second device 102 receives the request and determines the corresponding spatial scene to be rendered. The second device 102 determines the emitted light of the spatial scene for the current spatial scene to be rendered; determines the light path formed by the emitted light in the spatial scene with the object as the starting point based on the object where the emitted light first intersects in the spatial scene; determines the indirect lighting result of the emitted light relative to the object based on the light path and the material information of the object corresponding to the light path in the spatial scene, renders the spatial scene based on the indirect lighting result corresponding to the spatial scene, and displays the rendering result.

[0042] In addition, the second device 102 can also determine the direct lighting result generated by the light source in the spatial scene when the emitted light is directly returned from the object based on the material information of the object; obtain the global lighting result based on the direct lighting result and the indirect lighting result, and render the spatial scene based on the global lighting result corresponding to the spatial scene to obtain the rendering result, and then send the rendering result to the first device 101 for display.

[0043] In addition, since the indirect illumination result will generate noise after the second device 102 obtains the indirect illumination result, the second device 102 can reduce the noise of the indirect illumination result according to the preset noise reduction algorithm to determine the global illumination result. After noise reduction, the indirect illumination result can also be multiplied by the material information of the first object to obtain a corrected indirect illumination result to determine the global illumination result.

[0044] In order to enhance the shadow effect, the shadow results between objects in the space scene can also be determined to determine the final global illumination result.

[0045] In the interior design application scenario of the embodiment of the present application, Figure 1BAs shown, a user, such as a designer, can select a corresponding indoor space scene through a first device 101, such as a computer or a mobile phone, and send a viewing instruction to the mobile phone. In response to the instruction, the mobile phone can send a rendering request to a second device 102, such as a cloud server. The request can carry an identifier of the indoor space scene. After receiving the request, the cloud server determines the corresponding indoor space scene according to the identifier. After determining the scene, the cloud server emits light into the scene 103 through a virtual camera 106 in the scene 103. A two-dimensional blank image 107 is set in front of the virtual camera 106, and light is emitted into the scene 103 according to the pixels therein. Take a pixel as an example for explanation: after emitting light 105 into the scene 103 through a pixel, it hits the first object in the scene 103, such as a table 108 in the indoor space scene, and the cloud server obtains the material information of the table. Based on the material information, it is determined how the emitted light propagates after hitting the table, such as diffuse reflection and highlight reflection, and the light path of the diffuse reflection and highlight reflection is determined at the same time. According to the recursive method of the light path and the illumination model, the indirect illumination result of the diffuse reflection and the indirect illumination result of the highlight reflection are determined. The cloud server can also determine the direct illumination result for the illumination effect produced by the light source in the scene directly shining on the table based on the illumination model and the material information of the table. The direct illumination result and the indirect illumination result are added to obtain the global illumination result. The cloud server can determine the color corresponding to the pixel according to the global illumination result and perform color drawing. Finally, all pixels have colors. The cloud service sends the rendering result to the user's mobile phone, and the mobile phone can directly display it according to the rendering result, and can display the rendering result of the scene 103, that is, the image 104 of the scene 103.

[0046] In addition, in order to improve the rendering effect, after determining the indirect lighting results, the cloud server performs noise reduction on these two results according to different indirect lighting results, such as the highlight reflection indirect lighting results and the diffuse reflection indirect lighting results. After noise reduction, each indirect lighting result is multiplied by the material information of the table to obtain the corrected indirect lighting result. The cloud server can add the corrected indirect lighting result to the direct lighting result. At the same time, the cloud server can also determine the shadow results between objects in the indoor space scene, and add them to the corrected indirect lighting results and direct lighting results to obtain the global lighting result, thereby determining the color of each pixel, performing color drawing, and sending the final rendering result to the user's mobile phone for display.

[0047] It should be noted that the user can also modify the indoor space scene, re-render the modified scene, and display it to the user. The user can also move in the scene, so that the virtual camera 106 moves accordingly, and re-render the scene with the new perspective of the virtual camera 106 and display it to the user.

[0048] In addition to being applied to the above scenarios, it can also be applied to online shopping scenarios. Among them, the user can be a buyer and watch the scene in a specific online sales scenario, such as an indoor furniture sales space scenario. At this time, the rendering result can be provided to the user and displayed according to the above method. The specific rendering method will not be repeated here.

[0049] In the above embodiment, the above device can be connected to the network, and the network connection can be a wireless connection. If it is a communication connection, the network standard of the mobile network can be any one of 2G (GSM), 2.5G (GPRS), 3G (WCDMA, TD-SCDMA, CDMA2000, UTMS), 4G (LTE), 4G+ (LTE+), WiMax, 5G, etc.

[0050] The rendering of the scene is described in detail below in conjunction with the method embodiment.

[0051] Figure 2 The flowchart of a method for rendering a scene according to an exemplary embodiment of the present application is shown in FIG. The method 200 provided in the embodiment of the present application is executed by a computing device, such as a cloud server. The method 200 includes the following steps:

[0052] 201: For the current spatial scene to be rendered, determine the emission light of the spatial scene.

[0053] 202: According to the object in the space scene where the emitted light first intersects, determine a light path formed by the emitted light in the space scene with the object as a starting point.

