Conformal Flattening by Curvature Prescription and Metric Scaling
We present an efficient method to conformally parameterize 3D mesh data sets to the plane. The idea behind our method is to concentrate all the 3D curvature at a small number of s...

Real-Time Simulation of Thin Shells
This paper proposes a real-time simulation technique for thin shells undergoing large deformation. Shells are thin objects such as leaves and papers that can be abstracted as 2D s...

Comparison of the Hansen-Sengupta and the Frommer-Lang-Schnurr existence tests
The Krawczyk and the Hansen-Sengupta interval operators are closely related to the interval Newton operator. These interval operators can be used as existence tests to prove exist...

Another hybrid conjugate gradient algorithm for unconstrained optimization
Another hybrid conjugate gradient algorithm is subject to analysis. The parameter k is computed as a convex combination of HS k (Hestenes-Stiefel) and DY k (Dai-Yuan) algorithms, i...
