[0016] Embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings. While some embodiments of this disclosure are shown in the drawings, it should be understood that this disclosure can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of this disclosure. It should be understood that the accompanying drawings and embodiments of this disclosure are for illustrative purposes only and are not intended to limit the scope of protection of this disclosure.

[0017] It should be noted that the headings of any section / subsection provided herein are not limiting. Various embodiments are described throughout this document, and embodiments of any type may be included under any section / subsection. Furthermore, embodiments described in any section / subsection may be combined in any way with any other embodiments described in the same section / subsection and / or different sections / subsections.

[0018] In the description of embodiments of this disclosure, the term "comprising" and similar terms should be understood as open-ended inclusion, i.e., "including but not limited to". The term "based on" should be understood as "at least partially based on". The term "one embodiment" or "the embodiment" should be understood as "at least one embodiment". The term "some embodiments" should be understood as "at least some embodiments". Other explicit and implicit definitions may also be included below.

[0019] The embodiments of this disclosure may involve user data, data acquisition, and / or use. All of these aspects comply with applicable laws, regulations, and relevant provisions. In the embodiments of this disclosure, all data collection, acquisition, processing, manipulation, forwarding, and use are conducted with the user's knowledge and confirmation. Accordingly, in implementing the embodiments of this disclosure, the type, scope of use, and usage scenarios of any data or information that may be involved should be communicated to the user and their authorization obtained in accordance with relevant laws and regulations through appropriate means.

[0020] In this specification and the embodiments, any processing of personal information will be carried out only under the premise of legality (such as obtaining the consent of the personal information subject, or being necessary for the performance of a contract), and will only be carried out within the scope stipulated or agreed upon. A user's refusal to process personal information other than that necessary for basic functions will not affect the user's use of basic functions.

[0021] As briefly mentioned earlier, some complex virtual scenes currently involve drawing multiple different types of objects. In the rendering process of virtual scenes, depth information is used to represent the positional relationships between different objects. However, relying solely on depth information can lead to overly abrupt boundaries between some objects, resulting in an unrealistic image.

[0022] For example, Figure 1 An example of a drawn image 100 according to a conventional scheme is shown. In drawn image 100, there is adjacency between surface objects and rock objects. In a drawing example considering only depth information, such as Figure 1As shown, drawing image 100 may result in harsh dividing lines 110, which will greatly affect the realism of the image.

[0023] Embodiments of this disclosure propose a scheme for image rendering. According to various embodiments of this disclosure, an electronic device can render a set of objects in a virtual scene to generate a first set of pixels; adjust the overlay information of the first object in the set of objects in the virtual scene; render the first object in the set of objects based on the adjusted overlay information to generate a second set of pixels; determine a set of fused pixels associated with the first object based on the first set of pixels and the second set of pixels; and determine target rendering information of the set of fused pixels based on at least one of first rendering information of the first object and second rendering information of a second object associated with the fused region to render an image of the virtual scene, wherein the fused region is determined based on the set of fused pixels.

[0024] In this way, the embodiments of this disclosure can determine the object fusion area by drawing twice, and achieve the fusion drawing effect based on the drawing information of the object to be fused, thereby greatly improving the realism of the picture.

[0025] The following describes various example implementations of this solution in further detail with reference to the accompanying drawings. The embodiments of this disclosure can be applied to various fields such as simulation, modeling, virtual reality, and augmented reality.

[0026] Example Environment

[0027] Figure 2 A schematic diagram of an example environment 200 in which embodiments of the present disclosure can be implemented is shown. For example... Figure 2 As shown, example environment 200 may include terminal device 210.

[0028] In this example environment 200, terminal device 210 may run an application 220 that supports virtual scenes.

[0033] It should be understood that the structure and function of the various elements in environment 200 are described for illustrative purposes only and do not imply any limitation on the scope of this disclosure.

[0034] The following description will continue with reference to the accompanying drawings, which will provide some exemplary embodiments of this disclosure.

[0035] Example process

[0036] Figure 3 A flowchart of a process 300 for image drawing according to some embodiments of the present disclosure is shown. Process 300 can be implemented in a drawing device (e.g., Figure 2 The terminal device 210 and / or server 230 are located therein. For ease of discussion, reference will be made to... Figure 2 The environment 200 is used to describe the process 300.

[0037] In box 310, the drawing device draws a set of objects in the virtual scene to generate the first set of pixels.

[0038] In some embodiments, the rendering device can acquire object information in a virtual scene and render a set of objects included in the virtual scene accordingly. Such a set of objects can include any appropriate element in the virtual scene, such as surface objects, grass objects, stone objects, building objects, character objects, and so on.

[0039] In box 320, the drawing device adjusts the coverage information of the first object in a group of objects in the virtual scene.

