The incredible coder Krzysztof "Deadwood" Smiechowicz has released an "alpha demo" of 3D acceleration under AROS, and you can already use it on Icaros Desktop 1.1.5, you just need a GeForce card supported by the nuveau driver (GeForce 4, FX, 6 and 7 series, except probably some cut-down models). Following the link below, you will get an updated version of AROS MESA-demos and, for your delight, a gallium-enabled port of Paolo Martella's GLExcess demo, which runs incredibly well on AROS. I have personally tested it at 1152x864 pixel on a GeForce 7800 card, and it runs amazingly well, at full framerate and without major issues (just some graphic glitch, mainly due to the status of the nuveau driver, still in development). To grab your little great demo of the incoming AROS' 3D capabilities, just follow this discussion on AROS-EXEC, and don't forget to write your feedback or to report any issue you'd encounter.
> Gallium 3D demo released on AROS-EXEC
1. download the gallium-0.1.zip archive with OWB
2. double click on it to extract it on a hard drive, a directory called Gallium-0.1 will be created.
3. select show -> all files and enter the Gallium-0.1 directory
4. open a shell with rAros+W
5. give these commands
glexcess-gallium 0 xxxx yyyy
(where xxxx and yyyy are your favourite screen resolution, eg 1280 1024 for 1280x1024 resolution)
Please remember you need a GeForce card. AROS must be booted with VESA graphics.
