Projection Parameters

Each of the parameters uses either the world-coordinate (WC) or viewing reference-coordinate (VRC) system.

  • The View Reference Point (VRP) is the point (WC) from which the camera is viewing the 3D geometry.
  • The View Plane Normal (VPN) is the normal (WC) ...
  • The View Up Vector (VUP) is the vector (WC) that defines the orientation of the camera (i.e. which way is up)
  • The Projection Reference Point (PRP) is the point (VRC) ...
  • The Viewing Window is the rectangle (VRC) that defines the size of the 2D window upon which the 3D geometry will be projected.
  • The projection type can be either parallel or perspective
