0046 //! to remove Hidden lines on Shapes with Triangulations.
0047 //! A framework to compute the shape as seen in
0048 //! a projection plane. This is done by calculating
0049 //! the visible and the hidden parts of the shape.
0050 //! HLRBRep_PolyAlgo works with three types of entity:
0051 //! -   shapes to be visualized (these shapes must
0052 //! have already been triangulated.)
0053 //! -   edges in these shapes (these edges are
0054 //! defined as polygonal lines on the
0055 //! triangulation of the shape, and are the basic
0056 //! entities which will be visualized or hidden), and
0057 //! -   triangles in these shapes which hide the edges.
0058 //! HLRBRep_PolyAlgo is based on the principle
0059 //! of comparing each edge of the shape to be
0060 //! visualized with each of the triangles produced
0061 //! by the triangulation of the shape, and
0062 //! calculating the visible and the hidden parts of each edge.
0063 //! For a given projection, HLRBRep_PolyAlgo
0064 //! calculates a set of lines characteristic of the
0065 //! object being represented. It is also used in
0066 //! conjunction with the HLRBRep_PolyHLRToShape extraction
0067 //! utilities, which reconstruct a new, simplified
0068 //! shape from a selection of calculation results.
0069 //! This new shape is made up of edges, which
0070 //! represent the shape visualized in the projection.
0071 //! HLRBRep_PolyAlgo works with a polyhedral
0072 //! simplification of the shape whereas
0073 //! HLRBRep_Algo takes the shape itself into
0074 //! account. When you use HLRBRep_Algo, you
0075 //! obtain an exact result, whereas, when you use
0076 //! HLRBRep_PolyAlgo, you reduce computation
0077 //! time but obtain polygonal segments.
0078 //! An HLRBRep_PolyAlgo object provides a framework for:
0079 //! -   defining the point of view
0080 //! -   identifying the shape or shapes to be visualized
0081 //! -   calculating the outlines
0082 //! -   calculating the visible and hidden lines of the shape.
0083 //! Warning
0084 //! -   Superimposed lines are not eliminated by this algorithm.
0085 //! -   There must be no unfinished objects inside the shape you wish to visualize.
0086 //! -   Points are not treated.
0087 //! -   Note that this is not the sort of algorithm
0088 //! used in generating shading, which calculates
0089 //! the visible and hidden parts of each face in a
0090 //! shape to be visualized by comparing each
0091 //! face in the shape with every other face in the same shape.
