I have a need to display 3D wireframe graphics and have used code from Keith Vetter's Octabug, 3D to 2D transformation program. This works ok but it creates an illusion of perspective (parallel lines converge). I am looking for TCL code which works similiar to this but without the distortion. In summary I need to "map 3d coordinates to a 2d plane based upon a defined eye position".

Anybody know of code or algorithms available?