[0040] In some embodiments, the rendering device may determine a first object in the virtual scene that needs to be included in the blending process. For example, such a first object may include a surface object in the virtual scene, thereby enabling the surface object to be blended with other objects on the adjacent surface.

[0041] It should be understood that the first object may also include other objects in the virtual scene that are suitable for fusion, such as sand, snow, and other appropriate objects.

[0042] In some embodiments, in order to determine the extent of the fusion region that needs to be merged with the first object, the rendering device may adjust the coverage of the first object in the virtual scene to cover more adjacent objects.

[0043] In some embodiments, the rendering device can adjust the height of the first object in the rendered image of the virtual scene. Taking a ground object as an example, the rendering device can, for instance, increase the height of the ground object in the rendered image of the virtual scene, thereby covering more of other objects on the ground, such as rocks, trees, etc.

[0044] In some other embodiments, the rendering device can also adjust the depth of the first object in the rendered image of the virtual scene. Continuing with the example of a surface object, the rendering device can, for instance, make the depth of the surface object closer to the viewpoint of the rendered image, thereby allowing it to, for example, cover more of other objects on the surface.

[0045] In some embodiments, the rendering device can adjust the coverage area of ​​the first object in the virtual scene by a preset amount. For example, the rendering device can adjust the height of the first object by a preset amount, or adjust the depth of the first object by a preset amount.

[0046] In box 330, the drawing device draws the first object in a set of objects based on the adjusted overlay information to generate the second set of pixels.

[0047] Furthermore, the rendering device can perform a secondary rendering of the first object based on the adjusted overlay information. In some embodiments, to save on pixel rendering pipeline (PS) overhead, the rendering device determines updated vertex information of the first object based on the adjusted overlay information; and renders the first object based on the updated vertex information.

[0048] Taking a surface object as an example, its number of pixels is much greater than its number of vertices. Therefore, the rendering device can determine the updated vertex information of the surface object and use the vertex rendering pipeline (VS) to render the surface object. Thus, embodiments of this disclosure can effectively save the cost of secondary rendering.

[0049] In box 340, the drawing device determines a set of merged pixels associated with the first object based on the first set of pixels and the second set of pixels.

[0050] The following combination Figures 4A to 4C To describe the specific process of determining a set of merged pixels. For example... Figure 4A As shown, Figure 4A The results of a depth test in the second set of pixels are shown after raising the surface object to a predetermined height. Figure 4A The retained pixel 410 is the first candidate pixel 410 in the second group of pixels that passed the depth test.

[0051] Specifically, the rendering device can determine the first group of candidate pixels 410 that pass the depth test from the second group of pixels based on the depth information of the first group of pixels and the second group of pixels. For example, after increasing the height of a surface object by a certain amount, the rendering device can compare the updated depth information of the surface object with the depth information of the original object in the virtual scene to determine the depth test result of the second group of pixels and retain the first group of candidate pixels 410 that pass the depth test.

[0052] In some embodiments, during the initial rendering process (i.e., the rendering process discussed in reference box 310), the rendering device may mark pixels associated with the first object to indicate that the pixel's stencil test result is failed. During rendering, the stencil test is used in conjunction with the depth test to determine whether a particular pixel's color value is retained or discarded. If the target test passes, the value is further processed, such as through blending operations, to ultimately obtain the pixel color to be rendered. Conversely, if the stencil test fails, no further processing is performed.

[0053] Furthermore, such as Figure 4B As shown, Figure 4B The results of a template test in a second set of pixels are shown, for example, after raising a surface object to a predetermined height. Figure 4B The retained pixel 420 is the second candidate pixel 420 in the second group of pixels that passed the depth test.

[0054] Specifically, the rendering device can determine a second set of candidate pixels 420 that pass the template test from the second set of pixels based on the template test information of the first set of pixels and the second set of pixels. In this way, if a pixel in the enhanced surface object still corresponds to an area of ​​the original surface object, such a pixel will not be retained as a candidate pixel 420.

[0055] Furthermore, such as Figure 4C As shown, the rendering device can determine a set of merged pixels 430 based on a first set of candidate pixels 410 and a second set of candidate pixels 420. Specifically, the rendering device can determine a set of merged pixels 430 based on the intersection of the first set of candidate pixels 410 and the second set of candidate pixels 420. For the above example, for instance, only pixels that pass both the stencil test and the depth test will be retained as a set of merged pixels 430 (e.g., ...). Figure 4C (As shown in the white part).

[0056] As can be seen, the number of pixels 430 in the group requiring fusion processing is significantly reduced compared to the number of pixels in the original surface area. Based on this approach, embodiments of this disclosure can quickly determine the fusion area requiring rendering with lower resource consumption.

[0057] Continue to refer to Figure 3 In box 350, the drawing device determines a set of target drawing information for fused pixels 430 based on at least one of first drawing information of a first object and second drawing information of a second object associated with the fused region, in order to draw an image of the virtual scene.