[0054] 203: Determine the indirect lighting result of the emitted light relative to the object according to the light path and the material information of the object corresponding to the light path in the space scene.

[0055] 204: Render the spatial scene based on the indirect lighting result corresponding to the spatial scene, and display the rendering result.

[0056] It should be noted that the execution subject may also be a smart terminal, and the method 200 may be executed if the performance of the smart terminal can support it.

[0057] The following is a detailed description of the above steps:

[0058] 201: For the current spatial scene to be rendered, determine the emission light of the spatial scene.

[0059] Rendering refers to the process of drawing 3D (3-dimension, also known as virtual space) data stored in text binary or other forms into an image.

[0060] The space scene refers to a virtual space, such as an indoor virtual space, a store virtual space, etc. The space scene may have light sources and objects. Different objects may be set according to different virtual spaces.

[0061] in, Figure 3 A space scene 300 is shown. The scene is an indoor space scene, i.e., an indoor virtual space. The scene 300 includes a lamp 301, a television 302, a table 303, and flowers 304. In addition, the scene 300 may also include walls and a floor, but these are not marked in the scene 300. At the same time, the scene 300 may also include a light source, which is not drawn or marked.

[0062] The method of obtaining the space scene may include:

[0063] A viewing request or a selection request is received, and the request may carry an identifier of a spatial scene, such as an ID, and the request is used to determine the spatial scene. Based on the identifier, a corresponding spatial scene may be selected or determined from a plurality of preset spatial scenes.

[0064] Alternatively, a modification request is received, the current spatial scene is modified, and the modified spatial scene is used as the spatial scene to be rendered.

[0065] For example, as described above, the cloud server receives a viewing request sent by the user's mobile phone. The user's mobile phone may be installed with an online interior design app (application). The user clicks on the app to display the design interface, and can select or view the designed interior space scenes. Based on the user's viewing operation or selection operation, the mobile phone responds to the operation and sends a request to the cloud server, carrying the ID of the space scene. The cloud server selects the corresponding space scene from multiple designed space scenes based on the ID. Alternatively, the user selects the corresponding apartment room from the cloud server and designs in the apartment room. The cloud server selects the furniture set in the room according to the user's selection request to make modifications in the room, and uses the modified room as the interior space scene to be rendered.

[0066] For a smart terminal, for example, a mobile phone or a computer can directly respond to the user's operation and directly select the corresponding spatial scene from the local of the smart terminal.

[0067] After the spatial scene is determined, the spatial scene may be rendered. The rendering process may be determined by tracing rays.

[0068] Specifically, for the current spatial scene to be rendered, determining the emission light of the spatial scene includes: determining the emission light of the spatial scene through a virtual camera.

[0069] The virtual camera refers to a virtual device that simulates the user's eye view. The virtual camera can be set in the space scene or outside the space scene, and can also be moved in the space scene through the user's operation. The virtual camera can have a certain viewing angle range. The viewing angle range can be determined by a plane in the virtual camera. The plane can be used as the user's screen image, which can also be called a video screen.

[0070] For example, as described above, the cloud server may determine the emitted light by emitting light from the virtual camera to the indoor space scene, that is, simulating light, in accordance with the ray tracing method.

[0071] It should be noted that, in addition to the virtual camera, other virtual devices that can realize the function of the virtual camera can be used, or the cloud server can directly simulate the virtual camera and directly send virtual light to the spatial scene.

[0072] In addition, in order to better render the spatial scene, a plane graphic can be set in front of the virtual camera as the final user screen image.

[0073] Specifically, the method 200 also includes: a two-dimensional image is set in front of the virtual camera; wherein, determining the emitted light of the spatial scene includes: emitting virtual light to pixels in the two-dimensional image through the virtual camera, so that the emitted virtual light passes through the pixel into the spatial scene, thereby determining the global illumination result corresponding to the pixel.

[0074] The two-dimensional image may be blank in color.

[0075] in, Figure 4A space scene 400 with a virtual camera is shown. Virtual light can be directly emitted into the space scene 400 through a virtual camera 401. The emitted virtual light is emitted at a certain light angle. At the same time, a two-dimensional blank image 402, which is also a video screen, can be set in front of the virtual camera 401. The image 402 has a plurality of pixels 403. For each pixel, the virtual camera 403 emits a virtual light to the pixel at a certain emission angle, so that the light passes through the image 402 and enters the space scene 400. Of course, a point in each pixel can also be randomly selected as a reference, and the virtual camera 403 emits light to the randomly selected point.

[0076] It should be noted that, for each pixel in the image 402 , the center point of each pixel can be used as a reference, and the virtual camera 403 can emit virtual light to the center point of the pixel, thereby determining the emission angle and emitting virtual light to the spatial scene 400 .

[0077] In addition, for smart terminals, the execution steps are similar to those of the cloud server, so they will not be repeated here.

[0078] 202: According to the object in the space scene where the emitted light first intersects, determine a light path formed by the emitted light in the space scene with the object as a starting point.

[0079] Among them, the ray path meets the conditions of rendering time.

