T-Buffer (Read 209 times)

sb306 Full Member Offline I hate Nvidia! Posts: 154 Fresno ca, U.S. Gender:	T-Buffer 04.03.09 at 13:26:04 I know the advertising and specs for the v5500 mention a t-buffer. But I've never seen anything about it anywhere. There is nothing about t-buffer in the 3dfx utility either. Any help would be apprciated. Thanks.

Yep.

The additional features like mentioned would have required specific software support, so the game/demo would have had to know, when and where to apply Motion Blur for instance, or everything would have been blurred (not good!). Same goes for the other effects. For FSAA it was possible to apply it globally, as this resulted in the exact desired effect..

Another example for Motion Blur is the Quake 3 Arena Techdemo for 3dfx cards, which showed off some Motion Blur via OpenGL, talking to the T-Buffer directly via some MiniGL extension I believe (but unsure).
