//! A framework for filtering the computation
|
|
//! results of an HLRBRep_Algo algorithm by extraction.
|
|
//! From the results calculated by the algorithm on
|
|
//! a shape, a filter returns the type of edge you
|
|
//! want to identify. You can choose any of the following types of output:
|
|
//! - visible sharp edges
|
|
//! - hidden sharp edges
|
|
//! - visible smooth edges
|
|
//! - hidden smooth edges
|
|
//! - visible sewn edges
|
|
//! - hidden sewn edges
|
|
//! - visible outline edges
|
|
//! - hidden outline edges.
|
|
//! - visible isoparameters and
|
|
//! - hidden isoparameters.
|
|
//! Sharp edges present a C0 continuity (non G1).
|
|
//! Smooth edges present a G1 continuity (non G2).
|
|
//! Sewn edges present a C2 continuity.
|
|
//! The result is composed of 2D edges in the
|
|
//! projection plane of the view which the
|
|
//! algorithm has worked with. These 2D edges
|
|
//! are not included in the data structure of the visualized shape.
|
|
//! In order to obtain a complete image, you must
|
|
//! combine the shapes given by each of the chosen filters.
|
|
//! The construction of the shape does not call a
|
|
//! new computation of the algorithm, but only
|
|
//! reads its internal results.
|
|
//! The methods of this shape are almost identic to those of the HLRBrep_PolyHLRToShape class.
