An energy-driven approach to linkage unfolding
We present a new algorithm for unfolding planar polygonal linkages without self-intersection based on following the gradient flow of a “repulsive” energy function. This algor...

Reeb graphs: approximation and persistence
Given a continuous function f : X → IR on a topological space X, its level set f−1 (a) changes continuously as the real value a changes. Consequently, the connected components...

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 ...

Pervasive views: area exploration and guidance using extended image media
This work achieves full registration of scenes in a large area and creates visual indexes for visualization in a digital city. We explore effective mapping, indexing, and display ...

Another Way of Looking at Plane-Based Calibration: The Centre Circle Constraint
Abstract. The plane-based calibration consists in recovering the internal parameters of the camera from the views of a planar pattern with a known geometric structure. The existing...
