Analemma Visualisation: 3D Graphics & Visualisations

[Himanshu]

Recently I read about http://en.wikipedia.org/wiki/Analemma" on the internet but I cannot visualise their formation depending upon the causative factors such as obliquity, eccentricity, and the angle between the apse line and the line of solstices. I wanted to know if someone knows about 3D visualisations and graphics anywhere on the net.

It is very difficult to find on the internet a 3d simulation program of analemma but you can try to make one of your own using Math programs.
If that helps i recommend two programmes of 2d analyses of the analema.
