    • A Framework for Local Terrain Deformation Based on Diffusion Theory 

      Gilardi, Marco (University of Sussex, 2015-10)
      Terrains have a key role in making outdoor virtual scenes believable and immersive as they form the support for every other natural element in the scene. Although important, terrains are often given limited interactivity ...

    • Geometric Methods for Realistic Animation of Faces 

      Bermano, Amit Haim (ETH Zurich, 2015)
      Realistic facial synthesis is one of the most fundamental problems in computer graphics, and has been sought after for approximately four decades. It is desired in a wide variety of fields, such as character animation ...

    • Illustrative Visualization of Medical Data Sets 

      Lawonn, Kai (2015-01-29)
      The aim of an illustrative visualization method is to provide a simplified representation of a complex scene or object. Concave and convex regions are emphasized and the surface complexity is reduced by omitting unnecessary ...

    • Interactive Integrated Exploration and Management of Visualization Parameters 

      Mindek, Peter (TU Wien, 2015-07)
      Visualization algorithms are parameterized to offer universality in terms of handling various data types, showing different aspects of the visualized data, or producing results useful for domain experts from different ...

    • Interactive Physically Based Simulation — Efficient Higher-Order Elements, Multigrid Approaches and Massively Parallel Data Structures 

      Weber, Daniel (2015-12-07)