[0080] A light path refers to a light path composed of light rays, which can be formed when light rays propagate in a spatial scene. A light path can be related to the object hit by the light rays. For example, when light rays hit an object, they can be reflected or refracted according to the material information of the object, thus forming a light path.

[0081] In the embodiment of the present application, the emitted light is traced to determine whether the light path eventually reaches the light source in the virtual space. If it can reach the light source, the illumination result can be calculated by recursively calculating the light path.

[0082] However, since the light paths are very complex and there may be a large number of them, there may also be some invalid light paths. Therefore, when calculating the lighting results, a large amount of calculations will be generated, resulting in an increase in rendering time. Therefore, in an embodiment of the present application, the light path can be restricted to meet the rendering time conditions. For example, the length and number of light paths are restricted to meet certain thresholds. For example, the length of the light path can be the length of the path passing through two objects. Alternatively, the light path is not traced for refraction inside the object to reduce the number of light paths.

[0083] It should also be noted that during the propagation process, light will attenuate after multiple refractions or reflections. Therefore, when the light path is too long, the light path can be shortened to determine the lighting result.

[0084] At the same time, you can also focus on the lighting results generated by reflected light, such as diffuse reflection and specular reflection, and ignore the lighting results of refraction. Of course, considering the lighting results of refraction can make the final lighting results more accurate. However, in order to accommodate rendering time, you can also ignore the lighting results of refraction according to your needs.

[0085] In addition, the object can be determined by: according to the position of each object in the current spatial scene, that is, the spatial coordinates, determining the object that the emitted light will hit for the first time, that is, the first object that the emitted light intersects with in the spatial scene. It is worth noting that the first object here is not an identification of the object, but refers to the first object in the spatial scene that intersects with the emitted light. The object can be any object that intersects with the light for the first time and is not restricted by the object identification. In addition, a beam of directional emitted light only directly intersects with one object in the spatial scene, and can intersect with other objects indirectly, that is, through reflection, etc.

[0086] It should be noted that, since the emitted light is emitted at a certain emission angle, the emitted light can be determined, and its propagation path (it can also be the light path before hitting the object) is also determined. At the same time, each object in the spatial scene has specific spatial coordinates, and for the sake of simplicity, each object can be represented by a triangle, thereby evolving into determining the first triangle that the emitted light will hit, and determining the triangle with the shortest propagation path, which can be reached, by determining the propagation path of the emitted light. And determine the identification of the triangle, such as the number. In addition, the coordinates of the hitting point of the triangle can also be determined based on the propagation path, that is, which point of the triangle is hit is also the coordinates of the hitting point of the object.

[0087] After the object is determined, the light path can be determined based on the material information of the object.

[0088] Specifically, determining a light path formed by emitting light from the object as a starting point in the space scene includes: determining the light path according to material information of the object.

[0089] Among them, material information refers to the visual properties of the object surface, which can include the object's diffuse color, highlight color, roughness, etc. This material information will be used to calculate the lighting results.

[0090] The acquisition of material information may include: since each object in the space scene can be pre-stored in the model library. And the material of each object can also be stored in a pre-stored storage area and marked with its identification, such as a number. According to the foregoing, after determining the number of the object, the corresponding material information can be obtained from the pre-stored storage area according to the number, and the material information is stored in the map.

[0091] For example, according to the above, the first object that the emitted light hits in the indoor space scene is a table. After determining the material information of the table, the cloud server can perform diffuse reflection, specular reflection, and refraction according to the material information. For example, after diffuse reflection, the emitted light propagates into the air without touching any object or returning to the light source, thus forming a light path.

[0092] It should be noted that, since this light path does not intersect with any object, the illumination result corresponding to the light path is 0.

[0093] In addition, the light path may continue to intersect with other objects through diffuse reflection, and then other light paths may be generated according to the material information of subsequent objects until the light returns to the light source.

[0094] in, Figure 5 A schematic diagram of the light path is shown. Figure 5 In the figure, the virtual camera 401 emits a ray 501 to one of the pixels 403 in the image 402. The ray 501 first hits the object table 303. According to the material information of the table 303, diffuse reflection is performed to generate a ray path 502, and then the ray hits the wall to generate a ray path 503, and then the ray hits the lamp 301 to generate a ray path 504, and then returns to the light source 505. Among them, the ray paths 502-504 constitute the ray path generated on the table.

[0095] Correspondingly, for other reflections, such as specular reflection and refraction, corresponding light paths will also be generated, thereby determining these different light paths.

[0096] Specifically, determining the light path includes: determining different light types corresponding to different light paths generated on the object according to material information; and determining corresponding light paths for different light types.

[0097] Among them, different light types refer to diffuse reflection, refraction, and specular reflection, etc. Therefore, different relationship paths are determined according to different types.

[0098] The specific determination method is similar to that described above and will not be repeated here.

[0099] Specifically, for different light types, the corresponding light paths are determined with the object as the starting point, including: for the light corresponding to the light type, the light paths generated by the light passing through other objects in the space scene are determined as the corresponding light paths. The number of other objects is less than the corresponding threshold in the rendering time condition.

