'''Parallel rendering''' is used to improve the performance of [[computer graphics]]. The Renderingrendering of graphics requires high computational resources for complex objects like [[medical visualization]], [[iso-surface generation]] orand some of the [[CAD]] applications. The traditionalTraditional methods like Ray[[ray-Castingcasting]], [[3D Texturestexture]]s, etc that are used for such applications., work terriblyextremely slow in simple machines.
To improve upon the performance of such applications Parallel Rendering can be used. Parallel Rendering isrendering dividingdivides the work to be done and processingprocesses it in parallel. For example, if we have a ray-casting application, we would be sending 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 thing and then composite the results. This is parallel rendering.
Parallel Renderingrendering can be used in graphics intensive applications to visualize the data more efficiently by adding some resources like more machines etc.
There is an open source software chromium (http://chromium.sourceforge.net) that provides parallel rendering mechanism for existing applications.
