My friend is preparing an astronomy lecture and asked me to produce a video
of a saturn flyby, so I dusted of an old saturn I did, but I wasn't
satisfied with the rings.
The original version used a spherical pattern and a colour_map to do the
rings, but it looked flat and artificial.
Here is the latest version. The new version uses three images from Bjorn
Jonsson's excellent website (http://www.mmedia.is/~bjj/) for the rings. The
problem I had was that POV has no innate way of mapping an image_map
radially onto a flat plane (ie the rings). I solved this by writing some
functions that map a radial coordinate onto the linear image_map. The new
rings show far more detail and look much more realistic. If anyone knows an
easier way please tell me!
I have posted the source and image files into p.b.s-f
Now the animation is done, my friend has asked if I can do another of
Jupiter!
