25 | |
26 | ---Purpose: Template which defines all the services relative to |
27 | -- a MultiLine for approximation algorithms. |
28 | |
29 | uses Status from Approx, |

41 | |
42 | FirstPoint(myclass; ML: MLine) returns Integer; |
43 | ---Purpose: Returns the first index of multipoints of the MLine. |
44 | |
45 | |
46 | LastPoint(myclass; ML: MLine) returns Integer; |
47 | ---Purpose: Returns the last index of multipoints of the MLine. |
48 | |
49 | |
50 | |
51 | NbP2d(myclass; ML: MLine) returns Integer; |
52 | ---Purpose: Returns the number of 2d points of a MLine. |
53 | |
54 | |
55 | NbP3d(myclass; ML: MLine) returns Integer; |
56 | ---Purpose: Returns the number of 3d points of a MLine. |
57 | |
58 | |
59 | Value(myclass; ML: MLine; MPointIndex: Integer; tabPt: out Array1OfPnt); |
60 | ---Purpose: returns the 3d points of the multipoint <MPointIndex> |
61 | -- when only 3d points exist. |
62 | |
63 | |
64 | Value(myclass; ML: MLine; MPointIndex: Integer; |
65 | tabPt2d: out Array1OfPnt2d); |
66 | ---Purpose: returns the 2d points of the multipoint <MPointIndex> |
67 | -- when only 2d points exist. |
68 | |
69 | |
70 | Value(myclass; ML: MLine; MPointIndex: Integer; |
71 | tabPt: out Array1OfPnt; tabPt2d: out Array1OfPnt2d); |
72 | ---Purpose: returns the 3d and 2d points of the multipoint |
73 | -- <MPointIndex>. |
74 | |
75 | |
76 | Tangency(myclass; ML: MLine; MPointIndex: Integer; tabV: out Array1OfVec) |
77 | returns Boolean; |
78 | ---Purpose: returns the 3d derivative values of the multipoint |
79 | -- <MPointIndex> when only 3d points exist. |
80 | |
81 | |
82 | Tangency(myclass; ML: MLine; MPointIndex: Integer; |
83 | tabV2d: out Array1OfVec2d) |
84 | returns Boolean; |
85 | ---Purpose: returns the 2d derivative values of the multipoint |
86 | -- <MPointIndex> only when 2d points exist. |
87 | |
88 | |
89 | Tangency(myclass; ML: MLine; MPointIndex: Integer; |
90 | tabV: out Array1OfVec; tabV2d: out Array1OfVec2d) |
91 | returns Boolean; |
92 | ---Purpose: returns the 3d and 2d derivative values of the multipoint |
93 | -- <MPointIndex>. |
94 | |
95 | |
96 | |
97 | WhatStatus(myclass; ML: MLine; I1, I2: Integer) |
98 | returns Status from Approx; |
99 | ---Purpose: . if Status = PointsAdded, a new MLine is created between |
100 | -- the two MPoints <I1> and <I2> of ML by MakeMLBetween. |
101 | -- . if Status = NoPointsAdded, no MLine will be created. |
102 | -- The algorithm will return the best approximation done. |
103 | -- . if Status = NoApproximation, nothing will be |
104 | -- done between <I1> and <I2>. |
105 | |
106 | MakeMLBetween(myclass; ML: MLine; I1, I2: Integer; |
107 | NbPMin: Integer) |
108 | returns MLine; |
109 | ---Purpose: Is called if WhatStatus returned "PointsAdded". |
