This is an example of how to use the Fit SOP to fit a NURBs curve to a basic polygon curve.
Fitting builds a new NURBs or Bezier curve through the input geometry’s points.
There are two methods for doing this:
Interpolation fitting outputs the same number of cv’s as the input curve (Original Polygon Curve).
Approximation fitting reduces the number of cv’s, while approximating a curve through the input points.
Play the animation to see how these two methods affect the resultant curve over time.
