GASP! Are there any cards or drivers that actually upload textures every frame? I can understand some vary special apps using real time generating of textures, but even that seams insane. That is to say that if the whole image was uploaded every frame. I know of at least one chip, don't laugh, but the VIC-20 (Yes, the C64) had support for this in 2D. A brief lesson in history, for those who where never there or don't remember. In the C-64, I still have my C64 if it's of any use :), there was only MMIO and one interrupt. Several MMIO to bring up the card, if you will, and set video mode. Then registers held an offset of where the sprite(a tiny page/frame/picture) lived and several others held it's position, if it was above or bellow text. So all you had to do to sprite flip was one memory write, and then marrio's legs would move, Then increment the X position address. There was also some feed back about things like when spites collide, I.E. you where hit buy that fire ball. Is there any thing like this for DRI? This to me would seem to be an important thing to add to the supported feature list. __________________________________________________ Do You Yahoo!?
