New Applications of Particle Systems to Shape Modeling

When: Wednesday, November 6, 2013
Where: PGH 563 Please note room #
Time: 4:00 PM Please note time

Speaker: Prof. Wenping Wang, Hong Kong University

Host: Dr. Zhigang Deng

Particle systems are widely used in computer graphics, especially in computation animation and fluid simulation. In this talk, I shall first revisit two different energy functions of a particle system: the one based on centroidal Voronoi tessellation and the one based on Gaussian kernels, and introduce some key properties and efficient computational schemes. Then I shall present our recent research on applying particle systems to solving a variety of problems in shape modeling and processing, including mesh generation, blue-noise point sampling, geometric packing, and minimal surface modeling.
