Reduction of a portion of an analytic surface to a mesh of polygons, or of a portion of an analytic curve to a sequence of lines.
A texture element. A texel is obtained from texture memory and represents the color of the texture to be applied to a corresponding fragment. See also fragment.
A one- or two-dimensional image used to modify the color of fragments produced by rasterization. See also rasterize.
- texture mapping
The process of applying an image (the texture) to a primitive. Texture mapping is often used to add realism to a scene. For example, you could apply a picture of a building facade to a polygon representing a wall. See also texture.
- texture matrix
The 4x4 matrix that transforms texture coordinates from the coordinates that they're specified in to the coordinates that are used for interpolation and texture lookup.
A warping of space. In OpenGL, transformations are limited to projective transformations that include anything that can be represented by a 4x4 matrix. Such transformations include rotations, translations, (nonuniform) scalings along the coordinate axes, perspective transformations, and combinations of these.
A polygon with three edges. Triangles are always convex.
