[0002] With the continuous improvement of game rendering technology, most game rendering effects are now achieved through physically based rendering (PBR) rendering workflow. The PBR rendering workflow aims to reproduce the behavior of light and objects interacting in the real world based on the principles of physics and microplanes, so as to reproduce the material properties of most real-world substances in the game.
[0003] However, even though the PBR rendering process is now quite mature, rendering realistic semi-transparent materials in games remains a challenge due to the many unique physical properties they typically possess, such as reflection, refraction, total internal reflection, and thickness. This is especially true when a semi-transparent material is partially above water and partially underwater, making it difficult to render the true texture of the material in both its above-water and underwater states, often resulting in poor rendering quality.

[0031] To make the objectives, technical solutions, and beneficial effects of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0032] This application provides a method for rendering semi-transparent materials in games. This method can be applied to electronic devices such as computing devices and user terminals. The computing devices include, but are not limited to, servers and virtual machines, while the user terminals include, but are not limited to, mobile phones, tablets, PDAs, laptops, and desktop computers. See also... Figure 1 As shown in the embodiments of this application, the general flow of the semi-transparent material rendering method in games is as follows:
[0033] Step 101: Determine the game scene to be rendered; the game scene includes semi-transparent materials and water.
[0034] In practical applications, electronic devices can determine all game scenes, including those with translucent materials and water, as the game scenes to be rendered, or they can determine only certain parts of the game scenes, including those with translucent materials and water, as the game scenes to be rendered, depending on actual needs.
[0035] Step 102: Based on the positional relationship between the semi-transparent material and the water in the game screen, determine the first part of the semi-transparent material located on the water and the second part located inside the water.
[0036] In practical applications, when electronic devices determine the first part of the translucent material located on the water and the second part located within the water based on the positional relationship between the translucent material and the water in the game screen, the steps may include, but are not limited to, the following:
[0037] Step a: The electronic device determines the horizontal plane segmentation range of the water body on the semi-transparent material based on the water surface height in the game screen. In specific implementation, the electronic device can determine the horizontal plane segmentation range of the water body on the semi-transparent material based on the relationship between the coordinate height of each pixel in the game screen and the water surface height. For example, the electronic device can use the following formula (1) to obtain... Figure 2a The water body shown is divided into horizontal planes on a translucent material.
[0038] inOutOcean=step(oceanHeight, input.positionWS.y)...Formula (1)
[0039] Wherein, inOutOcean represents the horizontal plane segmentation range, oceanHeight represents the water surface height, input.positionWS.y represents the coordinate height (i.e., y-axis coordinate) of each pixel corresponding to the semi-transparent material in the game screen, and step() represents the output of 0 when input.positionWS.y is less than oceanHeight and the output of 1 when input.positionWS.y is greater than oceanHeight.
[0040] Step b: Based on the scene depth map and water surface undulation control parameters of the game screen, the electronic device determines the water surface undulation segmentation range on the semi-transparent material. In specific implementation, the electronic device may adopt, but is not limited to, the following methods:
[0041] First, the electronic device samples the scene depth map based on the pixel coordinates of the game screen to obtain the scene depth map of the game screen. For example, the electronic device can use the following formula (2) to obtain the scene depth map of the game screen.
[0042] sceneDepth=SAMPLE_DEPTH_TEXTURE_LOD(CameraDepthTexture,samplerCameraDepthTexture,screenUV,0)...Formula (2)
[0043] Among them, sceneDepth represents the scene depth map, SAMPLE_DEPTH_TEXTURE_LOD() represents the depth map sampling function, CameraDepthTexture represents the scene depth map, samplerCameraDepthTexture represents the depth map sampling method, and screenUV represents the pixel coordinates of the game screen.
[0044] Secondly, the electronic device performs a perspective transformation on the scene depth map of the game screen to obtain the target scene depth map of the game screen. For example, the electronic device can use the following formula (3) to obtain the target scene depth map of the game screen.
[0045] sceneZ=LinearEyeDepth(sceneDepth)...Formula (3)
[0046] Here, sceneZ represents the target scene depth map, sceneDepth represents the scene depth map, and LinearEyeDepth() represents the viewpoint transformation function.
[0047] Then, the electronic device performs perspective division correction on the target scene depth map of the game screen to obtain the corrected scene depth map of the game screen.
[0048] Finally, the electronic device determines the range of water surface undulations on the translucent material based on the water surface undulation control parameters, the target scene depth map, and the corrected scene depth map. For example, the electronic device can use the following formula (4) to obtain... Figure 2b The water body shown is depicted as exhibiting the range of surface undulations on a translucent material.
