Industry Partners

- Weta Digital: research collaboration and technology transfer on multiple topics in the area of physically-based photorealistic rendering for visual effects in movies. Our contributions have been used in Hollywood blockbusters such as The Hobbit and Dawn of The Planet of the Apes

- Render Legion (Corona Renderer) and Chaos Group (V-ray): collaborative research and technology transfer aimed at the development of the physically-based Corona and V-ray renderers, with focus on architectural and product visualisation

- Disney Research Zurich (DRZ): collaborative research on Monte Carlo methods for realistic rendering of optically participating media such as smoke, clouds, joice, skin etc.

- PIXAR Animation Studios: technology transfer of the research results developed together with DRZ into the industry-standard rendering software developed by Pixar, Photorealistic RenderMan

Key Research Equipment

We possess efficient software implementations of some of the most advanced light transport simulation algorithms that are known today.

Our graphics software is also capable of simulating of physical effects that are still uncommon in mainstream software, such as light polarisation and fluorescence.

We have developed a 3D printing driver for PolyJetting printers, capable of accurate color and texture reproduction.

Furthermore, we maintain the Morphome3cs codebase, a unified software for biomedical research that features tools for surface data acquisition, statistical shape analysis and result presentation.
