After completing a postdoc at Aarhus University in 2010-11, I was a research contractor in the research group at Weta Digital – the main visual effects vendor behind movies such as the Lord of the Rings trilogy and Avatar. I will describe some of the research challenges we were faced with during production on the movie Adventures of Tintin – Secret of the Unicorn. Solutions to the challenges were later published at some of the leading conferences and journals in computer graphics and include cutting edge results in rendering and simulation. In this talk I will provide an overview but focus on the results achieved in fluid simulation. I will also share some of my personal experience from working in the VFX industry and learning from the VFX wizards of middle earth. I have now returned to an assistant professor position at Aarhus University, and please note that since I am not a representative of Weta Digital, this talk will only cover material already in the public domain.


Following the recent open sourcing of DreamWorks Animation’s sparse volume toolkit, OpenVDB and SideFX’s subsequent announcement to integrate it in its next major release of Houdini, this presentation is targeting early adopters that wish to experiment with the new technology. Fans of OpenVDB use the phrase “batteries included” to describe the fact that the library ships with a rich toolset of high-level volumetric processing and conversion tools that can be applied directly in VFX pipelines. The presentation will focus on three aspects of Ken Museth’s OpenVDB: 1) a description of its underlying data structures and its accompanying toolset, 2) its integration into Houdini as a first-class citizen, and 3) a tour of the existing Houdini nodes that are included in the open
source distribution.
