Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In computer graphics, texture splatting is a method for combining different textures. The method works by applying an alphamap to the higher levels, revealing the layers underneath where the alphamap is partially or completely transparent. The term was coined by Charles Bloom.Since texture splatting is commonly used for terrain rendering in computer games, various optimizations are required. Because the underlying principle is for each texture to have its own alpha channel, large amounts of memory can easily be consumed. As a solution to this problem, multiple alpha maps can be combined into one texture using the red channel for one map, the blue for another, and so on. This effectively uses a single texture to supply alpha maps for four real-color textures. The alpha textures can also use a lower resolution than the color textures.
