Polygon smoothing nurbs curves and surfaces (2005)
Presentation / Conference Contribution
Li, Q. (2005, June). Polygon smoothing nurbs curves and surfaces. Presented at Applied Simulation and Modelling (ASM 2005), Benalmádena, Spain

In conventional spline geometric shape design, each part of a designed object always evolves the same number of con trol points. This has been a disadvantage of the spline based geometric shape design schemes as much more points than necessary may be... Read More about Polygon smoothing nurbs curves and surfaces.
