DELFTship forum Hull modeling Subdivision surfaces Re: Subdivision surfaces


See the PDF document below for a mathematical description of a subdivision surface similar to the one used by Delftship.
As far as conversion from/to NURBS is concerned:

  • Uniform non-rational Bspline surfaces can be presented by subdivision surfaces exactly
  • Non-uniform or rational surfaces are approximated
  • Conversion to NURBS is also exact
