Surface-Only Methods for Simulating Flow and Fracutre

Date: Tuesday, 3rd of July, 2018, 2-3pm
Place: Seminar room 1, ground floor, ICT building


Physical simulation is a valuable tool for creating extremely detailed and realistic animations of natural phenomena. However, simulations of fluids and elastic bodies can become very computationally expensive, because they require the solution of complicated partial differential equations over an entire 3D volume.

To make matters worse, this expensive computation is often repeated over many time steps. In our recent research, we developed methods for solving these problems using only the surface, instead of the entire volume. This boundary-only strategy can lead to significantly less memory storage, orders of magnitude faster computation, and theoretically interesting perspectives on the original problem.

In this talk, I will present an overview of some recent projects that introduce surface-only methods for simulating bubbles, splashes, ripples, and fractures.


Chris Wojtan is a Professor at the Institute of Science and Technology Austria (IST Austria). He received his Ph.D. in Computer Graphics from the Georgia Institute of Technology in 2010. He has written over 30 research papers on physics simulation and geometry processing, the majority of which are published in ACM SIGGRAPH. Much of his research aims to find efficient numerical solutions for physics problems that couple complicated geometry and topology, with particular emphasis on generating liquid motion and fracture patterns. His work has been awarded the NSF Graduate Research Fellowship, the Georgia Tech Sigma Xi Best Doctoral Dissertation Award, the Microsoft Visual Computing Award, an ERC Starting Grant, the Eurographics Young Researcher Award, and the ACM SIGGRAPH Significant New Researcher Award.
