22 | private class PrjResolve from ProjLib |
23 | |
24 | ---Purpose: |
25 | |
26 | uses |
27 | Pnt2d from gp, |
28 | Surface from Adaptor3d, |
29 | Curve from Adaptor3d, |
30 | SurfacePtr from Adaptor3d, |
31 | CurvePtr from Adaptor3d |
32 | |
33 | raises |
34 | DomainError from Standard, |
35 | ConstructionError, |
36 | NotDone from StdFail |
37 | |
38 | is |
39 | Create (C: Curve from Adaptor3d; S: Surface from Adaptor3d; Fix: Integer) |
40 | returns PrjResolve |
41 | raises ConstructionError; |
42 | |
43 | |
44 | Perform(me: in out; t, U, V: Real; Tol, Inf, Sup: Pnt2d; FTol: Real from Standard = -1; StrictInside: Boolean from Standard = Standard_False) |
45 | ---Purpose: Calculates the ort from C(t) to S with a close point. |
46 | -- The close point is defined by the parameter values |
47 | -- U0 and V0. |
48 | -- The function F(u,v)=distance(S(u,v),C(t)) has an |
49 | -- extremum when gradient(F)=0. The algorithm searchs |
50 | -- a zero near the close point. |
51 | raises DomainError; |
52 | -- if U0,V0 are outside the definition ranges of the |
53 | -- surface. |
54 | |
55 | |
56 | IsDone (me) returns Boolean |
57 | ---Purpose: Returns True if the distance is found. |
58 | is static; |
59 | |
60 | Solution (me) returns Pnt2d from gp |
61 | ---Purpose: Returns the point of the extremum distance. |
62 | raises NotDone from StdFail |
63 | -- if IsDone(me)=False. |
