VisIt
VisIt is an Open Source, interactive, scalable, visualization tool. It can be run interactively, but one can also use scripts. Tutorials can be found here. It is provided for Linux, Windows, and OS X and you can download it here. Installation is straightforward.
Converting data to HDF5
You can convert your data into HDF5 format, which can read by Visit. The data will be stored in a binary *.h5 and a description file *.xmf will specify the data content in XML format.

Visualising examples
Optical surface
- add > contour > taur & log
- value = 1
- single color = grey
- opacity = 50%
Temperature excess
- add > pseudocolor > taur & log, color = orange
- operations > selection > threshold > min=0.1
- operations > slicing > isosurface > tt, value = 1.05
Mach number
- add > contour > mach number, value = 1, single color = blue
Vorticity
- add > pseudocolor > taur & log, color = RdPu
- operations > selection > threshold > min=0.01
- operations > slicing > isosurface > vorticty, value = 3
Volume rendering
- add > volume > vorticity
Important!!! Uncheck: Sample data onto regular grid, otherwise volume rendering won't work.
- splatting: > 1d transfer function > min & max, opacity: gauss
- silvr: > 1d transfer function > attentution 50%, opacity linear increasing
- raycastin: kernel based (slow!)
