The nVIdia drivers may have better 3D support but no matter what I do
I cannot set up rotated display properly on them. The glue for binary
ATI drivers did not even compile for me.

The mesa library should support OpenGL 2.1 since version 7 but it
seems that support for different features in hardware accelerated
drivers varies per chipset due to hardware limitations or some
features may be simply not implemented for some hardware.

I would also think that higher level libraries like Ogre or
CrystalSpace would make a better job at isolating the developer from
these hardware and driver differences than raw OpenGL.

I don't have such system at hand either, only i945G/GM (something like
GMA900 or GMA950) here.

Thanks

I tested Ruby-processing and I saw good 3D samples made thanks to
OpenGL.

But I did'nt find people using it to do something.
I just found some samples using free-context, but it's not 3D.

Does someone use Ruby-Processing to made something greater than a 15
seconds technical demo ?
