package GeomLProp
---Purpose: These global functions compute the degree of
-- continuity of a 3D curve built by concatenation of two
-- other curves (or portions of curves) at their junction point.

r1,r2 : Boolean from Standard;
tl,ta : Real from Standard)
---Purpose: Computes the regularity at the junction between C1 and
-- C2. The booleans r1 and r2 are true if the curves must
-- be taken reversed. The point u1 on C1 and the point
-- u2 on C2 must be confused.
-- tl and ta are the linear and angular tolerance used two
-- compare the derivative.
returns Shape from GeomAbs;
Continuity(C1,C2 : Curve from Geom;
u1,u2 : Real from Standard;
r1,r2 : Boolean from Standard)
---Purpose: The same as preciding but using the standard
-- tolerances from package Precision.
returns Shape from GeomAbs;
