Animated beer | Realistic fluid special effects in 3D


+ Last time, it was Quicker method for rendering "Realistic looking CG Hair" showcased in
2006 SIGGRAPH, which is developed by Steve Marschner assistant professor of computer science and his Cornell graduate student Jonathan Moon. This year, its "Animated beer"..Researchers from CSIRO and Korea’s ETRI poured a virtual glass of beer in San Diego at SIGGRAPH 07, the world’s largest computer graphics conference, which showcased their innovative fluid special effects software. The animation and rendering of fluids is a challenging problem in computer graphics. To achieve photorealism in the animation of fluids, a branch of maths called computational fluid dynamics is increasingly being used. CSIRO mathematicians are world leaders in this research.
CSIRO fluids researcher Dr. Mahesh Prakash says the physics of bubble creation in carbonated drinks like beer is complex. “As you pour beer into a glass, you see bubbles appearing on what are called nucleation sites, where the glass isn’t quite smooth,” - Dr. Prakash says.
“The bubbles expand to a certain size then rise up in streams to the surface, where they bump into each other and form a raft of foam that floats on the top.” says Dr Prakash and his colleagues have captured the maths describing these processes in software that allows movie makers, film production houses and others to create super-realistic special effects. The four-year project is being undertaken jointly by CSIRO and South Korea’s Electronics and Telecommunications Research Institute, one of the world’s largest computer graphics developers for games, with most of the research being done in Melbourne. The project is developing a software plug-in for Maya, the package of choice for high-end 3D Computer Graphics and 3D Modelling software within the film and animation industries.
