Web18 de nov. de 2024 · The following linear function transforms the z-value to a depth value between 0.0 and 1.0: F d e p t h = z − n e a r f a r − n e a r Here, n e a r and f a r are the distances of the near and the far plane. The result is a linear mapping: you are 'scaling' and applying an offset to some values so that they fit a different scale range.