[0100] This has been explained in detail in the previous article, so I will not repeat it here. I will just explain that in the process of reflection or refraction of the object, in order to meet the rendering time requirements, if the light path is too long due to passing through multiple objects, and because the light will attenuate, the subsequent light path can be ignored.

[0101] Among them, Figure 5 As shown, since the light paths 502-504 pass through objects such as tables, walls, and lamps, the light paths are too long, so the other objects can be set to 1, that is, the light paths after passing through the wall can be ignored. Figure 5 The light paths in are light path 502 and light path 503, returning to the light source.

[0102] In addition, the refraction inside the object can be ignored, and only the light paths generated by subsequent reflected light can be considered, thereby reducing the number of light paths, reducing the amount of calculation, and saving rendering time.

[0103] In addition, for diffuse reflection, since diffuse reflection is the reflection of light projected on a rough surface in all directions, that is, random reflection, multiple different light paths can be generated. In order to better determine the light path of diffuse reflection, a random algorithm can be used to determine it.

[0104] Specifically, when the light type is diffuse reflection, determining the corresponding light path includes: determining the diffuse reflection direction range of the diffuse reflection light on the object according to the emission direction and material information; selecting the diffuse reflection direction within the diffuse reflection direction range according to a preset random algorithm; and determining the light path according to the diffuse reflection direction. The number of diffuse reflection directions is less than the corresponding threshold in the rendering time condition.

[0105] Among them, random algorithms refer to algorithms that use probability and statistical methods to make random choices for the next calculation step during their execution. Random algorithms have certain advantages and randomness. For example, the Sobol sequence random algorithm.

[0106] For example, according to the previous description, the emitted light first hits the object, the table. Due to the material information of the table, when the table is a purely diffuse reflective object, the emitted light will be randomly reflected on the surface of the table, and the reflection direction range is the normal hemisphere of the hit point. The cloud server can use the sobol sequence random algorithm to let the emitted light randomly reflect in a certain direction of the normal hemisphere, generate multiple corresponding light paths, and iteratively calculate the lighting results until the maximum recursive layer is reached, and the final lighting results are returned. Among them, the maximum recursive layer refers to the number of recursions, which is similar to the number of other objects passed through as mentioned above. Therefore, the maximum recursive layer can also be limited, such as less than a certain threshold, to meet the needs of rendering time.

[0107] In addition, since diffuse reflection is performed within the range of reflection directions, the reflection within this range can also be limited, such as limiting the number of reflections. A random algorithm can be used to evenly diffuse reflection within this range under the condition of limiting the number, so as to reduce rendering time while maintaining rendering effects.

[0108] in, Figure 6 A schematic diagram of multiple light paths is shown. Figure 6 In the example, the emitted light 501 may hit the table 303 and generate diffuse reflection. Figure 6 The two diffuse reflection rays are used as an example: it should be understood that in practice, there may be multiple diffuse reflection rays within the preset direction range. Figure 6 In the figure, light 501 is diffusely reflected by table 303, generating light path 502 and light path 601, and light path 601 is then passed through the wall to generate light path 602. Thus, the indirect lighting result can be determined based on the light paths generated by these two diffuse reflections.

[0109] It should be noted that, in order to generate a high-quality spatial scene graph, the time required is generally between several minutes and tens of hours, which wastes high resource costs and time costs, and reduces the user experience. However, since the embodiment of the present application determines the light path according to the rendering time condition, it can flexibly grasp the light path, such as the number and length of the light path, while flexibly grasping the rendering time. Especially when the rendering time requirement is high, if the rendering time is required to be shorter, the light path can be determined accordingly, such as reducing the number and length of the light path. Thereby, the time required for the determination process of the indirect lighting result is reduced, thereby reducing the rendering time, speeding up the display of the image of the spatial scene, improving the rendering efficiency and improving the user experience.

[0110] For smart terminals, the execution steps are similar to those of cloud servers, so they will not be repeated here.

[0111] 203: Determine the indirect lighting result of the emitted light relative to the object according to the light path and the material information of the object corresponding to the light path in the space scene.

[0112] Among them, indirect lighting refers to the lighting effect produced by the light generated by the light source after being reflected or refracted on other objects, illuminating the object. The corresponding light brightness is the lighting result.

[0113] After determining the light path, the indirect lighting effect can be determined based on the material information of the objects that the light path passes through and the lighting model. Figure 6 As shown, the light paths 502 - 504 pass through the object table 303 , the wall and the lamp 301 .

[0114] In addition, the illumination model may include a Phong illumination model, a Lambert model, etc., which are used to calculate the illumination result.

[0115] Specifically, based on the light path and the material information of the object corresponding to the light path in the spatial scene, the indirect lighting result of the emitted light relative to the object is determined, including: for other objects passed by each light path, according to the recursive method of the light path, determining the indirect lighting result corresponding to each other object and the indirect lighting result of the object.

