19 ---Purpose: These global functions compute the degree of
20 -- continuity of a curve built by concatenation of two
21 -- edges at their junction point.
23 uses Standard, gp, BRepAdaptor, GeomAbs, LProp
31 class CLProps from BRepLProp
32 instantiates CLProps from LProp(Curve from BRepAdaptor,
36 CurveTool from BRepLProp);
38 class SLProps from BRepLProp
39 instantiates SLProps from LProp(Surface from BRepAdaptor,
40 SurfaceTool from BRepLProp);
43 Continuity(C1,C2 : Curve from BRepAdaptor;
44 u1,u2 : Real from Standard;
45 tl,ta : Real from Standard)
46 ---Purpose: Computes the regularity at the junction between C1 and
47 -- C2. The point u1 on C1 and the point u2 on C2 must be
48 -- confused. tl and ta are the linear and angular
49 -- tolerance used two compare the derivative.
50 returns Shape from GeomAbs;
53 Continuity(C1,C2 : Curve from BRepAdaptor;
54 u1,u2 : Real from Standard)
55 ---Purpose: The same as preciding but using the standard
56 -- tolerances from package Precision.
57 returns Shape from GeomAbs;
