Description

Technical Field

[0001] This application relates to the field of computer technology, and more specifically, to a method, apparatus, storage medium, and electronic device for rendering virtual natural landscapes. Background Technology

[0002] In virtual game scenes, rendering realistic natural landscapes (such as frost and snow) can enhance the realism and expressiveness of the scene. However, rendering realistic natural landscapes usually requires significant performance overhead. This is especially true when rendering virtual natural landscapes onto virtual vegetation surfaces, which demands substantial device performance.

[0003] In related technologies, the rendering effect of the natural landscape is usually achieved by modifying the background texture of the natural landscape to be rendered, and then manually adding a preset landscape texture to the area of ​​the natural landscape to be rendered in the background texture. However, this method has the drawbacks of being complex, labor-intensive, and having poor reusability, and it is difficult to control the rendering degree and rendering range of the area to be rendered.

[0004] There is currently no effective solution to the above problems.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art.

Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0024] The rendering of virtual natural landscapes (such as frost and snow) on the surface of virtual vegetation models is an important part of scene representation in realistic games. Because the trunks (especially the leaves) of virtual vegetation models heavily utilize inlaid transparent textures and often need to consider wind effects that interact with virtual characters, the rendering performance of virtual vegetation models is typically quite high. How to render virtual natural landscapes on virtual vegetation models despite their high rendering performance has become a significant challenge in the relevant technical field.

[0025] In one possible implementation of this application, the inventors, after practice and careful research, found that the method commonly used in computer technology involving the rendering of virtual natural landscapes, which relies on manual modification of the background texture of the natural landscape to be rendered, still suffers from technical problems such as complex processes, large workload, poor reusability, and low flexibility. Therefore, the application scenario of this application can be a scenario involving the rendering of virtual natural landscapes in the field of computer technology, especially in the field of video games. The game types included in the aforementioned field of video games can be action, adventure, simulation, role-playing, and casual games, etc.

[0026] This application proposes a method for rendering virtual natural landscapes. It employs a base color map and normal map based on the virtual natural landscape, and utilizes the normal direction of the virtual vegetation model in the game scene and the coverage direction of the virtual natural landscape on the virtual vegetation model to render the virtual natural landscape. This technical concept reduces the performance consumption of rendering virtual natural landscapes on virtual fabrication models while improving the flexibility and reusability of the rendering process. It thus solves the technical problems of high performance consumption, poor rendering flexibility and reusability of virtual natural landscape rendering methods provided in related technologies.

[0027] The methods described in this application can be executed in a terminal device (e.g., a mobile terminal, a computer terminal, or a similar computing device). Taking a mobile terminal as an example, the mobile terminal can be a smartphone, tablet computer, PDA, mobile internet device, PAD, game console, or other terminal device.

[0028] Figure 1 This is a hardware structure block diagram of a mobile terminal for a method of rendering virtual natural landscapes according to one embodiment of this application. Figure 1 As shown, a mobile terminal may include one or more ( Figure 1 (Only one is shown) Processor 102, memory 104, transmission device 106, input / output device 108, and display device 110. Taking the method of rendering virtual natural landscapes applied to a video game scene via this mobile terminal as an example, processor 102 calls and runs the computer program stored in memory 104 to execute the method of rendering virtual natural landscapes. The virtual natural landscape on the rendered virtual vegetation model is transmitted to input / output device 108 and / or display device 110 through transmission device 106, thereby providing the virtual natural landscape to the player.

[0029] Still as Figure 1 As shown, the processor 102 may include, but is not limited to, processing devices such as: Central Processing Unit (CPU), Graphics Processing Unit (GPU), Digital Signal Processing (DSP) chip, Microcontroller Unit (MCU), Field Programmable Gate Array (FPGA), Neural-Network Processing Unit (NPU), Tensor Processing Unit (TPU), Artificial Intelligence (AI) type processor, etc.

[0030] Those skilled in the art will understand that Figure 1 The structure shown is for illustrative purposes only and does not limit the structure of the mobile terminal described above. For example, the mobile terminal may also include components that are more... Figure 1 The more or fewer components shown, or having the same Figure 1 The different configurations shown.

