| '''OpenGL extension IBM.cull_vertex |
| |
| This module customises the behaviour of the |
| OpenGL.raw.GL.IBM.cull_vertex to provide a more |
| Python-friendly API |
| |
| Overview (from the spec) |
| |
| IBM_cull_vertex provides a subset of the vertex culling functionality |
| found in EXT_cull_vertex without providing a guarantee that faces will |
| be culled because of it. EXT_cull_vertex is a technically superior |
| solution, but the vertex culling aspect of IBM_cull_vertex provides |
| generally useful function cheaply (without imposing the mandated |
| culling found in EXT_cull_vertex). |
| |
| The official definition of this extension is available here: |
| http://www.opengl.org/registry/specs/IBM/cull_vertex.txt |
