OpenGL on RISCOS
All the demos use software rendering. The frame rates are quite low even running on a Pandaboard ES @ 1500Mhz. They use SDL 1.2.15 for the display and OSMesa 7.10.3 for rendering and were built using GCCSDK 4.6.4.
The following downloads are for RISC OS only. They should work on any machine running RISC OS 3.6 or greater. The frame rate will be extremely low unless running on at least a Beagleboard xM. The faster the machine the better. Further downloads will be available here over time.
