If you want to use any type of off screen rendering process, then frame buffers are probably the go for you. They allow you to render an entire scene, directly to a texture.

They are extremely fast and effecient, and are meant to supersede Display Lists. So lets use them for our terrain!

This breaks up the ground into a bunch of known images and places them on runtim. This saves us having extremely large image files for an entire map and also makes it customizable in-game.

This is where you want orthogonal projections, which are perfect for a Heads Up Display, or a menu system.

But have you ever wanted to load a movie into a 3D scene? Maybe you want to read a movie file, and display it on a quad moving around your scene. Well you can, but you have to do it frame, by frame.

Whether you want to create a weather system, some awesome fire, or just throw a million objects around randomly, they are both stimulating in a game, and fun.

In this tutorial, I will show you how to create your own sphere, which has texture coordinates included. Now you can make that solar system demo you have always wanted!

In this tutorial, I will show you how to draw a nice, round, circle.
