REVERSE ENGINEERING
From Point Clouds to Timmed NURBS
(In Progress)

I'm currently working with Prof. Elaine Cohen on suface reconstruction from point clouds. The aim is to obtain a tensor product BSpline surface from scattered data. The issues involved include, preserving detail in the input, tackling noise (with with some kind of smoothing) , dealing with incomplete data and data with holes, finding a suitable parameterization for the data and so on.
