CESCG 2011 - Preliminary Program

The simulation of various natural phenomena is one of the important research fields in computer graphics. In particular, aspects such as clouds, water, smoke, and sands are indispensable for creating realistic images of natural scenes. Therefore, a lot of researchers have been trying to develop methods for simulating and rendering these scenes. In my presentation I focus on water, granular materials, clouds, atmospheric effects. These phenomena have the common feature that they are consist of the effects of small particles. And the color greatly depends on the properties of light scattering due to particles. To create realistic images, physical based simulation and rendering are required. In particular, the color greatly depends on the properties of light scattering due to particles. I would like to introduce efficient methods for creating realistic images of such natural phenomena. Recently, the results of particle-based simulati ons have been often visualized using a large number of metaballs. I introduce a fast technique for rendering metaballs on the GPU.

Accurate computational representations of highly deformable surfaces are indispensable in the fields of computer animation, medical simulation, computer vision, digital modeling, and computational physics. After reviewing common representations of deformable surfaces, I will present some of my recent contributions to the field of computer graphics.

I will first present results from an algorithm that generates highly detailed continuum mechanics animations by combining a finite element method with a tetrahedral mesh generator and a high resolution surface mesh. Next, I will present an efficient solution for the challenging problem of computing topological changes between detailed surface meshes, allowing us to track surfaces in computational fluid dynamics applications with unprecedented levels of accuracy and detail. This surface tracking technique also opens the door for a unique coupling between surficial finite element methods and volumetric finite difference methods, in order to simulate liquid surface tension phenomena more efficiently than any previous method. Due to its dramatic increase in computational resolution and efficiency, this method yielded the first computer simulations of a fully developed crown splash with droplet pinch off.
