Hi Joseph, I don't see it. Your example has from=(0,0,2) and to=(0,0,1). Change "to" to (0,0,0.1) or (0,0,1.9), and there's no difference in clipping (or the view in general), even though there are connection lines in the z=1 plane.
Randy Joseph Young: |Thanks very much for your reply. After I sent my question to the list, I |too got into the code - particularly camera.c - to see what was going on. |Your email confirmed what I had found. | |If I understand your reply correctly, I have one minor difference |concerning the location of the projection plane and front clipping plane. I |believe the projection plane runs right through the "To" point and that it |also acts as the front clipping plane. | |To confirm this, I set up a small experiment where I positioned a simple |2x2x2 cube on the origin and viewed in perspective with a "View Angle" of |90 degrees and with the X resolution = Y resolution (this means all half |angles are 45 degrees which makes it easy to determine what the final |projection should look like). If you then generate a perspective view the |cube (connections) using from = (2,0,2) and to = (1,0,1), the front cube |face lies on the projection plane and it should consume all of the rendered |image window, due to the location of the viewer and the 90 degree view |angle. And this does indeed occur. I've inserted the small net in the email |if you wanted to try it. -- Randall Hopper (mailto:[EMAIL PROTECTED]) Lockheed Martin Operation Support EPA Scientific Visualization Center US EPA N127-01; RTP, NC 27711
