| | '''OpenGL extension SGI.make_current_read |
| | |
| | This module customises the behaviour of the |
| | OpenGL.raw.GLX.SGI.make_current_read to provide a more |
| | Python-friendly API |
| | |
| | Overview (from the spec) |
| | |
| | The association of the current context with a drawable is extended to allow |
| | separate write and read drawables. This paves the way for allowing |
| | preprocessing of image data in an "off screen" window which is then read |
| | into the visible window for final display. Similarly it sets the |
| | frame-work for direct transfer of video to the GL, by treating the video |
| | as a special kind of read drawable (a.k.a, readable). |
| | |
