| | '''OpenGL extension IBM.rasterpos_clip |
| | |
| | This module customises the behaviour of the |
| | OpenGL.raw.GL.IBM.rasterpos_clip to provide a more |
| | Python-friendly API |
| | |
| | Overview (from the spec) |
| | |
| | IBM_rasterpos_clip extends the semantics of the RasterPos functions. It |
| | provides an enable that allows a raster position that would normally be |
| | clipped to be treated as a valid (albeit out-of-viewport) position. |
| | |
| | This extension allows applications to specify geometry-aligned pixel |
| | primitives that may be partially off-screen. These primitives are |
| | tested on a pixel-by-pixel basis without being rejected completely |
| | because of an invalid raster position. |
| | |
| | The official definition of this extension is available here: |
| | http://www.opengl.org/registry/specs/IBM/rasterpos_clip.txt |
