We introduce the <i>heat method</i> for computing the geodesic distance to a specified subset (e.g., point or curve) of a given domain. The heat method is robust, efficient, and simple to implementâ€¦ (More)

We capture the shape of moving cloth using a custom set of color markers printed on the surface of the cloth. The output is a sequence of triangle meshes with static connectivity and with detail atâ€¦ (More)

This paper presents a straightforward algorithm for constructing connections on discrete surfaces that are as smooth as possible everywhere but on a set of isolated singularities with given index. Weâ€¦ (More)

Using the GPU to accelerate ray tracing may seem like a natural decision due to the highly parallel nature of the problem. However, past attempts at a fully general GPU ray tracer have yielded poorâ€¦ (More)

We present a method for constructing smooth <i>n</i>-direction fields (line fields, cross fields, <i>etc</i>.) on surfaces that is an order of magnitude faster than state-of-the-art methods, whileâ€¦ (More)

Numerical viscosity has long been a problem in fluid animation. Existing methods suffer from intrinsic artificial dissipation and often apply complicated computational mechanisms to combat suchâ€¦ (More)

We present a formulation of Willmore flow for triangulated surfaces that permits extraordinarily large time steps and naturally preserves the quality of the input mesh. The main insight is thatâ€¦ (More)

Many mesh parameterization algorithms have focused on minimizing distortion and utilizing texture area, but few have addressed issues related to processing a signal on the mesh surface. We present anâ€¦ (More)
