Alpha mapping
From HandWiki
Short description: Technique in 3D computer graphics
Alpha mapping or transparency mapping is a technique in 3D computer graphics involving the use of texture mapping to designate the amount of transparency/translucency of areas in a certain object.[1][2]
The alpha map is often encoded in the alpha channel of an RGBA texture used for coloring, but can also exist as a standalone greyscale or coloured texture.[1][2] An alpha map is often used in conjunction with a textured flat surface as part of billboarding.[1]
