I hope you don't find this misplaced; pardon me, please, if you do.
I'm working on a project of modeling the stars of the constellations in 3-D; not for their positions relative to Earth, but relative to any given person being at 0,0,0.
Is there a simple formula for this? ...or better yet, do you know anyone who has them on the net or in a book?
Clarification: I see that I too hastily posted the question. 0,0,0 would be Earth. The figure for 'x' would need to be the distance from Earth, with y and z being taken from RA and DEC...is that right?
If we use the stars of Orions belt as an example, can you help me put them to x,y,z?