[0031] In some optional embodiments primarily focused on gaming scenarios, the aforementioned terminal device may also provide a human-computer interaction interface with a touch-sensitive surface. This interface can sense finger contact and / or gestures to interact with a graphical user interface (GUI). The human-computer interaction functions may include the following: creating web pages, drawing, word processing, creating electronic documents, playing games, video conferencing, instant messaging, sending and receiving emails, call interfaces, playing digital videos, playing digital music, and / or web browsing, etc. Executable instructions for performing the aforementioned human-computer interaction functions are configured / stored in one or more processor-executable computer program products or readable storage media.

[0032] The methods described in this application can also be executed on a server. The server can be a standalone physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server providing basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDN, and big data and artificial intelligence platforms. Taking the method of rendering virtual natural landscapes applied to a video game scene via a video game server as an example, the video game server can render virtual natural landscapes on a virtual vegetation model based on this method and provide the virtual natural landscapes to the player (e.g., by rendering and displaying them on the player's terminal screen, or by providing them to the player through holographic projection, etc.).

[0033] According to one embodiment of this application, an embodiment of a method for rendering virtual natural landscapes is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0034] This embodiment provides a method for rendering virtual natural landscapes that runs on the aforementioned mobile terminal. Figure 2 This is a flowchart of a method for rendering a virtual natural landscape according to one embodiment of this application, such as... Figure 2 As shown, the method includes the following steps:

[0035] Step S21: Determine the first coverage area of ​​the virtual natural landscape using the first direction and the second direction, wherein the first direction is the normal direction of the virtual vegetation model in the game scene, and the second direction is the coverage direction of the virtual natural landscape on the virtual vegetation model.

[0036] The aforementioned game scene can be a virtual game scene displaying virtual natural landscapes. The game type corresponding to this game scene can be: action (e.g., first-person or third-person shooter games, 2D or 3D fighting games, war action games, and sports action games), adventure (e.g., exploration games, collection games, puzzle games), simulation (e.g., simulation sandbox games, simulation management games, strategy simulation games, city building simulation games, business simulation games), role-playing games, and casual (e.g., board games, casual competitive games, music rhythm games, dress-up and simulation games), etc.

[0037] The game scene described above also includes virtual vegetation models, such as trees, shrubs, grass, and flowerbeds. The normal direction of this virtual vegetation model can be used as the first direction mentioned above (which can be represented in vector form). The virtual natural landscapes (such as frost and snow) can be overlaid on this virtual vegetation model. The direction in which the virtual natural landscapes overlay the virtual vegetation model can be used as the second direction mentioned above (which can be represented in vector form).

[0038] The first coverage area of ​​the virtual natural landscape is determined by using the normal direction of the virtual vegetation model in the game scene and the coverage direction of the virtual natural landscape on the virtual vegetation model. This first coverage area is used to render the virtual natural landscape on the virtual vegetation model.

[0039] Step S22: Determine the thickness information of the virtual natural landscape based on the first coverage area and the second direction;

[0040] Based on the aforementioned first coverage area and the coverage direction of the virtual natural landscape on the virtual vegetation model, the thickness information of the virtual natural landscape is determined. For example, this thickness information could be the thickness of the virtual snow model covering the virtual vegetation model.

[0041] Step S23: Through the first coverage area, perform transition processing on the first texture and the second texture to obtain the processing result, wherein the first texture is the base color texture of the virtual natural landscape and the second texture is the normal texture of the virtual natural landscape.

[0042] The first texture map mentioned above is used to determine the rendering color of the virtual natural landscape; this first texture map is the base color texture of the virtual natural landscape. The second texture map mentioned above is used to determine the 3D detail texture of the virtual natural landscape; this second texture map is the normal map of the virtual natural landscape.

[0043] By applying the first coverage area described above, the base color map and normal map of the virtual natural landscape are subjected to transition processing to obtain the processing result. This processing result can be a new blended map.

[0044] Step S24: Using thickness information, first coverage area and processing results, render virtual natural landscape on virtual vegetation model.

[0045] Using the thickness information of the virtual natural landscape, the first coverage area of ​​the virtual natural landscape on the virtual vegetation model, and the processing results, the virtual natural landscape is rendered on the virtual vegetation model.

[0046] It is easy to understand that the method for rendering virtual natural landscapes provided by steps S21 to S24 of this application does not require manual modification of the background texture of the natural landscape to be rendered. Based on the base color texture and normal texture of the virtual natural landscape, the virtual natural landscape is rendered using the normal direction of the virtual vegetation model in the game scene and the coverage direction of the virtual natural landscape on the virtual vegetation model.

