My name is Wang Xu. I am a Project Assistant Professor in the Intelligent Robots and Systems Laboratory at Hokkaido University, where I work under the supervision of Professors Atsushi Konno and Satoshi Kanai. I received my Ph.D. in Informatics from the University of Tsukuba, advised by Professors Makoto Fujisawa and Masahiko Mikawa. My research interests include physics-based simulation, XR technologies, image processing, style transfer, and related topics in computer graphics.

XProtoSphere: an eXtended Multi-Sized Sphere Packing Algorithm Driven by Particle Size Distribution
XProtoSphere: an eXtended Multi-Sized Sphere Packing Algorithm Driven by Particle Size Distribution

Xu Wang, Makoto Fujisawa, Masahiko Mikawa

The Visual Computer (Computer Graphics International) 2023

We propose a novel PSD-driven technique that extends the ProtoSphere algorithm to achieve multi-sized sphere packing with distribution-specific characteristics, as dictated by a pre-defined cumulative distribution function. Our method improves the controllability and flexibility of the packing process, enabling users to generate packing configurations that meet their specific requirements.

Visual Simulation of Soil-Structure Destruction with Seepage Flows

Xu Wang, Makoto Fujisawa, Masahiko Mikawa

Proceedings of the ACM on Computer Graphics and Interactive Techniques (ACM SIGGRAPH / Eurographics Symposium on Computer Animation) 2021

This paper introduces a method for simulating soil-structure coupling with water, involving visual effects such as wet granular materials, seepage flows, capillary action between grains, and dam breaking simulation.
