I am interested in creating a 3D model of our solar system for use on the Internet (possibly with AS3 and papervision) and studied how I will deal with the coding of planetary positions. My idea was to download already-calculated positions from NASA, since position calculation seems too complicated to me. I'm not sure if I should use heliocentric or ground-oriented encoding.
I wanted to know if anyone had any experience with this. Which approach would be better? It seems that on the NASA JPL website there are positions of all the major organs of our solar system as being Earth-oriented. I see that this becomes a problem later, although when adding the Voyager and Mars Lander missions to the model?
Any feedback, comments and links are very welcome.
EDIT: I am working with a rough model that uses heliocentric coordinates, but I could not find the coordinates for all the planets in this format.
UPDATE:
I don’t have a lot of details to know, because I really don’t know what I am doing (from a cosmic point of view). I wanted to get an idea of 3D programming, and I'm interested in space. The idea was that I would make a rough simulator of the solar system with first all the planets and their orbital orbits (perhaps excluding satellites first). Perhaps there is a news aggregator and some links to news / resources and so on. The general idea would be to allow people to click and enjoy a trip to the Moon and Mars (for a starter).
