Here is the shader code (I removed irrelevant details): Tags { "Queue" = "Transparent" "RenderType" = "Transparent" } CGPROGRAM. The result should be this: The variables are all half4 type, unity_SHAr and similar names. I didn't changed other graphics settings based on the default URP hub template switched to Android Platform. To correctly sample the depth buffer you should use LOAD_TEXTURE2D (with screen absolute coordinate) instead of SAMPLE. 1 depth (0 at eye, 1 at far plane) inline float Linear01Depth( float z ) {return 1. For that, I'm using two RF, one that draw meshes with a shader to create a mask and a RF that do some PP using this mask. 创作灵感查看更多. cginc which I don't fully understand.

Both functions take the raw depth value as input, but in URP, we also need to pass in a second parameter called _ZBufferParams, which is declared automatically and contains Simple Fog (URP). Linear01Depth(i):通过深度纹理 i 给出高精度值时,返回相应的线性深度,范围在 0 到 1 之间。 __注意:__在 DX11/12、PS4、XboxOne 和 Metal 中,Z 缓冲区范围是 1 到 0,并定义了 UNITY_REVERSED_Z。在其他平台上,范围是 0 到 1。 例如,以下着色器将渲染其游戏对象的深度: Linear01Depth(i): given high precision value from depth texture i, returns corresponding linear depth in range between 0 and 1. 因为除以f(远裁剪面),所以范围就在0到1之间. It looks like this: x is (1-far/near), y is (far/near), z is (x/far) and w is (y/far). y); However, this doesn't give me the depth in the linear01Depth space, so the ztest doesn't work correctly. If I sample just the red channel, I get the non-linear depthmap, and if I use Linear01Depth(), it goes mostly black: Question: What color format Using Depth Textures. Both LinearEyeDepth and Linear01Depth are expecting either the value from the _CameraDepthTexture or from the SV_POSITION variable's z component. 另外VertexShader中计算的屏幕坐标是齐次坐标,要换成真正的屏幕UV坐标,要去齐次。. CG和HLSL区别tags | 标签区别管线说明tags标签,URP的shader都需标明使用的渲染管线的标签,即"RenderPipeline"="UniversalRenderPipeline"。. 幸运的是,unity提供了两个辅助函数来为我们进行上述的计算过程——LinearEyeDepth和Linear01Depth。. r); "Linear01Depth" converts logarythmic depth into linear depth, but you already have linear depth on an orthographic camera, so just remove that function call. Then you can use the Render Texture in a Material just like a regular Texture. We archieve that by simply multiplying the linear depth we have now with the distance of the far clipping plane. Unity Version. Sep 27, 2022 · Choose bright colors for lights and use the Intensity property to boost or dim them. UNITY_TRANSFER_DEPTH(o): Deprecated.
