At the SGI booth at SIGGRAPH last year, one of the demos on the GTX presented a window repeatedly replaying a short segment of previously captured NTSC video. Was this accomplished by filling up the framebuffer with the images and copying them one after another into the visible window, or did the images come from main memory?

That program is called 'blast', and it stored its images in main memory (I believe that demo needed at least 32 megabytes of real memory...) There are two other demos, 'cine' and 'cinebw', that store their images in frame buffer memory; they both take over the entire screen, while blast runs in its own window (cinebw handles black&white images, cine does full-color RGB images). --gavin (gavin@sgi.com) Disclaimer: I make just as many dumb little mistakes as anybody...

I don't know if perchance you're refering to the demo that Hannaway & Associates were playing on their GTX. Was the sequence you saw a cowboy galloping on a horse? If so it was them and if you need their number I can give it to you.
