Real-Time Rendering and Representations (Former Research Group)

The research group "Real-Time Rendering and Representations", headed by Elmar Eisemann, was part of the Cluster of Excellence MMCI from October 2008 to December 2009.

Vision and Research Strategy

Today, computer graphics has become an important element in many contexts. Simulation, data representation and analysis, scientific illustrations, games, movies and many more fields benefit from recent advances. Still, computer-produced content differs from images captured directly from the real world. Only with manual involvement is it currently possible to achieve convincing images. Unfortunately, manual tweaks often lead to a solution that addresses only a particular system, which is problematic given the wide range of devices we encounter today (projectors, screens with various resolutions, 2D/3D content, portable devices...). Consequently, we investigate how to produce convincing graphics and achieve scalability over various devices. Nonetheless, artistic intervention can be useful to produce different expressive effects, such as the mood in a movie, or the clarity of a manual.

Our solution is to develop algorithms that produce high-quality imagery, but provide a fine tradeoff between fidelity and performance. We particularly focus on real-time interaction, because it is not only crucial for simulations and games, but also serves in the context of content creation. Artists need instant feedback to evaluate appearance.

Specifically, we investigate several directions: First, the creation of detailed images and the depiction of highly complex environments, which implies the need for efficient algorithms to simulate physical phenomena. Second, scalable solutions, to address the hardware that is involved in the image creation process. This means that an algorithm should have potential to be executed on a portable device, as well as on a high-end machine. Third, perceptual issues, because the final image is displayed to and perceived by a user. In particular, this gives rise to research in the direction of expressive rendering where an image does not necessarily exhibit realistic characteristics. Instead an image should be attractive and easy to understand, as in stylized illustrations for assembly instructions.

Composition of Group

The research group Real-time Rendering and Representations headed by Elmar Eisemann was established in October 2008. In April 2009, Lionel Baboud joined the group as a postdoctoral researcher, supported by the Cluster of Excellence.

The research group investigates the production of realistic and expressive images. Its focus is on the development of algorithms and data structures for the efficient creation and rendering of visual content with high quality.

In February 2010, Elmar Eisemann became an associate professor at Telecom ParisTech, but maintains close ties to the cluster.
