[MUD-Dev2] TECH: The maths behind 3D rendering ?

[Ricky C]

I wholeheartedly recommend this book: http://amzn.com/1592730051

Part 2 starts at the basics and builds up a 3D engine from scratch, and
continues into lessons on AI, collision detection, and eventually builds up
to a shooter game. There is no DirectX or OpenGL in this book, no graphics
libraries at all. The entire thing is handwritten, and the result is
amazing.

As long as you have knowledge of the Java language, I highly recommend this
book for exactly what you're trying to do.
