Mesa


Mesa is a highly portable 3D graphics library which provides an interface similar to Silicon Graphics' OpenGL. Like most highly portable software, Mesa is not as fast as hardware-specific code, and it certainly doesn't stand a chance against hardware-accelerated graphics on an SGI machine. However, on the suns in the andrew cluster it can still render at a fairly respectable speed, and most importantly, it's free.
You should check out the Mesa home page for more information. There is also online OpenGL documentation.
