== Subdivision of work ==

Parallel rendering divides the work to be done and processes it in parallel. For example, if we have a non-parallel ray-casting application, we would send rays one by one to all the pixels in the [[Viewing frustum|view frustum]]. Instead, we can divide the whole frustum into some x number of parts and then run that many threads or processes to send rays in parallel to those x tiles. We can use a cluster of machines to do such a thing and then composite the results. This is parallel rendering.

==Non-interactive parallel rendering==

Line 38:

Parallel rendering can be used in graphics intensive applications to visualize the data more efficiently by adding resources like more machines.

== [[Open-source software|Open source]] applications ==

The open source software package Chromium (http://chromium.sourceforge.net) provides a parallel rendering mechanism for existing applications. It intercepts the [[OpenGL]] calls and processed them, typically to send them to multiple rendering units driving a [[video wall|display wall]].
