People did Xshm based 3D in a window stuff using Voodoo2 cards and Xshm type stuff. Unfortunately that means pulling data over PCI which is slow, and sucks totally. To get it to work well you need a card that can push data by DMA from the framebuffer to the other card and kernel side driver code to do the push triggering since XFree86 Get/PutImage methods don't do DMA (tiled DMA Get/PutImage would actually make Xrender fast..) ------------------------------------------------------- This SF.Net email sponsored by: Free pre-built ASP.NET sites including Data Reports, E-commerce, Portals, and Forums are available now.
