Perspective projection

I've always been interested in Computer Graphics. This area of computer science unites most of the things I´m interested in. From pure maths to algorithm analysis, and software engineering, if you want to be a good graphics programmer, you need to master of this fields of knowledge.

The purpose of this post is to provide a set of interesting links about perspective projection. This concept is absolutely essential to understand modern graphics, especially 3D game graphics. Thanks to APIs like OpenGl or DirectX, you don´t have to program your own projection, but you need to understand what is going on under the hood to be able to make the most out of it.

• Siggraph Perspective Viewing Projection. This is a rather mathematical explanation, but is there any other way.
• Client Management Systems, computer graphics introduction. No maths at all, so this is a good starting point.

Enjoy!!!
