//!  A framework to compute the shape as seen in <br>
//! a projection plane. This is done by calculating <br>
//! the visible and the hidden parts of the shape. <br>
//! HLRBRep_PolyAlgo works with three types of entity: <br>
//! -   shapes to be visualized (these shapes must <br>
//!   have already been triangulated.) <br>
//! -   edges in these shapes (these edges are <br>
//!   defined as polygonal lines on the <br>
//!   triangulation of the shape, and are the basic <br>
//!   entities which will be visualized or hidden), and <br>
//! -   triangles in these shapes which hide the edges. <br>
//!   HLRBRep_PolyAlgo is based on the principle <br>
//! of comparing each edge of the shape to be <br>
//! visualized with each of the triangles produced <br>
//! by the triangulation of the shape, and <br>
//! calculating the visible and the hidden parts of each edge. <br>
//! For a given projection, HLRBRep_PolyAlgo <br>
//! calculates a set of lines characteristic of the <br>
//! object being represented. It is also used in <br>
//! conjunction with the HLRBRep_PolyHLRToShape extraction <br>
//! utilities, which reconstruct a new, simplified <br>
//! shape from a selection of calculation results. <br>
//! This new shape is made up of edges, which <br>
//! represent the shape visualized in the projection. <br>
//! HLRBRep_PolyAlgo works with a polyhedral <br>
//! simplification of the shape whereas <br>
//! HLRBRep_Algo takes the shape itself into <br>
//! account. When you use HLRBRep_Algo, you <br>
//! obtain an exact result, whereas, when you use <br>
//! HLRBRep_PolyAlgo, you reduce computation <br>
//! time but obtain polygonal segments. <br>
//! An HLRBRep_PolyAlgo object provides a framework for: <br>
//! -   defining the point of view <br>
//! -   identifying the shape or shapes to be visualized <br>
//! -   calculating the outlines <br>
//! -   calculating the visible and hidden lines of the shape. <br>
//!   Warning <br>
//! -   Superimposed lines are not eliminated by this algorithm. <br>
//! -   There must be no unfinished objects inside the shape you wish to visualize. <br>
//! -   Points are not treated. <br>
//! -   Note that this is not the sort of algorithm <br>
//!   used in generating shading, which calculates <br>
//!   the visible and hidden parts of each face in a <br>
//!   shape to be visualized by comparing each <br>
//!   face in the shape with every other face in the same shape. <br>
