Hi! I was wondering if someone could point out where can I find information about few topics :

opengl’s mathematical representation of images.
Maths behind GL_MODELVIEW and GL_PROJECTION.

Thanks

Hi !

Many books have good information about it.

You could also have a peek at the opengl spec. (you can download it from this website), it also has lots of information.

And you could download Mesa (www.mesa3d.org) and look at the source code.

What does ‘opengl’s mathematical representation of images’ mean?

OpenGl does not have support for any images at all, it can just get and put raw image data, if you want to use some kind of image format you have to do that yourself.

i thought the Computer Graphics PRINCIPLES AND PRACTICES is good at talking about the theory and princple behind the opengl.
