//! In order to have the precision required in
//! industrial design, drawings need to offer the
//! possibility of removing lines, which are hidden
//! in a given projection. To do this, the Hidden
//! Line Removal component provides two
//! algorithms: HLRBRep_Algo and HLRBRep_PolyAlgo.
//! These algorithms remove or indicate lines
//! hidden by surfaces. For a given projection, they
//! calculate a set of lines characteristic of the
//! object being represented. They are also used
//! in conjunction with 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 lines
//! of the visualized shape in a plane. This plane is the projection plane.
//! HLRBRep_Algo takes into account the shape
//! itself. HLRBRep_PolyAlgo works with a
//! polyhedral simplification of the shape. When
//! you use HLRBRep_Algo, you obtain an exact
//! result, whereas, when you use
//! HLRBRep_PolyAlgo, you reduce computation
//! time but obtain polygonal segments.
