- I'm looking for 1, 2 and 3 point perspective formulas, to render a
- 3-dimensional scene. All I need is the formula to translate an
- (x,y,z) vector to an (x,y) projection of that, for 1, 2, and 3
- point perspective. I've already translated the object such that
- my line-of-sight is along one of the axis; I just need to know how
- to now project that into my (x,y) space so I can view it. I can
- handle all the necessary scaling, etc, to get it into my viewport.
- Simply the transformation matrix would be fine, but any discussion
- you wish to provide would also be appreciated.
-
- Thanks for any help you can give.
