FogVertexMode = int(mode)
VALID ENUMERANTS
mode: None, Exp, Exp2, Linear
DESCRIPTION
Specify whether to use the fog coordinate or fragment depth as distance value in the fog computation.
See the GL_FOG_COORDINATE_SOURCE description on the OpenGL glFog manual page for details. See the D3DRS_FOGVERTEXMODE render state description for DirectX 9.
The standard reset callback sets the FogVertexMode state to int(GL_FRAGMENT_DEPTH_EXT).
