| '''OpenGL extension SGIX.interlace |
| |
| This module customises the behaviour of the |
| OpenGL.raw.GL.SGIX.interlace to provide a more |
| Python-friendly API |
| |
| Overview (from the spec) |
| |
| This extension provides a way to interlace rows of pixels when |
| rasterizing pixel rectangles, and loading texture images. In this |
| context, interlacing means skiping over rows of pixels or texels |
| in the destination. This is useful for dealing with video data |
| since a single frame of video is typically composed from two images |
| or fields: one image specifying the data for even rows of the frame |
| and the other image specifying the data for odd rows of the frame. |
| |
| The official definition of this extension is available here: |
| http://www.opengl.org/registry/specs/SGIX/interlace.txt |
