Texture mapping. Mapping a two-dimensional texture onto a 3D model. 1: 3D model without textures 2: Same model with textures. Texture mapping[ 1 ][ 2 ][ 3 ] is a method for mapping a texture on a computer-generated graphic. "Texture" in this context can be high frequency detail, surface texture, or color.

Texture mapping unit. In computer graphics, a texture mapping unit (TMU) is a component in modern graphics processing units (GPUs). They are able to rotate, resize, and distort a bitmap image to be placed onto an arbitrary plane of a given 3D model as a texture, in a process called texture mapping. In modern graphics cards it is implemented as ...

After 2000, perspective-correct texture mapping became widely used via floating point numbers. Perspective-correct texture mapping adds complexity, which can easily be paralleled and pipelined costing only silicon. And it adds one divide per pixel. In this respect, a graphics card has two advantages over a CPU.
Scanline rendering. Scanline rendering (also scan line rendering and scan-line rendering) is an algorithm for visible surface determination, in 3D computer graphics, that works on a row-by-row basis rather than a polygon -by-polygon or pixel -by-pixel basis. All of the polygons to be rendered are first sorted by the top y coordinate at which ...
In computer graphics, a digital differential analyzer (DDA) is hardware or software used for interpolation of variables over an interval between start and end point. DDAs are used for rasterization of lines, triangles and polygons. They can be extended to non linear functions, such as perspective correct texture mapping, quadratic curves, and ...
Terrain cartography. USGS topographic map of Stowe, Vermont with contour lines at 20-foot intervals. Terrain cartography or relief mapping is the depiction of the shape of the surface of the Earth on a map, using one or more of several techniques that have been developed. Terrain or relief is an essential aspect of physical geography, and as ...
