This simple Windows program will take the output from a PM3 semiempirical MOPAC 6 calculation and generate a POV-Ray file containing a plot of a molecular orbital. Admittedly it is somewhat basic (only supports CHNO elements), but with some manual additions to the povray file, it can still be used to produce some reasonable looking pictures.

The latest version now gives the option of generating an LScript file that will enable import of the model into LightWave 3D. The full range of LightWave modeling, animation and rendering tools are then available.

A still from an animation rendered in LightWave 7.5c to demonstrate how the model can interact with its surroundings, in this case a hypervoxel particle system which gives the appearance of a cloud of steam.