[0047] In at least some embodiments of this application, a first coverage area of ​​the virtual natural landscape is determined using a first direction and a second direction. The first direction is the normal direction of the virtual vegetation model in the game scene, and the second direction is the coverage direction of the virtual natural landscape on the virtual vegetation model. Based on the first coverage area and the second direction, the thickness information of the virtual natural landscape is determined. Furthermore, the first texture and the second texture are subjected to transition processing through the first coverage area to obtain a processing result. The first texture is the base color texture of the virtual natural landscape, and the second texture is the normal texture of the virtual natural landscape. By utilizing the thickness information, the first coverage area, and the processing result, the virtual natural landscape is rendered on the virtual vegetation model, achieving the goal of rendering the virtual natural landscape on the virtual vegetation model at a lower cost. This achieves the technical effect of reducing the performance consumption of rendering the virtual natural landscape on the virtual fabrication model while improving the flexibility and reusability of the rendering process, thereby solving the technical problems of high performance consumption, poor rendering flexibility, and poor reusability of the virtual natural landscape rendering methods provided in related technologies.

[0048] The methods described in the embodiments of this application will be further described below.

[0049] Optionally, in step S21, determining the first coverage area of ​​the virtual natural landscape using the first direction and the second direction may include the following steps:

[0050] Step S211: Obtain the angle relationship between the first direction and the second direction;

[0051] Step S211: Determine the first coverage area based on the included angle relationship.

[0052] The angular relationship between the first and second directions mentioned above can include: perpendicular, parallel, and other angular relationships. The specific method for determining the first coverage area based on this angular relationship is as follows: areas where the angular relationship between the virtual vegetation model's normal direction (i.e., the first direction) and the virtual natural landscape's coverage direction of the virtual vegetation model (i.e., the second direction) is perpendicular are determined as areas that do not need to be covered; areas where the angular relationship between the virtual vegetation model's normal direction and the virtual natural landscape's coverage direction of the virtual vegetation model is parallel are determined as areas that need to be covered; using pre-specified parameters, areas where the angular relationship between the virtual vegetation model's normal direction and the virtual natural landscape's coverage direction of the virtual vegetation model is other angular relationships are calculated as areas that need to be covered; and finally, all areas on the surface of the virtual vegetation model that need to be covered are determined as the aforementioned first coverage area.

[0053] The method for rendering virtual natural landscapes provided in this application can be applied to scenarios involving the rendering of virtual natural landscapes in fields such as video games and virtual reality. This method is particularly suitable for scenarios in video games where virtual natural landscapes (such as snow layers) are rendered on virtual vegetation models. The following uses this scenario as an example to further illustrate the technical solution provided in this application.

[0054] In a video game scene where a snow layer is rendered on a virtual vegetation model, the normal direction of the virtual vegetation model (equivalent to the first direction mentioned above) and the coverage direction of the snow layer on the virtual vegetation model (equivalent to the second direction mentioned above) are first obtained, and the angle between the normal direction of the virtual vegetation model and the coverage direction of the snow layer on the virtual vegetation model is determined. Based on this angle relationship, the first coverage area is determined, which is the area to be rendered where the surface of the virtual vegetation model is covered with snow.

[0055] Figure 3 This is a schematic diagram of an optional snow cover area on a vegetation surface according to one embodiment of this application, as shown below. Figure 3 The image shows a cross-sectional view of a tree model covered with snow. Based on the normal direction of the tree model and the direction in which the snow layer covers the data model, it can be seen that... Figure 3 The area corresponding to the black line segment shown is defined as the area that needs to be covered with snow (equivalent to the first coverage area mentioned above).

[0056] Optionally, the virtual vegetation model includes: a virtual trunk model and a virtual branch model. The first direction includes: the trunk normal direction of the virtual trunk model and the branch normal direction of the virtual branch model. In step S211, obtaining the angle relationship between the first direction and the second direction may include the following steps:

[0057] Step S2111: Perform a dot product calculation on the direction of the main trunk normal and the second direction to obtain the first calculation result;

[0058] Step S2112: Convert the branch normal direction from tangent space to world space to obtain the conversion result;

[0059] Step S2113: Perform a dot product calculation on the transformation result and the second direction to obtain the second calculation result;

[0060] Step S2114: Determine the included angle relationship based on the first calculation result and the second calculation result.

