OpenDX is a uniquely powerful, full-featured software package for the visualization of scientific, engineering and analytical data.
The GUI has a wide variety of interactors, both direct and indirect. Direct interactors allow you to directly manipulate images (e.g. rotate or zoom). Indirect interactors (dials, switches, buttons, sliders) enable you to control various aspects of your visualization.
OpenDX provides hundreds of functions. To make the system easier to use, these functions have been grouped into powerful, polymorphic modules. For example, "Compute" does the work of dozens of individual functions. It directly solves arbitrary algebraic and trigonometric equations, as well as recasts your data.
