Interval methods for multi-point collisions between time-dependent curved surfaces
We present an efficient and robust algorithm for finding points of collision between time-dependent parametric and implicit surfaces. The algorithm detects simultaneous collisio...

Multiresolution analysis of arbitrary meshes
In computer graphics and geometric modeling, shapes are often represented by triangular meshes. With the advent of laser scanning systems, meshes of extreme complexity are rapidly...

Liquid simulation on lattice-based tetrahedral meshes
We describe a method for animating incompressible liquids with detailed free surfaces. For each time step, semiLagrangian contouring computes a new fluid boundary (represented as ...

Ricci Flow for 3D Shape Analysis
Ricci flow is a powerful curvature flow method in geometric analysis. This work is the first application of surface Ricci flow in computer vision. We show that previous methods ba...

Soft irregular shadow mapping: fast, high-quality, and robust soft shadows
We introduce a straightforward, robust, and efficient algorithm for rendering high-quality soft shadows in dynamic scenes. Each frame, points in the scene visible from the eye ar...
