Web3 de fev. de 2011 · OpenGL splits definition of the viewport transformation matrix into glViewport and glDepthRange calls. glDepthRange is what controls the scale factor responsible for determining the depth range you are asking about. You can call glGetFloatv with the GL_DEPTH_RANGE selector to recover the current range. Web6 de jan. de 2024 · MinZ and MaxZ indicate the depth-ranges into which the scene will be rendered and are not used for clipping. Most applications will set these members to 0.0 and 1.0 to enable the system to render to the entire range of depth values in the depth buffer. In some cases, you can achieve special effects by using other depth ranges.

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.
