Page "Parallel rendering" Paragraph 1

There are two, often competing, reasons for using parallel rendering.

Performance scaling allows frames to be rendered more quickly while data scaling allows larger data sets to be visualized.

Different methods of distributing the workload tend to favor one type of scaling over the other.

There can also be other advantages and disadvantages such as latency and load balancing issues.

The three main options for primitives to distribute are entire frames, pixels, or objects ( e. g. triangle meshes ).
