| '''OpenGL extension EXT.clip_control |
| |
| This module customises the behaviour of the |
| OpenGL.raw.GLES2.EXT.clip_control to provide a more |
| Python-friendly API |
| |
| Overview (from the spec) |
| |
| This extension provides additional clip control modes to configure how |
| clip space is mapped to window space. This extension's goal is to 1) |
| allow OpenGL to effectively match Direct3D's coordinate system |
| conventions, and 2) potentially improve the numerical precision of the Z |
| coordinate mapping. |
| |
| This extension is a port of GL_ARB_clip_control to OpenGL ES. For the |
| complete overview of this extension, refer to the "Overview" section of |
| GL_ARB_clip_control. |
| |
| The official definition of this extension is available here: |
