DESCRIPTION:Subdivision is a powerful modelling technique used in many\nap
 plications including computer games and animated films. Subdivision\nschem
 es are predominantly based on cubic B-splines and produce smooth\nsurfaces
  everywhere. However\, it is known that using an everywhere\nsmooth surfac
 e to model sharp features (such as those on mechanical\nparts) results in 
 poor geometric fits and unwanted undulations.\n\nI will explore and compar
 e existing techniques for modelling\n(semi-)sharp features on subdivision 
 curves and surfaces and outline a\nnovel approach that generalises to arbi
 trary degree subdivision and\nany level of (dis)continuity.
