NAME
SymbCrvOffset()
SYNOPSIS
symb_lib/offset.c:51
CagdCrvStruct *SymbCrvOffset(CagdCrvStruct *Crv,
CagdRType OffsetDist,
CagdBType BezInterp)
DESCRIPTION
Given a curve and an offset amount OffsetDist, returns an approximation to
the offset curve by offseting the control polygon in the normal direction.
PARAMETERS:
Crv: To approximate its offset curve with distance OffsetDist.
OffsetDist: Amount of offset. Negative denotes other offset direction.
BezInterp: If TRUE, control points are interpolated when the curve is
reduced to a Bezier form. Otherwise, control points are
translated OffsetDist amount only, under estimating the
Offset.
FUNCTION RETURN VALUE
CagdCrvStruct *: An approximation to the offset curve.
