| | '''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: |
