3d Viewing in Computer Graphics
Two stages to the 3D to 2D transformation
- First a clipping,
- Then a projection.
The view volume of a perspective projection is the infinite volume defined by the combination of the PRP and the view window, which defines a pyramid. This can be contrasted to the view volume for a parallel projection which gives an infinite parallelepiped.
