Povray for Science

The Persistence of Vision Raytracer is a high-quality, totally free tool for creating stunning three-dimensional graphics. It is available in official versions for Windows, Mac OS/Mac OS X and i86 Linux. The source code is available for those wanting to do their own ports.

Can it be used for science? Well, at least in astronomy many observers and even theorists use so-called "toy-models" to visualize their models. A "toy model" is something that is not strictly scientific but still based upon - "heavily simplified" - scientific assumptions. You want to imagine the 3D geometry of the latest star forming region you observed? You want to communicate the results of a hydrodynamical calculation to non-imaginative observeres without calling the radiative transfer specialist in advance? Povray is your tool!

Collapse of a Molecular Cloud

One of the great advantages of povray is that it can easily render complete animation sequences. As an example please find here the collapse of a molecular cloud to a protostar including its accretion disk.

Formation of a Planet

Another animation - here is what happens a little later than in the animation above: The formation of a planet in a circumstellar disk.
