Open GL for Linux... How?

Hi,
I am experimenting with linux on a freescale ARM controller, i am planning to use Open GL for my display interactions.

Did any one used Open GL? How is its performance? What foot print(size on flash/RAM) it consumes?

Thanks,
raj.

Linux has Mesa OpenGL software. It's mostly installed with XFree86 or X.org

To use 'OpenGL' : a graphics chip supporting OpenGL is necessary.

The Mesa OpenGL .....
Example 'arm' package libgl1-mesa-glx
http://packages.debian.org/lenny/libgl1-mesa-glx
Basically one file : /usr/lib/libGL.so.1.2 , 456 kB.

For OpenGL, a graphic card supporting is best option. But with the Mesa Software & Xorg, OpenGL support is supported by software. So it is not absolutely essential to have OpenGL supporting graphics card. Visit Linux DRI website page for Linux supported 3D graphic cards.

Try also using a newer ati card because they seem to have more openGL versions compared to some nVidia cards. But since you are using openSUSE be careful with the ati driver installation I ruined my distro doing it. Try patching the kernel before installing it helps and it worked perfectly after that.
