TrueColor uses an immutable colormap (it can't be changed). With DirectColor each of the red, green and blue channels has a separate color table which can be modified. In the case of a 24-bit/pixel visual there would be three 8-bit (256-entry) color tables. Per-channel gamma correction can be done with a DirectColor visual, for example. > But if you have a powerfull processor, couldnt be quicker to implement some > buffers via software if you have a not-so-powerfull 3d hardware? In principle, yes, but that's rare. > In other words, is it possible to tell glx to use the caveat-ed video modes? Sure. You could do that with glXChooseVisual. You'll naturally get a caveat-ed visual if that's all that's available. -Brian ------------------------------------------------------- Sponsored by: ThinkGeek at http://www.ThinkGeek.com/ _______________________________________________ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
