  1. I am considering developing a Stellar 7 -style game, and I need 3D
  2. projection routines for that. I have read that a basic projection
  3. formula would be:
  4. Xscreen = (D*X)/(Z+D)
  5. Yscreen = (D*Y)/(Z+D)
  6. where X, Y and Z are the 3D coordinates and D is the distance of the
  7. eye from the screen. However, these routines tend to elongate objects
  8. in the distance. Is there any way to use more realistic formulas?
