说明： 介绍如何使用OPENGL渲染凹凸纹理．是学习OPENGL的纹理贴图的好例子．
(Describes how to use the OPENGL rendering bump texture. Is a good example learning the OPENGL of texture mapping.)

Description:
This demo draws a torus lit by four colored lights. One pass is performed for each light, which is attenuated per-pixel using 2 textures. Diffuse tangent space bump mapping is also performed per light, using NV_register_combiners.
Requirements:
EXT_compiled_vertex_array
EXT_texture_edge_clamp
ARB_multitexture with at least 4 texture units
NV_register_combiners
NV_vertex_program

Keys:
F1 - Take a screenshot
Escape - Quit
Space - Draw sphere of influence for each light.
1 - Disable light 1
2 - Disable light 2
3 - Disable light 3
Note: Light 0 cannot be disabled.
