Viewing Reference Coordinates (VRC)--2

• Viewing reference coordinates (VRC) in summary:

  • an origin at the VRP

  • an n-axis along the VPN

  • a v-axis along the projection of the VUP onto the view plane

  • a u-axis, determined by "right hand rule": u x v = n

• View volume intersects the view plane in a view window.
  
  

• View window is described by maximum and minimum values of u and v.
