SIAM IMR25: Short Courses

Courses are taught by internationally known experts. Instructors typically include an overview of the state of the art of their topic, and highlight their own research, but also include the current work of others. It is intended to be a “course” in the traditional sense of enabling attendees to go forth and produce new results of their own, rather than simply use existing knowledge.

Robust Low-Poly Meshing for Mobile Games

Dr. Xifeng Gao

Abstract: Low-poly meshes are essential in the development of mobile games due to their efficiency in real-time rendering, animation, and data storage. However, creating high-quality low-poly models often requires manual effort to strike the ideal balance between a minimal polygon count and the preservation of visual and shape fidelity, among other considerations. This process can be time-consuming, even for skilled artists, and typically involves a tedious cycle of trial and error.

In this talk, I will introduce several techniques that leverage domain knowledge in geometry processing, computer graphics, and machine learning to automatically generate low-poly meshes optimized for mobile game applications.

Biography: Xifeng Gao is a principal researcher at LightSpeed Studios. He has more than 10 years of academic research experience, with a focus on geometry computing. The target applications are computer graphics, computer-aided-design and analysis, and robotics. He has more than 60 peer-reviewed papers published in top-ranked journals and conferences.

On the topic of mesh refinements via subdivision schemes and progressive iterative approximation methods

Prof. Lucia Romani

Abstract: Coming soon.

Biography: Lucia Romani received a PhD in Computational Mathematics (research area of Numerical Analysis) from the University of Padua (Italy) in 2004. After working for seven years as an assistant professor at the Department of Mathematics of the University of Milan-Bicocca (Italy), in 2014 she was promoted to associate professor. In 2018 she moved to the Department of Mathematics, University of Bologna (Italy) where she was promoted to full professor in 2022.

Her research interests span the fields of approximation theory, geometric modelling and CAGD, with a special focus on splines, subdivision schemes and their applications.

Lucia is author and co-author of 80+ peer-reviewed scientific publications, 70+ in international journals.