[0116] For example, according to the above, if Figure 6 As shown, the light path 502-504 is used as an example for explanation: it should be understood that here, only for the sake of clarity, a complete light path is used for explanation. In the embodiment of the present application, in order to meet the requirements of rendering time, a maximum recursive layer will be set, or the length of the light path will be limited, so the light path may not be a complete light path. The recursive method of the incomplete light path is the same as the recursive method of the complete light path, and it will not be repeated. Among them, for the light paths 502-504, according to the recursive method, the indirect lighting result of the light path 504 from the light source 505 to the lamp 301 is first determined based on the material information of the lamp 301 and the lighting model, and used as the indirect lighting result of the hitting point of the lamp 301. By analogy, the indirect lighting result corresponding to the light path 503 is determined based on the indirect lighting result of the hitting point of the lamp 301, and used as the indirect lighting result of the hitting point of the wall. Finally, the indirect lighting result of the hitting point of the table 301 is determined.

[0117] It should be noted that when determining the indirect lighting result for light paths 502-504, it can be assumed that no other light paths are generated. In actual situations, other light paths may be generated, so the indirect lighting result for the hitting point of an object may be determined by the indirect lighting results corresponding to multiple light paths. For example, for table 303, its indirect lighting result is determined by the sum of the indirect lighting results corresponding to light paths 502-504 and light paths 601-602. The indirect lighting results for other objects are calculated in the same way.

[0118] After calculating the indirect illumination results corresponding to each light path corresponding to the table 301, they are added to obtain the final result. In addition, in order to improve the accuracy of the indirect illumination results, 5 to 10 sampling points may be required for each pixel to sample the indirect illumination results and add them up, such as determining multiple times that different light paths will be generated after hitting the first object, and determining the sum of the corresponding indirect illumination results.

[0119] After determining the indirect illumination result, the direct illumination result can be determined, thereby determining the global illumination result.

[0120] 204: Render the spatial scene based on the indirect lighting result corresponding to the spatial scene, and display the rendering result.

[0121] Specifically, the method 200 also includes: determining, based on the material information of the object, a direct illumination result generated by emitting light directly from the object back to a light source in the spatial scene; obtaining a global illumination result based on the direct illumination result and the indirect illumination result, so as to render and display the spatial scene based on the global illumination result corresponding to the spatial scene.

[0122] Among them, direct illumination refers to the illumination effect produced by the light generated by the light source directly illuminating the object, and its light brightness is the direct illumination result. The sum of the direct illumination result and the indirect illumination result is the global illumination result.

[0123] Among them, the direct lighting result can be determined according to the rasterization method. After the direct lighting result is determined, it is added to the indirect lighting result to obtain the global lighting result and determine the corresponding color for rendering and display.

[0124] In the rasterization method, the space scene and the objects therein can be pixelated, and the direct lighting result can be determined by the material information of the object. Since the rasterization method can speed up the determination time of the direct lighting result, the overall rendering time can be accelerated.

[0125] It should be noted that the method for determining the global illumination result can also be determined based on the global illumination method of voxels. Among them, the global illumination method of voxels is to divide the spatial scene into 3D voxels when the spatial scene is initialized, and then treat each voxel as an object to receive illumination, calculate the illumination result, and store the illumination result in 3D data, such as 3D textures. Later, in the process of rendering the spatial scene, the calculated voxel illumination result is used as the light source to calculate the illumination of the object. However, the illumination result after voxelization of the spatial scene is not accurate enough, and its accuracy is very limited. And because voxels reflect light, light leakage problems will occur at objects such as walls. At the same time, due to the large number of voxels, the illumination result after multiple reflections is very large in calculation, and the effect is not ideal, which will consume time and resources.

[0126] In addition, as we know from the previous article, since the indirect lighting result is determined by a random algorithm, the indirect lighting result determined by the random algorithm will bring noise. Therefore, it is usually adopted to emit many rays to a pixel in the offline rendering method, and obtain accurate lighting results by superimposing sampling. However, the result of doing so is that the rendering time becomes very long. Therefore, in order to reduce noise and improve the rendering effect, the indirect lighting result can be denoised. The purpose of denoising is to obtain an indirect lighting result with less noise or no noise, while retaining the lighting details of the object as much as possible.

[0127] Specifically, the method 200 further includes: performing noise reduction on the indirect illumination result according to a preset noise reduction algorithm to determine the global illumination result.

[0128] Among them, the preset noise reduction algorithm refers to an algorithm for removing noise from the indirect lighting results. The algorithm will consider the position of the object, the normal of the object, and the indirect lighting results, etc., and retain the lighting details of the object to the greatest extent. The preset algorithm can be to use the average indirect lighting result of the pixels in the preset range as the indirect lighting result of the pixels in the range to perform noise reduction. However, the selection of the preset range needs to consider factors such as the position, normal and indirect lighting results of the object. For example, for the same table, the indirect lighting results of the table top and the table legs are quite different due to different positions, so they cannot be used as the same range. The indirect lighting results of the different corners of the tabletop are also quite different due to position problems, and cannot be used as the same range. Therefore, the pixels in the same preset range must belong to the same object and belong to the pixels within the same position threshold range, and the difference in their indirect lighting results is within a certain threshold range, so the average indirect lighting result in the preset range can be determined for noise reduction. For example, corresponding pixels smaller than the average indirect illumination result are regarded as noise points, and their indirect illumination results are modified to be the average indirect illumination result, thereby performing noise reduction.

