General Information

Since the very beginning of the Institute, a major part of our research topics dealt with rendering and modeling. Here you can get an overview of all the projects that fall within that category. We are also working on real-time rendering and procedural modeling, especially in the context of urban visualization.

Research areas


In this area, we concentrate on algorithms that synthesize images to depict 3D models or scenes, often by simulating or approximating the physics of light.

Geometry Processing

Uses concepts from applied mathematics and computer science to design efficient algorithms for the reconstruction, analysis, manipulation, simulation and transmission of complex 3D models. Example applications are collision detection, reconstruction, compression, occlusion-aware surface handling and improved sampling conditions.


The advent of consumer-grade 3D printing has recently sparked interest in fabrication-aware shape design and optimization. We use techniques from computer graphics and engineering to develop new computational tools to facilitate the design process of physical artifacts.


In this area, we focus on researching methods and algorithms that facilitate creation, representation, analysis and processing of 3D models.


In computer graphics we produce images, videos and other content that is perceived by humans. Unfortunately, human perception is still not well understood, making it hard to design algorithms that perfectly fit a user’s needs. Understanding how people see, do and perceive things is therefore a key component when optimizing and creating new rendering algorithms.
