34 | //! A framework for filtering the computation |
35 | //! results of an HLRBRep_Algo algorithm by extraction. |
36 | //! From the results calculated by the algorithm on |
37 | //! a shape, a filter returns the type of edge you |
38 | //! want to identify. You can choose any of the following types of output: |
39 | //! - visible sharp edges |
40 | //! - hidden sharp edges |
41 | //! - visible smooth edges |
42 | //! - hidden smooth edges |
43 | //! - visible sewn edges |
44 | //! - hidden sewn edges |
45 | //! - visible outline edges |
46 | //! - hidden outline edges. |
47 | //! - visible isoparameters and |
48 | //! - hidden isoparameters. |
49 | //! Sharp edges present a C0 continuity (non G1). |
50 | //! Smooth edges present a G1 continuity (non G2). |
51 | //! Sewn edges present a C2 continuity. |
52 | //! The result is composed of 2D edges in the |
53 | //! projection plane of the view which the |
54 | //! algorithm has worked with. These 2D edges |
55 | //! are not included in the data structure of the visualized shape. |
56 | //! In order to obtain a complete image, you must |
57 | //! combine the shapes given by each of the chosen filters. |
58 | //! The construction of the shape does not call a |
59 | //! new computation of the algorithm, but only |
60 | //! reads its internal results. |
61 | //! The methods of this shape are almost identic to those of the HLRBrep_PolyHLRToShape class. |
