Question by Nicolas-Liatti · Mar 01, 2017 at 05:30 AM · shader programming

Decode depth in DepthNormals mode

Hi,

I need to convert a shader which is in depthTextureMode set to Depth, to DepthNormals.

In my shader in Depth mode I have

// Reconstruct world space position and direction float rawdpth = SAMPLE_DEPTH_TEXTURE(_CameraDepthTexture, i.uv_depth); float3 wsDir = i.interpolatedRay * Linear01Depth(rawdpth); // for PERSPECTIVE float3 wsPos = _CameraWS + wsDir;

I tried to replace it by // Reconstruct world space position and direction

float4 currentDepthNormal = tex2D(_CameraDepthTexture, i.uv);

float rawdpth; float3 currentPixelNormal; DecodeDepthNormal(currentDepthNormal, rawdpth, currentPixelNormal); float3 wsDir = i.interpolatedRay * Linear01Depth(rawdpth); // for PERSPECTIVE float3 wsPos = _CameraWS + wsDir;

But it doesn't give me the good result, it still seems to take the normal into account... Any idea how to get only the depth?

Thanks!
