This node calculates so-called node points (also known as Greville points or
average knot points) of the NURBS curve.
NURBS curve nodes (or Greville abscissaes) are defined as:
t[i] = sum(u[i+j] for j from 1 to p) / p
, whereu
is curve's knotvector, andp
is curve's degree.NURBS curve node points (or Greville points) are points at the curve at
parameter values equal to node values.
The number of curve's nodes is equal to the number of curve's control points.
Node points of the curve are positioned on the curve near corresponding control
points. So in many NURBS algorithms, node points are used to define the shape
of NURBS curve, instead of control points.
