You've substituted the original linearizeDepth equation with something that different. The original linearizeDepth function is based on this formula.. Note that if you attempt to derive the function based on this formula you'll see that it's actually the inverse of Z that the linearizeDepth function … In OpenGL it's -1 to 1 and in Vulkan it's 0 to 1. However, in OpenGL when the depth is stored into a depth texture and you read from it, the value is further normalized to 0 to 1. This seems to be the case in your example, since the first line of your function maps it back to -1 to 1. laporan arus kas direct
