RISC OS Hardware accelerated 3D graphics on RISC OS took a step closer to reality, thanks to Simon Wilson. He claims to have ported Mesa 3.2, a 3D graphics library that sports an OpenGL software interface. More importantly, he says he has also ported an Nvidia graphics accelerator from BeOS to harness the GeForce2 video card in the Iyonix to plot graphics fast in hardware.

All current development is happening on DRM/DRI/mesa6.

Whenever Xegl is ready, it should be simpler to port to other OSes than the current DRI/x pair. Xegl isolates most of the OS specific code into the fbdev/DRM device drivers.

But isn't the point of Ruldolf's driver project to make an OPEN-SOURCE 3d driver? -- from what I understand the DRM/DRI device drivers rely on a binary driver compiled and distributed by the vendor - which locks it into a specific model and architecture.

Rudolf's driver is independent of any code provided by nVidia, and he has done much work to reverse-engineer the video cards for his own 2d/3d acceleration drivers.

DRM/DRI isn't dependent on binary drivers. Indeed, NVIDIA's binary drivers don't even use the DRI/DRM. On the other hand, open source DRI drivers exist for a number of chipsets, including Radeons.
