ANALYSIS OF COMBINED POLYSURFACES TO MESH SURFACES MATCHING [PDF]
Scientific Journal of Silesian University of Technology. Series Transport, 2014 This article applies to an example of the process of quantitatively evaluate the fit of combined polysurface (NURBS class) to a surface mesh. The fitting process of the polysurface and the evaluation of obtained results have been realized in the ...

Inverse Relations for Blossoms and Parametrisations of Rational Curves and Surfaces
MathematicsIn this paper, we make use of an inverse formula that relates the blossom of a NURBS curve, surface or Bézier triangle with its parametrisation, with no explicit reference to the control points and weights of the parametrisation.
