| | '''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 |
