High Quality Content by WIKIPEDIA articles! ParaView is an open source, freely available program for parallel, interactive, scientific visualization. It has a client–server architecture to facilitate remote visualization of datasets, and generates level of detail (LOD) models to maintain interactive framerates for large datasets. It is an application built on top of the Visualization Tool Kit (VTK) libraries. Where VTK is a set of libraries that provide visualization services for data, task, and pipeline parallelism, ParaView is an application designed for data parallelism on shared-memory or distributed-memory multicomputers and clusters. It can also be run as a single-computer application.
