| '''OpenGL extension AMD.depth_clamp_separate |
| |
| This module customises the behaviour of the |
| OpenGL.raw.GL.AMD.depth_clamp_separate to provide a more |
| Python-friendly API |
| |
| Overview (from the spec) |
| |
| The extension ARB_depth_clamp introduced the ability to control |
| the clamping of the depth value for both the near and far plane. |
| One limitation is that the control was for both planes at the |
| same time; some applications can benefit from having clamping |
| enabled for only one of the two planes, in order to save |
| fillrate for the other plane by clipping the geometry. |
| |
| This extension provides exactly such functionality. |
| |
| The official definition of this extension is available here: |
| http://www.opengl.org/registry/specs/AMD/depth_clamp_separate.txt |
