| | '''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 |