[0061] Taking the rendering of a snow layer on a virtual vegetation model in a video game scene as an example, the virtual vegetation model includes a virtual trunk model and a virtual branch model. Correspondingly, the normal direction of the virtual vegetation model (equivalent to the first direction mentioned above) includes the trunk normal direction of the virtual trunk model and the branch normal direction of the virtual branch model.

[0062] The angle between the first and second directions is obtained by multiplying the normal direction of the virtual vegetation model (equivalent to the first direction mentioned above) and the coverage direction of the virtual natural landscape on the virtual vegetation model (equivalent to the second direction mentioned above).

[0063] For example, a virtual tree model includes a trunk model and branch models (including leaf models). When rendering a snow layer on a virtual tree model, the trunk and branch parts can be calculated and rendered separately.

[0064] Specifically, the branches of a virtual vegetation model are typically rendered using inlay textures. Therefore, when rendering a virtual natural landscape on a branch, the normal of that branch needs to be transformed from tangent space to world space first. Then, the normal of the branch is multiplied by the dot product of the virtual natural landscape's coverage direction on that branch, resulting in the second calculation result mentioned above. The trunk of a virtual vegetation model, however, usually does not require a spatial transformation of its normals; the normal of the branch is directly multiplied by the dot product of the virtual natural landscape's coverage direction on that trunk, resulting in the first calculation result mentioned above.

[0065] Based on the first and second calculation results mentioned above, the angular relationship between the normal direction of the virtual vegetation model and the coverage direction of the virtual natural landscape on the virtual vegetation model can be determined.

[0066] Based on the angle relationship between the first and second directions, for a point on the surface of the virtual vegetation model: when the first and second directions are perpendicular, the point is not covered by snow at all; when the first and second directions are parallel, the point is completely covered by snow; when the first and second directions are in other angular relationships, the degree of snow cover at the point is determined by the dot product of the first and second directions.

[0067] Optionally, in step S22, determining the thickness information of the virtual natural landscape based on the first coverage area and the second direction may include the following steps:

[0068] Step S221: Based on the first coverage area and the second direction, offset the model vertices of the virtual vegetation model to obtain the offset distance of the model vertices;

[0069] Step S222: Determine the thickness information using the offset distance.

[0070] The aforementioned thickness information can be used to determine the degree of offset of the model vertices of the virtual vegetation model. The higher the degree of offset, the greater the thickness value corresponding to the thickness information.

[0071] Taking the rendering of snow layer on a virtual vegetation model in a video game scene as an example, the model vertices of the virtual vegetation model are offset using the coverage area (equivalent to the first coverage area mentioned above) and coverage direction (equivalent to the second direction mentioned above) of the virtual natural landscape, to obtain the offset distance of the model vertices. The thickness of the snow layer is then determined using this offset distance.

[0072] It should be noted that the specific implementation of offsetting the model vertices of the virtual vegetation model can be: offsetting the model vertices of the virtual vegetation model to a new set of positions, or generating a new set of model vertices based on the model vertices of the virtual vegetation model and the second direction mentioned above.

[0073] It is easy to understand that the thickness of the snow layer is obtained by offsetting the model points of the virtual vegetation model. Therefore, it can be ensured that the rendered snow layer has a good virtual vegetation coverage effect (such as the surface shape of the snow layer corresponding to the surface shape of the virtual vegetation model covered by the snow layer).

[0074] Optionally, in step S23, the transition processing of the first texture and the second texture through the first coverage area, and the determination of the processing result may include the following execution steps:

[0075] Step S231: Using the first coverage area, a third texture is used to transition between the first texture and the second texture in the boundary area between the virtual natural landscape and the virtual vegetation model, and the processing result is determined. The third texture is a preset noise texture.

[0076] Taking the rendering of a snow layer on a virtual vegetation model in a video game scene as an example, based on the coverage area of ​​the snow layer on the virtual vegetation model (equivalent to the first coverage area mentioned above), the base color map and normal map of the virtual natural landscape are sampled, and a preset noise map is used to perform transition processing in the boundary area between the base color map and the normal map to obtain the processing result.

[0077] Figure 4 This is a schematic diagram of a base color map of a snow layer according to one embodiment of this application. Figure 5 This is a schematic diagram of a normal map of a snow layer according to one embodiment of this application. Figure 6 This is a schematic diagram of a noise map according to one embodiment of this application. Based on the area on the surface of the virtual vegetation model that needs to be covered with snow (equivalent to the first coverage area mentioned above), using... Figure 6 The noise map shown is for example Figure 4 The base color map shown and as Figure 5 The normal map shown is subjected to transition processing to determine the processing result. This processing result is used to determine the noise-style gradient effect at the boundary between areas on the virtual vegetation model surface that need to be covered with snow and areas that do not need to be covered with snow.

