DepthTex

uniform sampler2D depthtexN;

There are three samplers for accessing the depth buffer.

• depthtex0 includes all geometry
• depthtex1 excludes transparent geometry
• depthtex2 excludes transparent and heldheld geometry

These buffers are written to by gbuffers programs, and store the screenspace z coordinate at each pixel. These buffers only store information in a single channel, the red component. The depth buffer precision is hardware/driver dependent, however most hardware uses either 24-bit or 32-bit precision. The depth buffers are the same resolution as the Minecraft window and this cannot be changed.

Legacy Alias

depthtex0 can be accessed through the legacy alias gdepthtex.
