If you're looking to just work with 3D yourself, there's always straight

Hello Marc-antoine:
All you need to do is write the shaders and load them into the GPU via
OpenGL's GLSL API.
OpenGL and Microsoft DirectX/3D have been leapfrogging each other for the
past 10 years and the shader capabilities of each are pretty comparable.
Because of OpenGLs extension mechanism OpenGL will sometimes get a feature
before DirectX/3D but unfortunately the acquiring the Pixel Format /
Rendering Context (roughly equivalent to the capability-bits in DirectX/3D)
in OpenGL has gotten really ugly because of that.

Hello Michal:

I implemented the OpenGL 2.0 or greater version of the shader functions so
you will likely need to install OpenGL 2.0 or greater drivers for your video
card. It looks like you are running the software-only OpenGL drivers that
come with Linux.
In the initialize procedure I do the following check for the required OpenGL
functions:
if not (GL.respond_to?('CreateProgram') and
GL.respond_to?('CreateShader') and
GL.respond_to?('ShaderSource') and
GL.respond_to?('CompileShader') and
GL.respond_to?('AttachShader') and
GL.respond_to?('LinkProgram') and
GL.respond_to?('DeleteShader') and
GL.respond_to?('DeleteProgram'))
puts('Error - The program has terminated because the environment does
' +
'not support OpenGL 2.0 or greater GLSL shaders.')
exit
end
In theory, if your MESA / SGI driver supported shaders through ARB
extensions (like some earlier OpenGL's did) instead of as built in functions
(like OpenGL 2.0+ in the recent ATI, Nvidia and Intel drivers) then you
could modify this section and other sections of code to use the alternate
(i.e. older) function names. However, I do not believe your drivers support
shaders at all.

Yes, there are some ARB extensions listed.
The problem is that Intel does not do special driver for Linux, their
hardware is supposedly supported by X11/Mesa and the proprietary
drivers for ATI/nVidia cards simply do not work (tried with recent
cards about half an year ago).
Running a demo is as far as I got in using OpenGL so I guess I will

It supports fragment and vertex programs. I do not know it that is
sufficient but I think FireGL V3350 should support some shading.

Sorry to hear that. I do most of my work in Windows. I just booted my
desktop into Mint Linux 7 which already had the Nvidia 3D drivers installed
then installed ruby 1.8.7, glut, ruby-opengl and ran the
gears_with_shaders.rb file just fine. I have had the best success with Nvidia
under Linux. Even the Geforce Go 6150 in my old HP tx1000 laptop supports
OpenGL 2.1 in Mint Linux 8. I have had some success with ATI in Linux but it
varies greatly for different models and from distro-to-distro. I'd heard
that the Intel x3100 IGP and later chipsets were supposed to support OpenGL
2.0+ but have not had direct experience with them.

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.