[0049] waveRange=1–saturate(sceneZ-screenPosition.w)*Range…Formula (4)
[0050] Among them, waveRange represents the range of water surface undulation, sceneZ represents the target scene depth map, screenPosition.w represents the corrected scene depth map, Range represents the water surface undulation control parameter, and saturate() represents limiting the difference between sceneZ and screenPosition.w to [0, 1].
[0051] Step c: The electronic device determines the target above-water and underwater segmentation range of the translucent material based on the horizontal plane segmentation range and the water surface undulation segmentation range. For example, the electronic device can use the following formula (5) to obtain... Figure 2c The target underwater and above-water segmentation range is shown as a semi-transparent material.
[0052] oceanRange=max(inoutOcean,waveRange)...Formula (5)
[0053] Among them, oceanRange represents the target water surface and underwater segmentation range, inoutOcean represents the horizontal plane segmentation range, waveRange represents the water surface undulation range, and max() represents taking the maximum value of inoutOcean and waveRange.
[0054] Step d: Based on the target above-water and underwater segmentation range of the translucent material, the electronic device determines the first part of the translucent material located on the water body and the second part located inside the water body.
[0055] Step 103: Use the PBR lighting model to render the semi-transparent material to obtain the original rendering effect.
[0056] In practical applications, PBR rendering can usually reproduce the behavior of light interacting with objects in the real world. Therefore, in the embodiments of this application, electronic devices can also use the PBR lighting model to perform preliminary rendering of semi-transparent materials to obtain the original rendering effect of semi-transparent materials.
[0057] Step 104: Based on the original rendering effect of the second part of the semi-transparent material, underwater visibility, and underwater refractive index, render the second part of the semi-transparent material to obtain the underwater rendering effect of the second part of the semi-transparent material.
[0058] In practical applications, before rendering the second part of the semi-transparent material based on its original rendering effect, underwater visibility, and underwater refractive index to obtain the underwater rendering effect, electronic devices can first determine the underwater visibility and underwater refractive index of the semi-transparent material. Specifically, electronic devices can use, but are not limited to, the following methods:
[0059] First, the electronic device obtains the underwater visibility of the second part of the translucent material by simulating fog, based on the scene depth map and fog color values of the game screen. For example, the electronic device can obtain the underwater visibility of the second part of the translucent material using the following formula (6).
[0060] oceanFog=FogColor*sceneDepht...Formula (6)
[0061] Among them, oceanFog represents underwater visibility, FogColor represents fog color value, and sceneDepht represents scene depth map.
[0062] Secondly, the electronic device performs a refraction offset on the first texture coordinates of the second part of the semi-transparent material based on the noise map of the semi-transparent material to obtain the second texture coordinates of the second part of the semi-transparent material. For example, the electronic device can use the following formula (7) to obtain the second texture coordinates of the second part of the semi-transparent material.
[0063] refractionOffset=SAMPLE_TEXTURE2D(RefractionMap,samplerRefractionMap,input.uv.xy).x...Formula (7)
[0064] Among them, refractionOffset represents the second texture coordinates of the second part of the semi-transparent material, SAMPLE_TEXTURE2D() represents the texture sampling function, RefractionMap represents the noise map of the semi-transparent material, samplerRefractionMap represents the sampling method of the noise map, and input.uv.xy represents the first texture coordinates of the second part of the semi-transparent material.
[0065] Then, the electronic device samples the opaque map of the water body based on the second map coordinates of the second part of the semi-transparent material to obtain the underwater refractive index of the second part of the semi-transparent material. For example, the electronic device can obtain the underwater refractive index of the second part of the semi-transparent material using the following formula (8).
[0066] refraction=SAMPLE_TEXTURE2D(CameraOpaqueTexture,samplerCameraOpaqueTexture,screenUV uv+refractionOffset).rgb...Formula (8)
[0067] Here, refraction represents the underwater refractive index of the second part of the semi-transparent material, SAMPLE_TEXTURE2D() represents the texture sampling function, CameraOpaqueTexture represents the opaque texture of the water body, samplerCameraOpaqueTexture represents the sampling method of the opaque texture, screenUV uv represents the pixel coordinates of the semi-transparent material, and refractionOffset represents the second texture coordinates of the second part of the semi-transparent material.
[0068] Finally, based on the original rendering effect of the second part of the semi-transparent material, underwater visibility, and underwater refractive index, the electronic device performs linear interpolation on the scene depth map of the game screen to obtain the underwater rendering effect of the second part of the semi-transparent material. For example, the electronic device can use the following formula (9) to obtain the underwater rendering effect of the second part of the semi-transparent material.
