Learn how to do this in GLSL with OpenGL. Related posts:

A nice looking tutorial, and you will be seeing grass, mud, rocks and sand, but a bad texture and you will see just a bunch of colors. Lets add a nice texture to our terrain shall we?

This means that if you pass the texture id to the shader, you can replicate all the texturing done in OpenGL. Related posts:

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.

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!

This scaled down version of the texture, makes for nicer, smoother looking textures.

OpenGL has some texture coordinate methods for generic texturing.

Texturing is the art of drawing an image on top of a 3D object and is the core behind all 3D applications. Could you imaging Half Life 2 coming out, and the characters looked like store mannequins?
