    orthographic parallel projection

    I am trying to draw a bezier surface using orthographic paralle projection to view the surface. VRP (0,0,0) and VPN is (0,0,-1).

    I'm just trying to see where my eyes are located and in which direction Im viewing the object

    Is the following figure correct? My eyes are located at VRP (0,0,0) (red circle) looking at the -z side. VPN is in green. Object is yellow.

    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
