//! Summary of 3D View Mapping -- <br>
//! The view mapping transformation defines the -- <br>
//! window-to-viewport mapping of View Reference -- <br>
//! Coordinates (VRC) to Normalized Projection -- <br>
//! Coordinates (NPC). -- <br>
//! CAS.CADE supports two kinds of projection : -- <br>
//! Parallel : -- <br>
//! The Projection Reference Point (PRP) -- <br>
//! determines the direction of projection. -- <br>
//! Perspective : -- <br>
//! The projector lines converge at the -- <br>
//! Projection Reference Point (PRP). -- <br>
//! To define a view mapping transformation you -- <br>
//! must define : -- <br>
//! The Projection Type -- <br>
//! The Projection Reference Point (PRP) -- <br>
//! The Distance from Back Plane (BPD) -- <br>
//! The Distance from Front Plane (FPD) -- <br>
//! The Distance from View Plane (VPD) -- <br>
//! The Window in the View Plane. -- <br>
