MATLAB is a high-performance language for technical computing. It integrates computation, visualization, and programming in an easy-to-use environment where problems and solutions are expressed in familiar mathematical notation. Read More »


Grace is a WYSIWYG tool for 2-D plots of numerical data. It runs under various flavors of Unix with X11 and M*tif (LessTif or Motif). It combines the convenience of a graphical user interface with the power of a scripting language. The combination allows grace to perform sophisticated calculations or to perform automated tasks.

ParaView is an open-source, multi-platform data analysis and visualization application. Data exploration can be done interactively in 3D or using batch processing. It was developed to analyze extremely large datasets using distributed memory computing resources and run on supercomputers well as on laptops. Read More »

VisIt - 3D Scientific Visualization

VisIt is a point-and-click 3D scientific visualization application that supports most common visualization techniques (e.g., isocontouring and volume rendering) on structured and unstructured grids. Due to its distributed and parallel architecture, VisIt is able to handle very large datasets interactively. In addition, VisIt is extensible, allowing users to add data loaders or additional analysis tools to VisIt. The NERSC Analytics Group has developed extensions to VisIt to support NERSC user applications, and coordinates with the VisIt development team to add these extensions to the main VisIt development code branch.
