Texture Mapping

Texture Mapping. To add surface details…. More polygons (slow and hard to handle small details) Less polygons but with textures (much faster). World of Warcraft , Blizzard Inc. Advantages. Texture mapping doesn’t affect geometry processing, such as transformation, clipping, projection, …

Texture Mapping

Texture Mapping. Until now, colors and shades determined the vertices color Texture is the characteristic physical structure given to an object by the size, shape, arrangement of its parts By texture mapping we apply image data to a geometric primitive. Basic strategy.

Texture Mapping

Texture Mapping. Introduction. Textures are simply rectangular arrays of data. Ex. Color, luminance, alpha, normal … The individual values in a texture array are called texel. In OpenGL, the length and width of the texture array must be the power of 2. Forward Mapping. Backward Mapping.
