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.

"Hole-Filling Algorithm for Triangular Meshes", Lavanya Sita Tekumalla, Elaine Cohen, Technical Report, School of Computing, University of Utah, Dec 2004, UUCS-04-019. (Abstract).

Part of the work has been presented as a talk titled "Reverse Engineering Point Clouds to Trimmed NURBS" , Lavanya Sita Tekumalla, Elaine Cohen, at the conference 'Mathematical Methods for Curves and Surfaces', July 2004.(Abstract)

Hoping to put more exciting stuff shortly!!
Alpha 1
(Advanced Experimental CAD Modelling System)

My current responsibilities as a part of the Alpha 1 project include adding surface fitting code to Alpha 1
