Both the 4-point and the uniform cubic B-spline subdivisions double the number of vertices of a closed-loop polygon k P and produce sequences of vertices fj and bj respectively. W...
Direct volume rendering is an efficient method for plotting three dimensional scientific data. However, the technique is not as frequently used as it could be. In this article, we...

Most of these problems were presented at the conference on Combinatorics, Geometry and Computer Science, held at CIRM, Luminy, 2-4 May 2007. I have added one problem on a similar ...
This paper introduces a method to extract `Shape-DNA', a numerical fingerprint or signature, of any 2d or 3d manifold (surface or solid) by taking the eigenvalues (i.e. the s...

We present an efficient geometric algorithm for conic spline curve fitting and fairing through conic arc scaling. Given a set of planar points, we first construct a tangent contin...
