The application

Every operator,nothing to build

The Ubuntu 22 build from the VisIt project, with every plot and operator in it.

Plots and operators

Pick a plot, stack operators beneath it, and the pipeline rebuilds on every database you open.

Slice, clip and query

Cut through the mesh, pull a subset out of it, and query the value at a point or along a line.

Volume rendering

Iso-surfaces, transfer functions and ray casting over scalar fields, coloured how you like it.

Cycles and camera

Step through the cycles, keyframe the camera, and write the sequence out as frames or a movie.

Expressions and Python

Derive a new field from the ones you have, then drive the entire session from a Python script.

Any mesh

Structured, unstructured, AMR and point meshes, with material and species subsetting built in.

The session

A Linux desktop in the tab, with the panel kept so windows can move.