[0129] For example, as mentioned above, the cloud server inputs the indirect illumination result into the preset algorithm to determine the indirect illumination result after noise reduction, so that the global illumination result can be determined more accurately.

[0130] In addition, in order to better perform noise reduction, layered noise reduction can be performed on the indirect lighting results of the object.

[0131] Specifically, the method 200 also includes: determining different types of light corresponding to different light paths generated on the object based on the material information of the object; determining different indirect lighting results corresponding to different types of light of the object based on a recursive method of the light paths; denoising different indirect lighting results respectively according to a preset denoising algorithm to obtain different indirect lighting results after denoising; obtaining a denoised indirect lighting result based on the different indirect lighting results after denoising to determine a global lighting result.

[0132] For example, as can be seen from the foregoing, the cloud server can store the diffuse reflection indirect lighting results, the refraction indirect lighting results, and the specular reflection indirect lighting results of the object, such as a table, respectively. Then, these indirect lighting results are denoised by a preset denoising algorithm to obtain the denoised indirect lighting results.

[0133] in, Figure 7 A spatial scene graph with noise. In order to account for the noise, the Figure 7 It is already an image after imaging, that is, a two-dimensional image. Figure 7 Many noise points can be seen in Figure 7 The black dots in the.

[0134] in, Figure 8 The spatial scene diagram after noise reduction is shown in Figure 1. Figure 8 is the image after imaging, that is, a two-dimensional image. Figure 8 You can see that the noise has been removed.

[0135] After denoising, in order to improve the rendering effect, you can continue to correct the indirect lighting results.

[0136] Specifically, the method 200 further includes: obtaining a corrected indirect illumination result based on the denoised indirect illumination result and the material information of the object; and determining a global illumination result based on the corrected indirect illumination result.

[0137] Since the material information is accurate and does not contain noise, multiplying the indirect lighting result by the material information can retain some of the object's details. The indirect lighting result here can be the sum of all indirect lighting results or the layered indirect lighting result. For the layered indirect lighting result, it is necessary to perform lighting synthesis on the total indirect lighting result. Then the global lighting result is finally determined.

[0138] In order to make the rendering effect more realistic, the shadow results of indirect lighting can also be used to increase the lighting details of the object.

[0139] Specifically, the method 200 also includes: determining, for the object, a shadow result between objects in the spatial scene, wherein the shadow result is generated based on indirect illumination of the objects in the spatial scene; and determining a global illumination result based on the shadow result, the indirect illumination result and the direct illumination result.

[0140] For example, according to the above description, the cloud server determines the shadow result according to the ambient light occlusion algorithm. This algorithm belongs to the prior art and will not be described here. After the shadow result is determined, the shadow result, all indirect lighting results and direct lighting results are synthesized to obtain the global lighting result.

[0141] It should be noted that for smart terminals, the execution steps are similar to those of cloud servers, and will not be repeated here.

[0142] In addition, when the user directly views the preset spatial scene when initializing the spatial scene on the cloud server or smart terminal, the corresponding spatial scene can be directly obtained from the preset storage spatial scene and rendered according to the corresponding preset global illumination result.

[0143] It should be noted that, after the cloud server determines the final rendering result, it returns the rendering result to the user's smart terminal for display. If the smart terminal directly obtains the rendering result, it can be displayed directly.

[0144] Specifically, the method 200 also includes: obtaining corresponding global illumination results based on different preset spatial scenes; based on the user's selection operation, selecting a corresponding preset spatial scene from different preset spatial scenes, and determining the corresponding global illumination result based on the selected spatial scene; based on the global illumination result, rendering and displaying the selected spatial scene.

[0145] For example, as described above, the cloud server receives a request sent by the user's mobile phone. The request is based on the selection interface provided by the user on the mobile phone. The interface displays multiple preset spatial scenes. The user selects one of the preset spatial scenes. The mobile phone responds to the instruction and sends a selection request. After receiving the request, the cloud server can determine the corresponding spatial scene according to the scene ID carried in the request, and then obtain the corresponding global illumination result, render it, and return the rendering result to the user's mobile phone for display.

[0146] It should be noted that the preset global illumination result can be determined by the above method or by the baked global illumination method. After the illumination result is determined by the baked global illumination method, the illumination result of the entire spatial scene is pre-calculated and stored in the texture. When rendering the spatial scene, the illumination result is obtained directly from the texture. However, the baked global illumination method only supports static spatial scenes and is not suitable for dynamic spatial scenes. Secondly, the illumination results saved in the texture are missing and the accuracy is insufficient. In addition, the texture usage is large, which has relatively high requirements for storage space and will also increase the scene loading time.

[0147] For smart terminals, the execution method is similar to that of cloud servers, so it will not be repeated here. It is only explained that smart terminals can directly respond to user instructions for rendering and display.

[0148] In order to improve the user experience, the embodiments of the present application may also support the user to dynamically modify the spatial scene, thereby dynamically rendering the modified spatial scene.

[0149] Specifically, the method 200 also includes: after displaying the rendering result, based on the user's modification operation, modifying the objects in the spatial scene and obtaining a new spatial scene; for the new spatial scene, executing the step of determining the emission light of the spatial scene for rendering and display.

