报告题目：A Tutorial on How to Simulate Versatile Physical Materials with Particle-based Methods
报告摘要：

Particle-based methods have become an important modeling tool for computer graphics. Compared to other methods, particle-based methods are easy to implement, but powerful enough to create a variety of dynamic scenarios, thus has been widely used in both films and video games. In this talk, I will describe the main techniques and fundamental theories necessary to learn and simulate physical materials with particle-based methods. I will show how to simulate versatile materials ranging from incompressible fluids to elastoplastic solids and granular matters. I will conclude my presentation by outlining the challenges in developing high-fidelity particle-based methods.

报告题目：GPU Optimizations of Material Point Method and Collision Detection

报告摘要：

The material point method has been a research focus in computer graphics for some time. It has the advantages of handling complex topology changes, multi-material and multiphase coupling, (self) collisions, etc., in an elegant way. However, its generalization is usually hindered by time step restrictions and heavy computation workloads. In this talk, we start by designing an efficient pipeline of the material point method for the GPU. Several major technical challenges will be discussed, and an optimized parallel implementation will be presented. Additionally, more GPU optimization patterns and strategies will be briefly discussed surrounding the broad-phase collision detection.
