OnlineHelp/ParaView

ParaView is a scalable, open-source visualization application. The application runs on a wide variety of platforms, ranging from a single-processor desktop machine to multi-processor shared-memory supercomputers or clusters of computers. When run in a parallel environment, ParaView can process very large data in a wide variety of data formats (structured and unstructured, time varying and static).

ParaView provides a comprehensive suite of visualization algorithms and supports many different file formats for both loading and exporting datasets. This application is extensible, so new algorithms can be easily added. ParaView 3 is more quantitative and data-centric than previous versions of ParaView, providing more plotting and charting functionality as well as allowing easier access to the data values underlying the visualization.