[0069] underSeaGlass=lerp(refraction,oriGlass+oceanFog,sceneDepht)
[0070] ...Formula (9)
[0071] Among them, underSeaGlass represents the underwater rendering effect of the second part of the semi-transparent material, refraction represents the underwater refractive index of the second part of the semi-transparent material, oriGlass represents the original rendering effect of the semi-transparent material, oceanFog represents the underwater visibility, sceneDepht represents the scene depth map of the game screen, and lerp() represents linear interpolation.
[0072] Step 105: Based on the original rendering effect of the semi-transparent material and the underwater rendering effect of the second part of the semi-transparent material, obtain the target rendering effect of the semi-transparent material.
[0073] In practical applications, electronic devices can perform linear interpolation on the original rendering effect of the semi-transparent material and the underwater rendering effect of the second part of the semi-transparent material based on the target underwater segmentation range of the semi-transparent material to obtain the target rendering effect of the semi-transparent material. For example, electronic devices can use the following formula (10) to obtain the target rendering effect of the semi-transparent material.
[0074] finalGlass=lerp(oriGlass,underSeaGlass,oceanRange)...Formula (10)
[0075] Among them, finalGlass represents the target rendering effect of the semi-transparent material, oriGlass represents the original rendering effect of the semi-transparent material, underSeaGlass represents the underwater rendering effect of the second part of the semi-transparent material, oceanRange represents the target underwater segmentation range, and lerp() represents linear interpolation.
[0076] In this embodiment, by determining the first part of the semi-transparent material located on the water and the second part located inside the water based on the positional relationship between the semi-transparent material and the water in the game screen, the boundary between the semi-transparent material above and below the water can be effectively restored when the water flows. Moreover, after initially rendering the semi-transparent material in the game screen using the PBR lighting model, the second part of the semi-transparent material is further rendered based on the original rendering effect, underwater visibility, and underwater refractive index. This can also effectively restore the realistic texture of the semi-transparent material underwater, thereby effectively distinguishing the rendering effect of the semi-transparent material in different states above and below the water, and thus improving the rendering effect of the semi-transparent material in different states above and below the water.
[0077] In most games, there are often various semi-transparent materials that need to be rendered, such as glass on buildings. Since glass usually has physical properties such as reflection, refraction, total internal reflection, and thickness, it is often difficult to render the realistic texture of glass in different states above and below water using existing PBR lighting models. Therefore, when rendering glass, the semi-transparent material rendering method in the game provided in this application embodiment can be used to realize the rendering effect of glass in different states above and below water, thereby improving the overall rendering effect of glass in different states above and below water.
[0078] The following section uses glass as an example to illustrate the rendering method for semi-transparent materials in games provided in this application. Please refer to [link / reference].

[0081] Step 303: The electronic device samples the scene depth map based on the pixel coordinates of the game screen and uses the above formula (2) to obtain the scene depth map of the game screen.
[0082] Step 304: The electronic device uses the above formula (3) to perform a perspective transformation on the scene depth map of the game screen to obtain the target scene depth map of the game screen.
[0083] Step 305: The electronic device performs perspective division correction on the target scene depth map of the game screen to obtain the corrected scene depth map of the game screen.
[0084] Step 306: The electronic device uses the above formula (4) to determine the range of water surface undulation on the glass material based on the water surface undulation control parameters, the target scene depth map and the corrected scene depth map.
[0085] Step 307: The electronic device determines the target water surface and underwater segmentation range of the glass material based on the horizontal plane segmentation range and the water surface undulation segmentation range using the above formula (5).
[0086] Step 308: The electronic device determines the first part of the glass material located on the water body and the second part located inside the water body based on the target above-water and underwater segmentation range of the glass material.
[0087] Step 309: The electronic device uses a PBR lighting model to render the glass material to obtain the original rendering effect.
[0088] Step 310: The electronic device uses the above formula (6) to simulate fog based on the scene depth map and fog color value of the game screen to obtain the underwater visibility of the second part of the glass material.
[0089] Step 311: Based on the noise map of the glass material, the electronic device uses the above formula (7) to refract and offset the first texture coordinates of the second part of the glass material to obtain the second texture coordinates of the second part of the glass material.
[0090] Step 312: The electronic device samples the opaque texture of the water body based on the second map coordinates of the second part of the glass material using the above formula (8) to obtain the underwater refractive index of the second part of the glass material.
[0091] Step 313: Based on the original rendering effect of the second part of the glass material, underwater visibility and underwater refractive index, the electronic device uses the above formula (9) to linearly interpolate the scene depth map of the game screen to obtain the underwater rendering effect of the second part of the glass material.
[0092] Step 314: Based on the target underwater and above-water segmentation range of the glass material, the electronic device uses the above formula (10) to linearly interpolate the original rendering effect of the glass material and the underwater rendering effect of the second part of the glass material to obtain the target rendering effect of the glass material.
