The 3D Texture Extension
The 3D texture extension, EXT_texture3D, defines 3-dimensional texture mapping and in-memory formats for 3D images, and adds pixel storage modes to support them.
3D textures can be thought of as an array of 2D textures, as illustrated in Figure 6-1.
Figure 6-1 : 3D Texture
A 3D texture is mapped into (s,t,r) coordinates such that its lower left back corner is (0,0,0) and its upper right front corner is (1,1,1).
