A scanout buffer is a buffer that the graphics chip reads from to directly display on the screen. There are other buffer types like texture and pbuffer that are not directly displayable. For example the Radeon r200 does not allow floating point colors in scanout buffers but they can be used in other buffer types. > > -- > Patrick "Diablo-D3" McFarland || [EMAIL PROTECTED] > "Computer games don't affect kids; I mean if Pac-Man affected us as kids, we'd > all be running around in darkened rooms, munching magic pills and listening to > repetitive electronic music." -- Kristian Wilson, Nintendo, Inc, 1989 > > > -- Jon Smirl [EMAIL PROTECTED] ------------------------------------------------------- SF.Net email is Sponsored by the Better Software Conference & EXPO September 19-22, 2005 * San Francisco, CA * Development Lifecycle Practices Agile & Plan-Driven Development * Managing Projects & Teams * Testing & QA Security * Process Improvement & Measurement * http://www.sqe.com/bsce5sf -- _______________________________________________ Dri-devel mailing list Dri-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/dri-devel
