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