What Libraries do I require to use ARB-extensions such as ARB-Multitexturing
I read somewhere they are implemented in the latest opengl lib and header files but where can I download these?
thx in advance Jan Bop
The driver provides the pointers to the extensions. Update your driver and get the latest header files from http://oss.sgi.com/projects/ogl-sample/registry.
See the OpenGL Programming Guide (e.g. wglGetProcAddress, glXGetProcAddress, chapter 14 Extension to the Standard)
Here’s an example (for glMultiDrawElements) that might help.
Sorry about formatting … some white space is removed when posting … not sure why.

Okay … so maybe posts are limited in size. I’ll send example if you e-mail me.

Okay … have no idea what’s up with posting. I tried 
A simple way to get extensions (and newer core versions than 1.1 on windows) is using an extension loading library such as glew. Quick and easy.
There are several others available that do more or less the same thing.
thx for reply I will look into it
