| 9 | |
| 10 | ---Purpose: This tool is used for transferring parameters |
| 11 | -- from 3d curve of the edge to pcurve and vice versa. |
| 12 | -- This tool transfers parameters with help of |
| 13 | -- projection points from curve 3d on curve 2d and |
| 14 | -- vice versa |
| 15 | uses |
| 16 | |
| 17 | Edge from TopoDS, |
| 18 | Face from TopoDS, |
| 19 | HSequenceOfReal from TColStd, |
| 20 | Location from TopLoc, |
| 21 | Curve from Geom, |
| 22 | Curve from Geom2d, |
| 23 | CurveOnSurface from Adaptor3d, |
| 24 | Vertex from TopoDS |
| 25 | is |
| 26 | |
| 27 | Create returns mutable TransferParametersProj from ShapeAnalysis; |
| 28 | ---Purpose: Creats empty constructor. |
| 29 | |
| 30 | Create(E: Edge from TopoDS; F: Face from TopoDS) |
| 31 | returns mutable TransferParametersProj from ShapeAnalysis; |
| 32 | ---Purpose: |
| 33 | |
| 34 | Init(me: mutable; E: Edge from TopoDS; F: Face from TopoDS ) is redefined; |
| 35 | ---Purpose: |
| 36 | |
| 37 | Perform(me: mutable; Papams: HSequenceOfReal from TColStd; To2d: Boolean) |
| 38 | returns HSequenceOfReal from TColStd is redefined; |
| 39 | ---Purpose: Transfers parameters given by sequence Params from 3d curve |
| 40 | -- to pcurve (if To2d is True) or back (if To2d is False) |
| 41 | |
| 42 | Perform(me: mutable; Param: Real; To2d: Boolean) |
| 43 | returns Real is redefined; |
| 44 | ---Purpose:Transfers parameter given by Param from 3d curve |
| 45 | -- to pcurve (if To2d is True) or back (if To2d is False) |
| 46 | |
| 47 | ForceProjection (me: mutable) returns Boolean; |
| 48 | ---Purpose: Returns modifiable flag forcing projection |
| 49 | -- If it is False (default), projection is done only |
| 50 | -- if edge is not SameParameter or if tolerance of edge |
| 51 | -- is greater than MaxTolerance() |
| 52 | ---C++: return & |
| 53 | |
| 54 | TransferRange(me: mutable; newEdge: in out Edge from TopoDS; |
| 55 | prevPar: Real; |
| 56 | currPar: Real; |
| 57 | Is2d : Boolean) is redefined; |
| 58 | ---Purpose: Recomputes range of curves from NewEdge. |
| 59 | -- If Is2d equals True parameters are recomputed by curve2d else by curve3d. |
| 60 | |
| 61 | IsSameRange(me) returns Boolean is redefined; |
| 62 | ---Purpose: Returns False; |
| 63 | -- |
| 64 | |
| 65 | PreformSegment(me: mutable;Param :Real; To2d :Boolean; |
| 66 | First :Real; Last :Real) |
| 67 | returns Real is private; |
| 68 | |
| 69 | CopyNMVertex(myclass; theVert: Vertex from TopoDS; |
| 70 | toedge: Edge from TopoDS; |
| 71 | fromedge: Edge from TopoDS ) returns Vertex from TopoDS; |
| 72 | ---Purpose: Make a copy of non-manifold vertex theVert |
| 73 | -- (i.e. create new TVertex and replace PointRepresentations for this vertex |
| 74 | -- from fromedge to toedge. Other representations were copied) |
| 75 | |
| 76 | CopyNMVertex(myclass; theVert: Vertex from TopoDS; |
| 77 | toFace: Face from TopoDS; |
| 78 | fromFace: Face from TopoDS ) returns Vertex from TopoDS; |
| 79 | ---Purpose: Make a copy of non-manifold vertex theVert |
| 80 | -- (i.e. create new TVertex and replace PointRepresentations for this vertex |
| 81 | -- from fromFace to toFace. Other representations were copied) |
