Web2 de jan. de 2024 · This method is a two step process. We first compute P z, the eye-space Z coordinate. Then use that to compute the full eye-space position. The first part is actually quite easy. Most of the computations we used above were necessary because we needed C w, which we had to do since we needed a full clip-space position. Web15 de jan. de 2015 · From here, it is easy to re-construct world space position without the steps taken. We simply have to buffer our rekernelized sample depth multiplied by our kernel-space occlusion factor (This is the inverse of the original process used to derive the occlusion value). Here is some GLSL code which explains the process in more detail: fishing rentals
