for every point infront of the camera:

 

The tripple (x,y,z) is projected down into ((x/z),(y/z))

 

for every point behind the camera

 

The tripple (x,y,z) is projected down into ((x*z),(y*z))

 

polygons that are intersected by the camera view should be clipped and if all verticies of a polygon are out of view of the camera the polygon should be ignored.

 

I may have cracked it geometrically. I'm not sure that the circle is the correct approach but it seems to give a very good result.
Hell, I feel like a Renaissance artist. I kind of went on gut instinct with the circle. The red line is a projection plain and the blue lines are projection lines where the verticies cross the projection plain. They are then distended down into the frontal pictorial view. Like I said, I'm an amature draftsman going on gut instinct. This could be incorrect. The top drawing is a top down view and the lines must intersect the circle the width of the viewing plain while heading toward the viewer's eye.
