while the NDCS is a right-hand one. If we focus on the Z-axis, then the transform from VCS to NDCS is given as follows: The Z-coordinate in SCS is obtained from the one in NDCS with the following simple conversion in case of OpenGL. Z*_ndcs is the sampled and interpolated value of Z_ndcs. The depth
