Tool: VisIt

Visit is a parallel visualization and graphical analysis tool for viewing scientific data on Unix and Windows machines. It is completely free and is available for download along with the source code.
It is developed at the LLNL to analyze the results of the terascale simulations.

It can be used to visualize scalar and vector fields defined on unstructured meshes and its prime significance is of its ability to treat both 2d and 3d models equally well.

The tool can be downloaded here and the rich features that it can provide can be found here.

Following are the screenshots of the tool being used to analyze data of a aerodynamics model.

Different plots ( contour, psuedocolor, volume, vector, subset, molecule, label plots, etc ) that are provided by the visualization tool, VisIt, allow users to input data in various formats. Different file formats that the tool can read are found here. The important thing is that it can read image data as well and plot contour information based on the user requirements to allow analyze images. And the lable plot that the tool provides allows users to tag different objects within the input model and then perform analysis on them.