[0078] Therefore, on the surface of the virtual vegetation model, the area farther away from the coverage direction (i.e., the second direction) is more affected by the noise map, which in turn makes the boundary between the area that needs to be covered with snow and the area that does not need to be covered with snow on the surface of the virtual vegetation model have a noise pattern gradient effect, which is conducive to further improving the realism of the virtual natural landscape in the virtual scene.

[0079] Optionally, in step S24, rendering a virtual natural landscape on the virtual vegetation model using the thickness information, the first coverage area, and the processing result may include the following steps:

[0080] Step S241: Mix the first coverage area and the processing result to obtain the second coverage area;

[0081] Step S242: Render a virtual natural landscape on the virtual vegetation model based on the thickness information and the second coverage area.

[0082] Taking the rendering of a snow layer on a virtual vegetation model in a video game scene as an example, within the coverage area of ​​the snow layer on the virtual vegetation model, the processing result is blended onto the surface of the virtual vegetation model to obtain the second coverage area. During the blending process, the coverage area (i.e., the blending range) and blending intensity can be controlled using specified parameters. Further, based on the second coverage area and the thickness of the snow layer, a snow layer is rendered on the virtual vegetation model.

[0083] Specifically, still utilizing the area on the aforementioned virtual vegetation model that needs to be covered by a snow layer, as shown... Figure 6 The noise map shown is used as a weight to perform linear interpolation on the base color map and normal map after the above transition processing to obtain the second coverage area. The above linear interpolation can be represented as Lerp(original color of virtual vegetation model, snow layer color, noise map).

[0084] It should be noted that during the process of mixing the first coverage area and the processing result, parameters can also be used to control the range of snow cover that needs to be covered on the virtual vegetation model. For example, the interpolation result Lerp(completely covered area, completely uncovered area, dot product result) can be used to control the dot product result of the first and second directions; the function Step(dot product result, x) can be used to control "when the dot product result is not greater than x, the dot product result is set to 0 (corresponding to completely uncovered)"; and the parameter y can be used to control the curve of the dot product result function (e.g., changing the slope of the function by multiplying the dot product result by y, and controlling the speed of the snow layer change according to the angle between the first and second directions by setting the value of y).

[0085] Optionally, in step S242, rendering a virtual natural landscape on the virtual vegetation model based on the thickness information and the second coverage area may include the following steps:

[0086] Step S2421: Determine the third coverage area using the second coverage area and the area to be removed, wherein the area to be removed is the area in the virtual vegetation model that is not covered by the virtual natural landscape;

[0087] Step S2422: Render a virtual natural landscape on the virtual vegetation model based on the thickness information and the third coverage area.

[0088] After the aforementioned steps in this embodiment, the second coverage area may still include areas in the virtual vegetation model that are not covered by the virtual natural landscape (equivalent to the areas to be removed). Using the second coverage area and the areas to be removed, a third coverage area is determined. Further, based on the thickness of the snow layer and the third coverage area, a snow layer is rendered on the virtual vegetation model.

[0089] Optionally, in step S2421, determining the third coverage area using the second coverage area and the region to be removed may include the following steps:

[0090] Step S2423: Use a global masking drawing method to determine the area to be removed from the second coverage area;

[0091] Step S2424: Remove the area to be removed from the second coverage area to obtain the third coverage area.

[0092] The aforementioned global masking rendering method can identify and render a second coverage area using pre-defined shader code. From this second coverage area, the region of the virtual vegetation model not covered by the virtual natural landscape (equivalent to the aforementioned area to be removed) is determined. The area to be removed is then removed from the second coverage area to obtain a third coverage area, which is the area to be used for rendering the virtual landscape model on the virtual vegetation model. This allows for a more accurate determination of the areas on the surface of the virtual vegetation model that need to be covered with snow, thereby improving the realism of the rendering of the virtual natural landscape on the virtual vegetation model.

[0093] For example, areas that need to be identified as areas to be removed using the global masking drawing method described above include: areas where the normal of the tree trunk faces upwards, and areas in the tree trunk that are obscured by its own leaves.
