What is MipMap? I\'ve know what it bump Mapping.
Mipmapping is a technique used to reduce the shimmering of textures. When the textures are made, 2 or more versions of that texture are made, each one being a little less detailed than the last. Then when the frame is rendered, the game uses the most detailed texture if you\'re up close to it, and the least detailed texture if you\'re far away from it.
If you\'ve played the last level of Doom 2 on the PC, then remember the horrible wall/dirt textures that shimmered every time you moved. That was before mipmapping became a must in games.
