NAME

BspKnotAffineTrans()

SYNOPSIS

cagd_lib/bsp_knot.c:448

void BspKnotAffineTrans(CagdRType *KnotVector,
                        int Len,
                        CagdRType Translate,
                        CagdRType Scale)

DESCRIPTION

Applies an affine transformation to the given knot vector. Note affine transformation on the knot vector does not change the Bspline curve. Knot vector is translated by Translate amount and scaled by Scale as
KV[i] = (KV[i] - KV[0]) * Scale + (KV0 + Translate). All transformation as taken place in place.

PARAMETERS:

KnotVector: To affinely transform.

Len: Of knot vector. This is not the length of the curve or surface using this knot vector.

Translate: Amount to translate the knot vector.

Scale: Amount to scale the knot vector.

FUNCTION RETURN VALUE

void
