Watercolor Woodblock Printing with Image Analysis
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Watercolor paintings have a unique look that mixes subtle color gradients and sophisticated diffusion patterns. This makes them immediately recognizable and gives them a unique appeal. Creating such paintings requires ... -
Efficient BVH-based Collision Detection Scheme with Ordering and Restructuring
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Bounding volume hierarchy (BVH) has been widely adopted as the acceleration structure in broad-phase collision detection. Previous state-of-the-art BVH-based collision detection approaches exploited the spatio-temporal ... -
Fast Penetration Volume for Rigid Bodies
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Handling collisions among a large number of bodies can be a performance bottleneck in video games and many other real-time applications. We present a new framework for detecting and resolving collisions using the penetration ... -
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 ... -
Aura Mesh: Motion Retargeting to Preserve the Spatial Relationships between Skinned Characters
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Applying motion-capture data to multi-person interaction between virtual characters is challenging because one needs to preserve the interaction semantics while also satisfying the general requirements of motion retargeting, ... -
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 ... -
String Art: Towards Computational Fabrication of String Images
(The Eurographics Association and John Wiley & Sons Ltd., 2018)In this paper we propose a novel method for the automatic computation and digital fabrication of artistic string images. String art is a technique used by artists for the creation of abstracted images which are composed ... -
Semantic Segmentation for Line Drawing Vectorization Using Neural Networks
(The Eurographics Association and John Wiley & Sons Ltd., 2018)In this work, we present a method to vectorize raster images of line art. Inverting the rasterization procedure is inherently ill-conditioned, as there exist many possible vector images that could yield the same raster ... -
Deep Joint Design of Color Filter Arrays and Demosaicing
(The Eurographics Association and John Wiley & Sons Ltd., 2018)We present a convolutional neural network architecture for performing joint design of color filter array (CFA) patterns and demosaicing. Our generic model allows the training of CFAs of arbitrary sizes, optimizing each ... -
Fast Catmull-Rom Spline Interpolation for High-Quality Texture Sampling
(The Eurographics Association and John Wiley & Sons Ltd., 2018)It is well known that cubic texture filtering can be efficiently implemented on the GPU by using a method published by Sigg and Hadwiger [SH05], which simplifies the evaluation to a linear combination of linear texture ... -
Sequences with Low-Discrepancy Blue-Noise 2-D Projections
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Distributions of samples play a very important role in rendering, affecting variance, bias and aliasing in Monte-Carlo and Quasi-Monte Carlo evaluation of the rendering equation. In this paper, we propose an original sampler ... -
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 ... -
Example-based Authoring of Procedural Modeling Programs with Structural and Continuous Variability
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Procedural models are a powerful tool for quickly creating a variety of computer graphics content. However, authoring them is challenging, requiring both programming and artistic expertise. In this paper, we present a ... -
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 ... -
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 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 ... -
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 ... -
