NAME

BspKnotAllC1Discont()

SYNOPSIS

cagd_lib/bsp_knot.c:1272

CagdRType *BspKnotAllC1Discont(CagdRType *KnotVector,
                               int Order,
                               int Length,
                               int *n)

DESCRIPTION

Scans the given knot vector for all potential C1 discontinuity. Returns a vector holding the parameter values of the potential C1 discontinuities, NULL of none found. Sets n to length of returned vector. Assumes knot vector has open end condition. A knot vector with multiplicity of a knot of (Order - 1) can be C1 discontinuous at that knot. However, this is only a necessary condition for C1 discontinuity in the geometry.

PARAMETERS:

KnotVector: To test for potential C1 dicontinuities.

Order: Of geometry that exploits KnotVector.

Length: Length of curve/surface using KnotVector. This is NOT the length of KnotVector which is equal to (Length + Order).

n: Length of returned vector - number of potential C1 discontinuities found.

FUNCTION RETURN VALUE

CagdRType *: Vector holding all parametr values with potential C1 discontinuities.
