| | '''OpenGL extension SGIX.flush_raster |
| | |
| | This module customises the behaviour of the |
| | OpenGL.raw.GL.SGIX.flush_raster to provide a more |
| | Python-friendly API |
| | |
| | Overview (from the spec) |
| | |
| | This extensions provides a way to ensure that all raster operations |
| | currently in the pipeline will be completed before the next |
| | raster operation begins. We define a raster operation as an operation |
| | that involves the rasterization stage of the OpenGL pipeline. |
| | The implementation is free to decide what consitutes flushing the |
| | raster subsystem. |
| | |
| | The motivation is to allow accurate instrumentation by |
| | including this call before stopping rasterization measurements. |
| | There are cases where Finish() is used, but a FlushRaster() |
| | would suffice, so this extension is deliberately kept independent |
| | of the instruments extension. |
| | |
| | The official definition of this extension is available here: |
