PV-WAVE, from Visual Numerics, Inc., is an array oriented fourth generation programming language used by engineers, scientists, researchers and business analysts to build and deploy visual data analysis applications. These applications let users manipulate and visualize complex or extremely large technical datasets to detect and display patterns, trends and anomalies along with other vital information. In the latest release of PV-WAVE, the VTK toolkit has been integrated to make all of its functionality available to PV-WAVE users. The two products complement each other exceptionally well. PV-WAVE excels at data access, data manipulation, numerical algorithms, data filtering, user interface development and many interactive 2D graphical tasks while the Visualization toolkit provides the tool for creating complex, powerful 3D visualizations. Together they provide a simple and fast way to build tools for Visual Data Analysis.
