<BLOCKQUOTE>
|
|
This effect applies additive specular highlights at fragment level (instead
|
|
of OpenGL's vertex-level lighting) by using a cube map and reflective texgen.
|
|
A texture matrix is computed to rotate the cube map automatically; this makes
|
|
the specular effect consistent with respect to view direction and light position.
|
|
The user can choose which light should be used to compute the texture matrix.
|
|
This effect requires the GL_ARB_texture_env_add extension and one of the cube map
|
|
extensions (GL_EXT_texture_cube_map, GL_ARB_texture_cube_map or OpenGL v1.3).</BLOCKQUOTE>
