Samples of Some Things VisIt Can Do

  • Plotting Methods—VisIt contains a rich set of visualization methods for visualizing scientific data.
  • Operators—VisIt supports various operators to visualize data within a three-dimensional volume. These include displaying fields on surfaces within a volume (cone, sphere, plane, and more), removing portions of the three-dimensional volume (clip), displaying fields within a localized region (onion-peel), and displaying portions of the volume that meet specific criteria.
  • Data Exploration—VisIt allows the ability to provide quantitative as well as qualitative information from a scientific data set.
  • Graphical User Interface (GUI)—VisIt has a powerful, yet easy-to-use graphical user interface.

Plotting Methods

The contour plot (left) is used to display lines of constant temperature on a planar slice through a simulation of a gas-burning furnace. The pseudocolor plot (right) is used to map temperature to color on the same planar slice.


The contour plot (left) is used to display surfaces of constant value through a three-dimensional volume. The volume plot (right) allows the potential to visualize all the data within a three-dimensional volume by mapping scalar values to an opacity and color value.


The vector plot allows the ability to visualize vector fields by placing arrow glyphs within the vector field indicating direction and magnitude. The first image shows vectors on a planar slice of an air flow over a box. The second image is a close up showing the turbulant flow directly behind the box.


The subset plot is used to display different parts of an assembly. Portions of the assembly can be selectively turned on and off. The first image shows an entire crash impact dummy, while the second image shows only the hips and upper body.
