Preface

One of the most interesting features introduced to Direct3D in DirectX 6 was multiple texturing.

In previous versions of DirectX, the texture mapping phase of the Direct3D pixel pipeline had only involved fetching texels from a single texture. DirectX 6 introduced the concept of a texture operation unit.

Get the source here. To compile the source, take a look at "The Basics" Tutorial. To switch between the examples use the #defines at the beginning of the source:

...
// Multitexturing using Colour operations
#define DARKMAPPING  1
#define ADARKMAPPING 2
#define DIFFUSECOLOR 3
#define DARKDIFFUSE  4

// Multitexturing using Alpha operations
#define MODULATEALPHA 5
#define BLENDWFRAME 6

// The switch
#define TM 5
...
