24 | deferred generic class ParTool from IntImpParGen |
25 | (ParCurve as any) |
26 | |
27 | ---Purpose: Template class for a tool on a parametrised curve. |
28 | |
29 | uses Pnt2d from gp, |
30 | Vec2d from gp, |
31 | Lin2d from gp |
32 | |
33 | is |
34 | |
35 | |
36 | Value (myclass; C: ParCurve; U: Real from Standard) |
37 | |
38 | ---Purpose: Returns the point at parameter U on the Curve C. |
39 | |
40 | returns Pnt2d from gp; |
41 | |
42 | |
43 | D1 (myclass; C:ParCurve; U:Real from Standard ; |
44 | P: out Pnt2d; T: out Vec2d); |
45 | |
46 | ---Purpose: Computes the Point and the First derivative of |
47 | -- the parametric curve C at parameter U. |
48 | |
49 | |
50 | D2 (myclass; C:ParCurve; U:Real from Standard ; |
51 | P: out Pnt2d; T,N: out Vec2d); |
52 | |
53 | ---Purpose: Computes the Point, the First and the Second derivative of |
54 | -- the parametric curve C at parameter U. |
55 | |
56 | |
57 | EpsX (myclass; C: ParCurve) |
58 | |
59 | ---Purpose: Returns the valuec of the parametric tolerance |
60 | -- on the curve C. |
61 | |
62 | returns Real from Standard; |
63 | |
64 | |
65 | NbSamples(myclass; C: ParCurve) |
66 | |
67 | ---Purpose: NbSamples is the number of sample point used to |
68 | -- polygonise the parametric curve on its domain. |
69 | |
70 | returns Integer from Standard; |
