Improving Sampling-based Motion Control
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We address several limitations of the sampling-based motion control method of Liu et at. [LYvdP 10]. The key insight is to learn from the past control reconstruction trials through sample distribution adaptation. Coupled ... -
Scalable Partitioning for Parallel Position Based Dynamics
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We introduce a practical partitioning technique designed for parallelizing Position Based Dynamics, and exploiting the ubiquitous multi-core processors present in current commodity GPUs. The input is a set of particles ... -
Real-Time Subspace Integration for Example-Based Elastic Material
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Example-based material allows simulating complex material behaviors in an art-directed way. This paper presents a method for fast subspace integration for example-based elastic material, which is suitable for real-time ... -
Paint and Click: Unified Interactions for Image Boundaries
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Image boundaries are a fundamental component of many interactive digital photography techniques, enabling applications such as segmentation, panoramas, and seamless image composition. Interactions for image boundaries often ... -
Color Sequence Preserving Decolorization
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Many visualization techniques use images containing meaningful color sequences. If such images are converted to grayscale, the sequence is often distorted, compromising the information in the image.We preserve the significance ... -
Woodification: User-Controlled Cambial Growth Modeling
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We present a botanical simulation of secondary (cambial) tree growth coupled to a physical cracking simulation of its bark. Whereas level set growth would use a fixed resolution voxel grid, our system extends the deformable ... -
Self Tuning Texture Optimization
(The Eurographics Association and John Wiley & Sons Ltd., 2015)The goal of example-based texture synthesis methods is to generate arbitrarily large textures from limited exemplars in order to fit the exact dimensions and resolution required for a specific modeling task. The challenge ... -
Content-Independent Multi-Spectral Display Using Superimposed Projections
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Many works focus on multi-spectral capture and analysis, but multi-spectral display still remains a challenge. Most prior works on multi-primary displays use ad-hoc narrow band primaries that assure a larger color gamut, ... -
Light Chisel: 6DOF Pen Tracking
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We present a novel interaction device tracked in 6 degrees of freedom by two commodity cameras. The inexpensive Light Chisel is statically illuminated with two LEDs, and uses no additional sensor (e.g. inertial or magnetic) ... -
Hardware-Based Non-Photorealistic Rendering Using a Painting Robot
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We describe a painting machine and associated algorithms. Our modified industrial robot works with visual feedback and applies acrylic paint from a repository to a canvas until the created painting resembles a given input ... -
Approximating the Generalized Voronoi Diagram of Closely Spaced Objects
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We present an algorithm to compute an approximation of the generalized Voronoi diagram (GVD) on arbitrary collections of 2D or 3D geometric objects. In particular, we focus on datasets with closely spaced objects; GVD ... -
Interactive Disassembly Planning for Complex Objects
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We present an approach for the automatic generation, interactive exploration and real-time modification of disassembly procedures for complex, multipartite CAD data sets. In order to lift the performance barriers prohibiting ... -
Skeleton-Intrinsic Symmetrization of Shapes
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Enhancing the self-symmetry of a shape is of fundamental aesthetic virtue. In this paper, we are interested in recovering the aesthetics of intrinsic reflection symmetries, where an asymmetric shape is symmetrized while ... -
Shape-from-Operator: Recovering Shapes from Intrinsic Operators
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We formulate the problem of shape-from-operator (SfO), recovering an embedding of a mesh from intrinsic operators defined through the discrete metric (edge lengths). Particularly interesting instances of our SfO problem ... -
High Reliefs from 3D Scenes
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We present a method for synthesizing high reliefs, a sculpting technique that attaches 3D objects onto a 2D surface within a limited depth range. The main challenges are the preservation of distinct scene parts by preserving ... -
Approximating Free-form Geometry with Height Fields for Manufacturing
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We consider the problem of manufacturing free-form geometry with classical manufacturing techniques, such as mold casting or 3-axis milling. We determine a set of constraints that are necessary for manufacturability and ... -
3D Fabrication of 2D Mechanisms
(The Eurographics Association and John Wiley & Sons Ltd., 2015)The success of physics sandbox applications and physics-based puzzle games is a strong indication that casual users and hobbyists enjoy designing mechanisms, for educational or entertainment purposes. In these applications, ... -
Template Assembly for Detailed Urban Reconstruction
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We propose a new framework to reconstruct building details by automatically assembling 3D templates on coarse textured building models. In a preprocessing step, we generate an initial coarse model to approximate a point ... -
Layer-Based Procedural Design of Façades
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We present a novel procedural framework for interactively modeling building façades. Common procedural approaches, such as shape grammars, assume that building façades are organized in a tree structure, while in practice ... -
VDub: Modifying Face Video of Actors for Plausible Visual Alignment to a Dubbed Audio Track
(The Eurographics Association and John Wiley & Sons Ltd., 2015)In many countries, foreign movies and TV productions are dubbed, i.e., the original voice of an actor is replaced with a translation that is spoken by a dubbing actor in the country's own language. Dubbing is a complex ...
