Nettet25. nov. 2024 · As commented, these functions are the inverse of the Linear01Depth and LinearEyeDepth. They also handle the Direct3D vs OpenGL platform differences for us too, so a UNITY_REVERSED_Z check is not needed when using these. Note that you shouldn’t use SV_Depth without a good reason, as it turns off early-z/depth testing … Nettet18. aug. 2024 · Linear01Depth関数 Zバッファを線形な0～1の深度値に変換 (0は目の位置，1はfar面) inline float Linear01Depth( float z ) { return 1.0 / (_ZBufferParams.x * z + _ZBufferParams.y); } harbor freight hammer drill chisel https://robina-int.com

Nettet1. jul. 2024 · Summary In the last tutorial I explained how to do very simple postprocessing effects. One important tool to do more advanced effects is access to the depth buffer. It’s a texture in which the distance of pixels from the camera is saved in.