[0150] For example, according to the foregoing, after the user's mobile phone displays the indoor space scene, the user can modify the space scene. For example, while displaying the space scene, the mobile phone can also display objects that can be modified, such as different furniture. The furniture can be displayed by type, such as beds, televisions, tables, etc. Each type can have multiple choices. The user can choose a table-shaped table from the table type and replace the table in the current indoor space scene. At this time, the mobile phone responds to the modification operation and sends a modification request to the cloud server. The request can carry the ID of the space scene and the IDs of the replacement table and the replaced table, and modify the space scene to obtain the modified space scene. The modified space scene is used as the space scene to be rendered, and is rendered again according to the method described above, and the rendering result is returned to the user's mobile phone for display.

[0151] For smart terminals, the execution method is similar to that of cloud servers, so it will not be repeated here. It is only explained that smart terminals can directly respond to user instructions for rendering and display.

[0152] In order to better meet the needs of users, multiple rendering modes may be provided for users to choose from, and different rendering modes may have different rendering effects.

[0153] Specifically, the method 200 further includes: determining a corresponding rendering mode based on a user's rendering mode selection operation; and rendering the spatial scene according to the determined rendering mode.

[0154] The rendering method may include an offline rendering method, a rendering method provided by the method 200 , indirect illumination rendering, global illumination rendering without shadow effects, and the like.

[0155] For example, as described above, after the user selects a spatial scene, or before rendering the spatial scene, a prompt message can be sent to the user's mobile phone to prompt the user to select a rendering method. After the user selects the rendering method, the rendering is performed based on the rendering method, and the rendering result is displayed.

[0156] In addition, the user may be provided with a function of turning on or off the rendering mode, so that the user may flexibly control the rendering mode.

[0157] Specifically, the method further includes: based on the user's opening or closing operation on the current rendering mode, opening or closing the corresponding rendering mode; after closing the current rendering mode, selecting a rendering mode from other rendering modes to render the spatial scene.

[0158] Since the implementation method of providing the mode of turning on and off rendering is similar to that described above, it will not be described in detail here.

[0159] Based on the above similar inventive concept, Fig. 9 A schematic flow chart of a scene rendering method provided by another exemplary embodiment of the present application is shown. The method 900 provided by the embodiment of the present application can be executed by the above-mentioned server, such as Fig. 9 As shown, the method 900 includes the following steps:

[0160] 901: Based on the viewing operation, determine a corresponding indoor space scene to be rendered.

[0161] 902: For the current indoor space scene to be rendered, determine the emission light of the indoor space scene.

[0162] 903: According to the object in the indoor space scene where the emitted light first intersects, determine a light path formed by the emitted light in the indoor space scene with the object as a starting point.

[0163] 904: Determine an indirect lighting result of the emitted light relative to the object according to the light path and material information of an object corresponding to the light path in the indoor space scene.

[0164] 905: Render the indoor space scene based on the indirect lighting result corresponding to the indoor space scene, and display the rendering result.

[0165] Among them, the ray path meets the conditions of rendering time.

[0166] Since the specific implementation of steps 901-905 has been described in detail above, they will not be repeated here. It is only explained that the execution subject of method 900 can also be a smart terminal, such as a mobile phone, a desktop computer, a tablet computer, etc.

[0167] In addition, the 900 method also includes: generating a new indoor space scene based on the modification operation of the objects in the indoor space scene; and executing the step of determining the emission light of the indoor space scene for the new indoor space scene to render and display the new indoor space scene.

[0168] Since this has been explained in the previous article, I will not repeat it here.

[0169] In addition, the 900 method also includes: determining a corresponding preset indoor space scene based on a selection operation of a preset indoor space scene; determining a corresponding preset global illumination result according to the determined preset indoor space scene; and rendering and displaying the determined preset indoor space scene based on the preset global illumination result.

[0170] Since it has been explained in detail in the previous article, it will not be repeated here.

[0171] In addition, for the contents not described in detail in the method 900, reference may also be made to the various steps in the above method 200.

[0172] Based on the above similar inventive concept, Fig.10 A schematic flow chart of a scene rendering method provided by another exemplary embodiment of the present application is shown. The method 1000 provided by the embodiment of the present application can be executed by the above server, such as Fig.10 As shown, the method 1000 comprises the following steps:

[0173] 1001: Based on the viewing operation, determine a corresponding shopping space scene to be rendered.

[0174] 1002: For the shopping space scene currently to be rendered, determine the emission light of the shopping space scene.

[0175] 1003: According to the object in the shopping space scene where the emitted light first intersects, determine a light path formed by the emitted light in the shopping space scene with the object as a starting point.

[0176] 1004: Determine the indirect lighting result of the emitted light relative to the object according to the light path and the material information of the object corresponding to the light path in the shopping space scene.

[0177] 1005: Render the shopping space scene based on the indirect lighting result corresponding to the shopping space scene, and display the rendering result.

[0178] Among them, the ray path meets the conditions of rendering time.

