19 | ---Purpose: This algorithm provides algorithms to computes |
20 | -- transitions when many interferences occurs at the |
21 | -- same place on a shape. |
22 | -- |
23 | -- An interference is an intersection on a shape (i.e |
24 | -- a vertex on an edge or an edge on a face) with |
25 | -- data about the transition (how the shape is |
26 | -- crossing the boundary where the intersection |
27 | -- occurs). |
28 | -- |
29 | -- There are three algorithms to process |
30 | -- interferences : |
31 | -- |
32 | -- * EdgeFaceTransition : To process interferences on |
33 | -- an adge crossing other edges on the boundary of a |
34 | -- face. |
35 | -- |
36 | -- * EdgeSolidTransition : To process interferences |
37 | -- on an edge crossing faces and edges on the |
38 | -- boundary of a solid. |
39 | -- |
40 | -- * FaceSolidTransition : To process interferences |
41 | -- on a face crossing other faces on the boundary of |
42 | -- a solid. |

44 | -- This package relies on the TopTrans package for |
45 | -- the geometric computations. |
