    Accurate Face Reconstruction through Anisotropic Fitting and Eye Correction
    (The Eurographics Association, 2015) Achenbach, Jascha; Zell, Eduard; Botsch, Mario; David Bommes and Tobias Ritschel and Thomas Schultz
    Fitting a facial template model to 3D-scanner data is a powerful technique for generating face avatars, in particular in the presence of noisy and incomplete measurements. Consequently, there are many approaches for the underlying non-rigid registration task, and these are typically composed from very similar algorithmic building blocks. By providing a thorough analysis of the different design choices, we derive a face matching technique tailored to high quality reconstructions from high resolution scanner data. We then extend this approach in two ways: An anisotropic bending model allows us to more accurately reconstruct facial details. A simultaneous constrained fitting of eyes and eye lids improves the reconstruction of the eye region considerably.

    Simulation of Water Condensation based on a Thermodynamic Approach
    (The Eurographics Association, 2015) Tillmann, Sebastian-T.; Bohn, Christian-A.; David Bommes and Tobias Ritschel and Thomas Schultz
    We introduce a novel approach for physically based simulation of water drops on surfaces considering the thermodynamical laws like mixing temperature, specific heat capacity, water vapor, saturation, and additional material properties in an adiabatic environment. The algorithm is able to robustly handle huge scenes of complex closed and also non-closed objects defined as implicit surfaces and thus it is ideally suited for extending classical, wellknown fluid simulation models. A subset of thermodynamic rules based on a static grid is used. Other approaches use buoyant force and other equations based on motion, e. g. [HBSL03].
