Vandaag een interessante aflevering van de Ask Hook column van Voodoo Extreme. Hier de vraag:
OK, so we're getting the first hardware T&L chips RealSoonNow. And they'll be nice 'n fast, and nice 'n sterile. Looking over the GeForce256 specs, I see a shocker: support for only 8 lights. Now, I don't mean to rain on NVidia's parade here, but that's just silly. In the WorldOfQuake, that's 8 rockets flying through the air; or "lower end of activity" for a 2on2 match.
What does it really mean to say that the GeForce supports 8 hardware lights?
Is "8" just an arbitrary number and the driver will handle 'cycling' the 100 or so actual lights thru the 8 little "lightme" units? Or is there a viable way to have the CPU handle lights beyond the 8 the card will do? Or can we 'cycle' those 8 lights through all the places we need them (like the old c64 trick of making 8 sprites perform like 16 by beating the raster down the screen)?
Or are we just SOL with our eight flashlights for 20 partygoers?
