I'm using this extension to to per pixel bump mapping and it's working ok, *except* that I can't find out how to specify the light vector.

I know how to calculate it but can't finf the opengl call needed to actually set it :)

I'd appreciate any information or pointers to a web page you might have.

Thanks.

This is not the forum for this type of questions, this is for beginner stuff.

Ok, it was a simple question on how to call the API. That seemed like a beginners question to me :)

But point taken.. I'll ask elsewhere, although I think I've found my answer already.
