We present a new algorithm to compute stable discrete minimal surfaces bounded by a number of Ãžxed or free boundary curves in R, S and H. The algorithm makes no restriction on the genus and canâ€¦ (More)

We advocate a simple geometric model for elasticity: <i>distance between the differential of a deformation and the rotation group</i>. It comes with rigorous differential geometric underpinnings,â€¦ (More)

We present a new algorithm for conformal mesh parameterization. It is based on a precise notion of <i>discrete conformal equivalence</i> for triangle meshes which mimics the notion of conformalâ€¦ (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)

In the middle of the 19th century two important theories emerged: the first, developed by Gauss, dealt with the fundamental equations of surfaces in 3-space. The second, developed by Riemann, wasâ€¦ (More)

We show how pairs of isothermic surfaces are given by curved flats in a pseudo Riemannian symmetric space and vice versa. Calapsoâ€™s fourth order partial differential equation is derived and, using aâ€¦ (More)

Modelling incompressible ideal fluids as a finite collection of vortex filaments is important in physics (super-fluidity, models for the onset of turbulence) as well as for numerical algorithms usedâ€¦ (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)

Over the last decades it has been widely recognized that many completely integrable PDEâ€™s from mathematical physics arise naturally in geometry. Their integrable character in the geometric context â€“â€¦ (More)
