The result is a linear mapping: you are 'scaling' and applying an offset to some values so that they fit a different scale range.

WebSee in Glossary all support depth textures. OpenGL ES 2.0 ... Linear01Depth(i): given high precision value from depth texture i, returns corresponding linear depth in range between 0 and 1. Note: On DX11/12, PS4, XboxOne and Metal, the Z buffer range is 1–0 and UNITY_REVERSED_Z is defined. Web1. Depth buffer values are clamped to that range because usually they are using fixed-point representation, so if clipping is disabled (by glEnable (GL_DEPTH_CLAMP)) then they can't hold anything beyond that range. However, there isn't really a good reason for this clamping when floating point depth buffers are used.