[0058] In some embodiments, the blending region is determined based on a set of blending pixels 430. For example, in a scenario where the first object is a surface object, the rendering device may determine one or more blending regions based on the positions of a set of blending pixels 430 to indicate the areas where the surface object is to be blended with one or more other objects of different types.

[0059] In some embodiments, the rendering device may determine a second object associated with the fused pixels corresponding to the fused region. Further, the rendering device may determine whether such a second object is suitable for fusion with the first object.

[0060] Examples of using surface objects as the first object, such as Figure 1 In the example, the stone object might be suitable for merging with the first object. However, for certain objects in a virtual scene, such as those associated with characters within the scene, merging with the first object might not be suitable. Typically, the elements representing a character should be independent; merging could result in a distorted effect.

[0061] In some embodiments, information regarding whether a second object is suitable for fusion with a first object can be pre-configured, for example, through fusion marker information. Such fusion marker information can be stored, for example, as a single bit of data in a template test. The rendering device can acquire the fusion marker information of the second object to determine whether it is suitable for fusion with the first object.

[0062] If it is determined that the second object is not suitable for merging with the first object, the drawing device may, for example, determine target drawing information for a set of merging pixels 430 based on the second drawing information of the second object. For example, the drawing device may directly retain the drawing result of the second object in the first drawing as the drawing result of the set of merging pixels 430, without performing the merging process of the first object and the second object.

[0063] Conversely, if it is determined that the second object is suitable for fusion with the first object, the drawing device can determine a set of fusion drawing information for fusion pixels 430 based on the first drawing information of the first object and the second drawing information of the second object.

[0064] In some embodiments, the rendering device may perform material fusion of the first object and the second object, rather than performing color fusion after determining the corresponding rendering colors. Specifically, the rendering device may, for example, determine the target rendering information of the set of fused pixels 430 during the geometry processing stage, and then, during the lighting processing stage, determine the lighting information of the image to be rendered based on the target rendering information, and further determine the final color information of the image.

[0065] In some embodiments, the drawing device may, for example, use a blending method to overlay the drawing result of the first object onto the original drawing result of the second object in a semi-transparent manner, thereby achieving material blending.

[0066] In some embodiments, the rendering device may also place the information of the target pixel that does not require fusion processing into the pixel's transparency channel (e.g., alpha channel), and during output, the alpha channel can retain its original information without being fused. Such information that does not require fusion processing may include, for example, the object's material ID.

[0067] In this scenario, under a blending-based processing approach, the primary colors (e.g., RGB color channel values) of different objects will be assigned a common blending weight. In some embodiments, such a blending weight can be determined, for example, by the distance from the pixel to be blended to the first object. The closer the pixel is to the first object, the higher the blending weight of the first object's primary color can be set, for example. Conversely, the farther the pixel is from the first object, the lower the blending weight of the first object's primary color can be set, for example.

[0068] In some embodiments, the rendering device can also acquire the rendered color information of the group of fused pixels 430 (e.g., corresponding to the second object). Specifically, when the rendering device is a mobile terminal, leveraging the advantages of tile rendering, the mobile terminal can acquire the color of the G-buffer of the pixel to be processed at virtually no cost. This reduces the cost of acquiring rendered color information.

[0069] In some embodiments, the rendering device can set different blending weights for different rendering attributes. For example, taking different primary colors as an example, the blending weights of the primary colors corresponding to the R, G, and B channels can be set to different weights.

[0070] For example, the first information of the target pixel (e.g., the value of the R primary color) may correspond to a first rendering attribute (e.g., the R primary color), and the second information (e.g., the value of the G primary color) may correspond to a second rendering attribute (e.g., the G primary color). In some embodiments, the first fusion weight used to determine the first information (e.g., the fusion weight used to fuse the R primary color) may be different from the second fusion weight used to determine the second information (e.g., the fusion weight used to fuse the G primary color). Based on this approach, embodiments of this disclosure can further provide flexibility in fusion.

[0071] Alternatively, other factors that can be used for blending include the material information of the objects, such as metallicity and roughness. The material information of the first object and the material information of the second object can also be blended accordingly based on the blending weights to determine the rendering information of the blended pixels.

[0072] Similarly, in performing blending based on different weights, the blending weights can be determined, for example, based on the distance from the target pixel to the first object, resulting in stronger blending of pixels adjacent to the first object and weaker blending of pixels farther from the first object. This can further improve the realism of object blending (e.g., blending surface objects with objects near the surface).

[0073] Based on the drawing process discussed above, the embodiments of this disclosure can determine the object fusion area through two drawing processes and achieve the fusion drawing effect based on the drawing information of the objects to be fused. Therefore, the present disclosure can greatly enhance the realism of the image by simulating the effect of material transitions.
