GazeDirector: Fully Articulated Eye Gaze Redirection in Video
(The Eurographics Association and John Wiley & Sons Ltd., 2018)We present GazeDirector, a new approach for eye gaze redirection that uses model-fitting. Our method first tracks the eyes by fitting a multi-part eye region model to video frames using analysis-by-synthesis, thereby ... -
Hair Modeling and Simulation by Style
(The Eurographics Association and John Wiley & Sons Ltd., 2018)As the deformation behaviors of hair strands vary greatly depending on the hairstyle, the computational cost and accuracy of hair movement simulations can be significantly improved by applying simulation methods specific ... -
Improved Functional Mappings via Product Preservation
(The Eurographics Association and John Wiley & Sons Ltd., 2018)In this paper, we consider the problem of information transfer across shapes and propose an extension to the widely used functional map representation. Our main observation is that in addition to the vector space structure ... -
Interactive Generation of Time-evolving, Snow-Covered Landscapes with Avalanches
(The Eurographics Association and John Wiley & Sons Ltd., 2018)We introduce a novel method for interactive generation of visually consistent, snow-covered landscapes and provide control of their dynamic evolution over time. Our main contribution is the real-time phenomenological ... -
MIQP-based Layout Design for Building Interiors
(The Eurographics Association and John Wiley & Sons Ltd., 2018)We propose a hierarchical framework for the generation of building interiors. Our solution is based on a mixed integer quadratic programming (MIQP) formulation. We parametrize a layout by polygons that are further decomposed ... -
Motion Sickness Simulation Based on Sensorimotor Control
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Sensorimotor control is an essential mechanism for human motions, from involuntary reflex actions to intentional motor skill learning, such as walking, jumping, and swimming. Humans perform various motions according to ... -
Multiple Scattering in Inhomogeneous Participating Media Using Rao-Blackwellization and Control Variates
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Rendering inhomogeneous participating media requires a lot of volume samples since the extinction coefficient needs to be integrated along light paths. Ray marching makes small steps, which is time consuming and leads to ... -
A New Microflake Model With Microscopic Self-shadowing for Accurate Volume Downsampling
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Naive linear methods for downsampling high-resolution microflake volumes often produce inaccurate appearance, especially when input voxels are very opaque. Preserving correct appearance at all resolutions requires taking ... -
Packable Springs
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Laser cutting is an appealing fabrication process due to the low cost of materials and extremely fast fabrication. However, the design space afforded by laser cutting is limited, since only flat panels can be cut. Previous ... -
Parallel Reinsertion for Bounding Volume Hierarchy Optimization
(The Eurographics Association and John Wiley & Sons Ltd., 2018)We present a novel highly parallel method for optimizing bounding volume hierarchies (BVH) targeting contemporary GPU architectures. The core of our method is based on the insertion-based BVH optimization that is known to ... -
PCPNet: Learning Local Shape Properties from Raw Point Clouds
(The Eurographics Association and John Wiley & Sons Ltd., 2018)In this paper, we propose PCPNET, a deep-learning based approach for estimating local 3D shape properties in point clouds. In contrast to the majority of prior techniques that concentrate on global or mid-level attributes, ... -
A Physically Consistent Implicit Viscosity Solver for SPH Fluids
(The Eurographics Association and John Wiley & Sons Ltd., 2018)In this paper, we present a novel physically consistent implicit solver for the simulation of highly viscous fluids using the Smoothed Particle Hydrodynamics (SPH) formalism. Our method is the result of a theoretical and ... -
PointProNets: Consolidation of Point Clouds with Convolutional Neural Networks
(The Eurographics Association and John Wiley & Sons Ltd., 2018)With the widespread use of 3D acquisition devices, there is an increasing need of consolidating captured noisy and sparse point cloud data for accurate representation of the underlying structures. There are numerous ... -
Practical Radiometric Compensation for Projection Display on Textured Surfaces using a Multidimensional Model
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Radiometric compensation methods remove the effect of the underlying spatially varying surface reflectance of the texture when projecting on textured surfaces. All prior work sample the surface reflectance dependent ... -
Procedural Cloudscapes
(The Eurographics Association and John Wiley & Sons Ltd., 2018)We present a phenomenological approach for modeling and animating cloudscapes. We propose a compact procedural model for representing the different types of cloud over a range of altitudes. We define primitive-based field ... -
Procedural Modeling of a Building from a Single Image
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Creating a virtual city is demanded for computer games, movies, and urban planning, but it takes a lot of time to create numerous 3D building models. Procedural modeling has become popular in recent years to overcome this ... -
Real-time Locomotion Controller using an Inverted-Pendulum-based Abstract Model
(The Eurographics Association and John Wiley & Sons Ltd., 2018)In this paper, we propose a novel motion controller for the online generation of natural character locomotion that adapts to new situations such as changing user control or applying external forces. This controller ... -
Real-Time Rendering of Wave-Optical Effects on Scratched Surfaces
(The Eurographics Association and John Wiley & Sons Ltd., 2018)The visual appearance of real-world materials is characterized by surface features across many scales and has received significant attention by the graphics community for decades. Yet, even the most advanced microfacet ... -
Repairing Inconsistent Curve Networks on Non-parallel Cross-sections
