40 | //! reconstruct complex topological objects as Faces |
41 | //! or Solids. |
42 | //! * Loop is the composite topological object of |
43 | //! the boundary. Wire for a Face. Shell for a Solid. |
44 | //! * LoopSet is a tool describing the object to |
45 | //! build. It gives an iteration on Loops. For each |
46 | //! Loop it tells if it is on the boundary or if it is |
47 | //! an interference. |
48 | //! * LoopClassifier is an algorithm used to test |
49 | //! if a Loop is inside another Loop. |
50 | //! The result of the reconstruction is an iteration |
51 | //! on the reconstructed areas. An area is described |
52 | //! by a set of Loops. |
53 | //! A AreaBuilder is built with : |
54 | //! - a LoopSet describing the object to reconstruct. |
55 | //! - a LoopClassifier providing the classification algorithm. |
