Real Nurbs ? 2004-02-12 - By Jon Baird
Back
NURBS stands for a Non Uniform Rational B-Spline and
is a mathematical way to interpolate a between points
in a set. It is a parametric representation of curves
and surfaces. I think C4D uses the term HyperNURBS,
which is a trademark I believe, to describe their
implementation of subdivision surfaces. When people
say this or that application doesn't have real NURBS I
often think they mean it doesn't support NURBS
surfaces. For instance, in C4D HyperNURBS may not be a
true NURBS surface, but there are bezier curves, b-
spline curves and other types of curves, which are I
think so-called real NURBS. LW has bezier curves, too,
which mathematically speaking are a special case of
the more general set of curves defined by NURBS
equations.
