};

Constants

Constant Description
CNMAP_DEFAULT Set default flags.
CNMAP_CHANNEL_RED Selects which channel to use as the height. Luminance is the average of R, G, and B.
CNMAP_CHANNEL_GREEN  
CNMAP_CHANNEL_BLUE  
CNMAP_CHANNEL_ALPHA  
CNMAP_CHANNEL_LUMINANCE  
CNMAP_MIRROR_U Selects mirroring semantics for scanline references. Otherwise defaults to wrap.
CNMAP_MIRROR_V  
CNMAP_MIRROR Same as both CNMAP_MIRROR_U and CNMAP_MIRROR_V.
CNMAP_INVERT_SIGN Inverts the sign of the computed normal vector.
CNMAP_COMPUTE_OCCLUSION Computes a crude occlusion term and stores in the resulting alpha channel.
