(Sorry if my mails look strange, I'm using this bizarre webmail)
I'm making this solar system simulator (is that everybody's first 3D job?), but
I'm just a novice with 3D, so maybe you could help me out with a couple of
things.
http://www.jobe.nu/pub/Solar3D.htm
(I had to change the interaction model because of the setmouse xtra not being
SW safe, so it's not as intuitive as it should be, but you'll be able to get an
idea)
(One cool thing is that the stars have "real" positions and magnitudes,
downloaded from the Simbad astronomical database)
I'd like the planets' orbits to be displayed. What's an efficient way to do
this? Having 9 toruses seem a bit heavy. Or could a LOD modifier do a good job
on those? Maybe 3D sprites that plot the orbit?
Also, I want a shader that is totally non-responsive to lights - no ambient,
specular or reflections - just the "light" coming from the emissive property
should affect the model. I've tried setting every light-related property of the
shader to 0 or rgb(0,0,0), but the objects are still enlighted by lights around
them. How do I fix that?
