Besides the cube, there was a sphere, an open book, and a pulsing surface that looked like water that a pebble has been dropped into. Furthermore, the cube could be rotated by the user dragging the mouse. In general, texture mapping is straightforward enough, and a PowerPC 604 has enough horsepower to solve it in the general case, that I'm sure that's what they did. In other words, of course the hidden surfaces wouldn't be rendered, but your other suggestions sound a little wacky. Anyway, I didn't mean to bring BeOS into this, except that it's curious that you should announce a driver for a card that I first heard of in connection with the Be demo at MacWorld. I'll have to buy the card and let you know how it works. Maybe I can sneak it into work one day and try it out on the MBONE to FreeBSD Lounge, if I can find a Pentium to sneak FreeBSD onto. :) P.S. I just saw a demo of SGI's new Octane system on the MBONE. Using Alias Wavefront, they did a real-time walkthrough of a robot walking along a street with rain and streetlights! They also showed a dragon flapping its wings rendered in real-time with SoftImage, and emphasized the fact that even though they're a subsidiary of Microsoft now, it still runs best on SGI's! If only I had $25,000 (or whatever the price is after educational discount :) ... ------------------------------------------------------------------------------ |Jake Hamby| Ask me about Unix, FreeBSD, Solaris, The Tick, BeOS, or NT, eh? | ------------------------------------------------------------------------------ "This space intentionally left blank."
