'''Parallel rendering''' is used to improve the performance of [[computer graphics]]. The rendering of graphics requires massive computational resources for complex objects like [[medical visualization]], [[iso-surface generation]], and some [[CAD]] applications. Traditional methods like [[ray-casting tracing]], [[3D texture]]s, etc., work extremely slowly in simple machines.

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 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.
