For real-time 3D graphics, it has become common to use complicated heuristics (and even neural-networks) to perform anti-aliasing. [49] [50] [35]: 9.3 [16]: 5.4.2 In 3D rasterization, color is usually determined by a pixel shader or fragment shader, a small program that is run for each pixel.

3D computer graphics rely on many of the same algorithms as 2D computer vector graphics in the wire-frame model and 2D computer raster graphics in the final rendered display. In computer graphics software, 2D applications may use 3D techniques to achieve effects such as lighting , and similarly, 3D may use some 2D rendering techniques.
