The Interlace Extension

The Interlace Extension

The interlace extension, SGIX_interlace, provides a way to interlace rows of pixels when rasterizing pixel rectangles, or loading texture images. In this context, interlacing means skipping over rows of pixels or texels in the destination. This is useful for dealing with interlace video data since single frames of video are typically composed of two fields: one field specifies the data for even rows of the frame, the other specifies the data for odd rows of the frame.

Caution: This extension is an SGIX (experimental) extension. The interface may change, or it may be dropped altogether.
