The lab uses particle methods to reproduce everything from water splashes to body movements on a computer.
AboutAbout the lab
Reproducing complex phenomena through the motion of particles
The Koshizuka-Shibata Lab studies methods for reproducing a variety of complex phenomena on computers.
Using the MPS method, the lab's own particle method, it can calculate even complex phenomena such as water splashes.
The MPS method has been turned into commercial software by private companies and is used in a variety of industries.
The lab also works on applications to disasters, ships, and medicine, and on creating CG images based on simulation.
Key terms
- Particle method
- A simulation method that represents water and other materials as a collection of small particles and calculates the motion of each one.
- MPS method
- A particle method developed independently by this lab. It can handle large deformations of the water surface and splashes.
- Physically based CG
- CG that creates realistic images from the results of simulations based on the laws of physics.
ResearchResearch themes
The lab studies methods for reproducing a variety of complex phenomena on computers, using particle methods and other approaches. It also works on applications to disasters, ships, manufacturing, and biological and medical fields, as well as on physically based CG.
*Illustrative imageParticle-based simulation methods
Centered on the MPS method, the lab's own particle method, the lab studies how to improve the accuracy and stability of calculations, speeding them up with GPUs, and computational models for surface tension and turbulence.
*Illustrative imageApplications of simulation
Topics include tsunami analysis using real terrain, interaction between ships and waves, and flows in resin production and composite material molding. Many of these are joint research projects with other organizations.
*Illustrative imagePhysically based CG
This research efficiently creates realistic images based on simulation results. It covers rendering techniques, GPU acceleration, and interactive CG using VR devices.
*Illustrative imageBiological and medical applications
Using a particle method that handles the large deformations of soft tissue easily, the lab simulates lung motion during breathing and the act of swallowing, in collaboration with medical schools and hospitals.
