Christopher Batty

Assistant Professor

Research interestsChristopher Batty

Professor Batty's research interests lie in the areas of computer
graphics and scientific computing. In particular, his work focuses on
physics-based animation, which combines elements of mechanics, geometry, numerical methods, and computer animation to approximate and predict the motion of objects and materials, with applications to entertainment and visual effects. His past work has considered a wide range of fundamental fluid phenomena, from simulating the unique coiling and folding motions of viscous liquids like honey, to representing and evolving the detailed geometry of a liquid surface as it undergoes complex topological merging and splitting. The techniques developed by Professor Batty for solid-fluid interaction and highly viscous liquids have been widely adopted within the film and visual effects industries, and incorporated into fluid animation software such as Side Effects Software's Houdini and Autodesk's BiFrost.

Degrees and awards

BCSc (Manitoba), PhD (University of British Columbia)

Banting Postdoctoral Fellow (2011)

Industrial and sabbatical experience

Prior to pursuing an academic career Professor Batty was a Research & Development Software Engineer at former Winnipeg-based visual effects studio Frantic Films, where he developed artist-friendly software tools for the physics-based animation of fluids and solids. During his PhD he spent internships at both Intel's Applications Research Lab in California, and New Zealand's Weta Digital, the visual effects studio behind Avatar and The Lord of the Rings. He has also collaborated with Ottawa-based computer graphics software company Exocortex Technologies on the development of spatially adaptive fluid animation techniques.
