Information Media Environment Lab
Machine-translated · View original
A lab that uses computer graphics to create everything from clouds and flames to sound.
AboutAbout the lab
CG, just as you envision.
The Information Media Environment Lab works on a variety of topics in computer graphics (CG).
Its core interests are efficient rendering, fluid simulation, sound simulation, image-based methods, controllable graphics, haptics, and digital fabrication.
The lab researches and develops mechanisms that let users freely manipulate information in 3D space and easily create CG video.
With faculty members who specialize in human visual perception, the lab conducts research that uses CG to understand human information processing, as well as research on CG that exploits human visual perception.
Key terms
- Fluid simulation
- Reproducing the flow of water, smoke, flames, and the like by solving physical equations on a computer
- Digital fabrication
- Technology that makes physical objects from computer data, using tools such as 3D printers
- Psychophysics
- The study of the relationship between physical quantities such as light and sound and how people perceive them, investigated through experiments
ResearchResearch themes
The lab works on a variety of topics in computer graphics, aiming to take the field to a higher level. Its focus is efficient rendering, fluid and sound simulation, image-based methods, controllable graphics, haptics, and digital fabrication.
*Illustrative imageEfficient, Realistic Rendering
Producing precise images based on physical laws requires long computation times. The lab works on efficient, realistic computation and editing of radiance, and studies the rendering of atmospheric light scattering, light shafts, reflections on water surfaces, and more.
*Illustrative imageControlling Fluid Simulation
The lab simulates the flow of clouds, smoke, flames, and similar phenomena based on physical equations. By incorporating the latent heat released when clouds form as an adjustable parameter, it made it possible to create clouds with a desired shape and motion while preserving physical laws as much as possible.
*Illustrative imageGenerating Sound from Airflow
This is a technology that uses fluid dynamics to generate, in real time, the sound produced when a sword or stick is swung. It simulates the air pressure of the vortices that arise in the air and produces sound on the spot according to the thickness, material, and speed of the stick.
*Illustrative imageExploring How People See, and Applying It to CG
The lab investigates how people interpret the visual world, using methods from psychophysics and neuroscience. It works on research that uses CG to understand human information processing, and on CG research that exploits the characteristics of human visual perception.
