Line 16:

The image to the right shows an example of sort-first rendering on a [[video wall]]. Each computer in the video wall renders a portion of the viewing volume, or [[viewing frustum]], and the final image is the summation of the images on the monitors that make up the video wall. The [[speedup]] comes from the fact that graphics libraries ([[OpenGL]] for example) will [[Clipping (computer graphics)|clip]] away pixels that would appear outside of the viewing volume. This happens very early in the [[graphics pipeline]], which accelerates the rendering process by eliminating the unneeded [[rasterization]] and post-processing on primitives that will not appear anyway.

===Sort-last===

Line 24 ⟶ 22:

The image to the right shows an example of sort-last rendering. The computer in the top left corner is the [[Master-slave (computers)|master]] computer. This means it is responsible for receiving the images created by the other computers, and then compositing them into the final image, which it displays on its own monitor.
