Questions tagged [textures]
Textures are series of images used in computer graphics to associate locations on a visible surface with varying values. This association is typically done by mapping locations on the texture (usually two-dimensional, but other dimensions and types of textures exist) to locations on the rendered surface. Filtering is often used to smooth away aliasing when sampling values from the texture, usually involving multiple images within a texture called mipmaps.