[0179] Since the specific implementation of steps 1001-1005 has been elaborated in detail above, they will not be repeated here. Just to explain: the viewing operation in step 1001 can be a user viewing a preset shopping space scene on the interface provided by the smart terminal, or it can be a shopping space scene just designed by the user. Among them, the shopping space scene can be a space scene of an online store, or a purchase space scene for indoor furniture display, etc. In response to the viewing operation, the smart terminal can send a request to the cloud server to render and display the space scene. In the case where the execution subject is a smart terminal, the smart terminal can directly perform the rendering.

[0180] At this point, the user can be a designer or a buyer, etc.

[0181] In addition, the method 1000 further includes: based on the movement operation in the shopping space scene, moving the position of the virtual camera in the shopping space scene; based on the moved virtual camera, determining the emission light of the shopping space scene to render and display the shopping space scene.

[0182] For example, as described above, users can view various products in the spatial scene of the store. Users can move in the scene by touching the screen of their mobile phone. In response to the movement operation, a movement request can be sent to the cloud server, and the position of the virtual camera in the scene can be moved. And the current scene is re-rendered based on the position of the virtual camera. The specific rendering process has been explained above and will not be repeated here. In addition, when the execution subject is a smart terminal, the smart terminal directly responds to the operation, moves the virtual camera, and renders.

[0183] In addition, the method 1000 further includes: determining a new shopping space scene based on the scene switching operation; and determining the emission light of the new shopping space scene for the new shopping space scene, so as to render and display the new shopping space scene.

[0184] Since it has been described in detail above, it will not be repeated here. It is only explained that the switching operation can be to switch the shopping space scene among multiple preset shopping space scenes, and then render and display the shopping space scene after switching.

[0185] In addition, for the contents not described in detail in the method 1000 , reference can also be made to the various steps in the above method 200 .

[0186] Fig.11 A schematic diagram of the structural framework of a rendering device for a scene provided by an exemplary embodiment of the present application. The device 1100 can be applied to a server. The device 1100 includes: a transmitting module 1101, a determining module 1102, and a rendering module 1103; the functions of each module are described in detail below:

[0187] The emission module 1101 is used to determine the emission light of the space scene for the current space scene to be rendered.

[0188] The determination module 1102 is used to determine, based on an object in the space scene intersected by the emitted light for the first time, a light path formed by the emitted light in the space scene with the object as the starting point.

[0189] The determination module 1102 is used to determine the indirect illumination result of the emitted light relative to the object according to the light path and the material information of the object corresponding to the light path in the space scene.

[0190] The rendering module 1103 is used to render the spatial scene based on the indirect lighting result corresponding to the spatial scene, and display the rendering result.

[0191] Among them, the ray path meets the conditions of rendering time.

[0192] In addition, the rendering module 1103 is used to determine the direct lighting result generated by the light source in the spatial scene when the emitted light directly returns from the object according to the material information of the object; and obtain the global lighting result according to the direct lighting result and the indirect lighting result, so as to render and display the spatial scene based on the global lighting result corresponding to the spatial scene.

[0193] Specifically, the emission module 1101 is used to determine the emission light of the space scene through a virtual camera.

[0194] In addition, the device 1100 includes: a setting module, which is used to set a two-dimensional image in front of the virtual camera; wherein, the transmitting module 1101 is used to emit virtual light to pixels in the two-dimensional image through the virtual camera, so that the emitted virtual light passes through the pixel into the spatial scene, thereby determining the global illumination result corresponding to the pixel.

[0195] Specifically, the determination module 1102 is used to determine the light path according to the material information of the object.

[0196] Specifically, the determination module 1102 includes: a first determination unit, used to determine different light types corresponding to different light paths generated on the object according to material information; and a second determination unit, used to determine corresponding light paths for different light types.

[0197] Specifically, the second determining unit is used to determine, for the light corresponding to the light type, a light path generated by the light passing through other objects in the space scene with the object as a starting point, as the corresponding light path.

[0198] Among them, the number of other objects is less than the corresponding threshold in the rendering time condition.

[0199] Specifically, when the type of light is diffuse reflection, the second determination unit is used to determine the diffuse reflection direction range of the diffuse reflection light generated on the object according to the emission direction and material information; select the diffuse reflection direction within the diffuse reflection direction range according to a preset random algorithm; and determine the light path according to the diffuse reflection direction.

[0200] Here, the number of diffuse reflection directions is less than the corresponding threshold in the render time condition.

[0201] Specifically, the determination module 1102 is used to determine, for each object passed by each light path, the indirect illumination result corresponding to each other object and the indirect illumination result of the object according to a recursive method of the light path.

[0202] In addition, the device 1100 further includes: a noise reduction module, which is used to perform noise reduction on the indirect illumination result according to a preset noise reduction algorithm to determine the global illumination result.

[0203] In addition, the determination module 1102 is used to determine the different types of light corresponding to different light paths generated on the object based on the material information of the object; determine the different indirect lighting results corresponding to the different types of light of the object according to the recursive method of the light path; the denoising module is used to perform denoising on different indirect lighting results according to a preset denoising algorithm to obtain different indirect lighting results after denoising; the determination module 1102 is used to obtain the denoised indirect lighting result based on the different indirect lighting results after denoising to determine the global lighting result.
