Geometric Flows of Curves in Shape Space for Processing Motion of Deformable Objects
(The Eurographics Association and John Wiley & Sons Ltd., 2016)We introduce techniques for the processing of motion and animations of non-rigid shapes. The idea is to regard animations of deformable objects as curves in shape space. Then, we use the geometric structure on shape space ... -
A Multi-sided Bézier Patch with a Simple Control Structure
(The Eurographics Association and John Wiley & Sons Ltd., 2016)A new n-sided surface scheme is presented, that generalizes tensor product Bézier patches. Boundaries and corresponding crossderivatives are specified as conventional Bézier surfaces of arbitrary degrees. The surface is ... -
A Practical and Controllable Hair and Fur Model for Production Path Tracing
(The Eurographics Association and John Wiley & Sons Ltd., 2016)We present an energy-conserving fiber shading model for hair and fur that is efficient enough for path tracing. Our model adopts a near-field formulation to avoid the expensive integral across the fiber, accounts for all ... -
SAH Guided Spatial Split Partitioning for Fast BVH Construction
(The Eurographics Association and John Wiley & Sons Ltd., 2016)We present a new SAH guided approach to subdividing triangles as the scene is coarsely partitioned into smaller sets of spatially coherent triangles. Our triangle split approach is integrated into the partitioning stage ... -
Regularizing Image Reconstruction for Gradient-Domain Rendering with Feature Patches
(The Eurographics Association and John Wiley & Sons Ltd., 2016)We present a novel algorithm to reconstruct high-quality images from sampled pixels and gradients in gradient-domain rendering. Our approach extends screened Poisson reconstruction by adding additional regularization ... -
Multi-Resolution Meshes for Feature-Aware Hardware Tessellation
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Hardware tessellation is de facto the preferred mechanism to adaptively control mesh resolution with maximal performances. However, owing to its fixed and uniform pattern, leveraging tessellation for feature-aware LOD ... -
Stylized Caustics: Progressive Rendering of Animated Caustics
(The Eurographics Association and John Wiley & Sons Ltd., 2016)In recent years, much work was devoted to the design of light editing methods such as relighting and light path editing. So far, little work addressed the target-based manipulation and animation of caustics, for instance ... -
A Practical Method for High-Resolution Embedded Liquid Surfaces
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Combining high-resolution level set surface tracking with lower resolution physics is an inexpensive method for achieving highly detailed liquid animations. Unfortunately, the inherent resolution mismatch introduces several ... -
Narrow Band FLIP for Liquid Simulations
(The Eurographics Association and John Wiley & Sons Ltd., 2016)The Fluid Implicit Particle method (FLIP) for liquid simulations uses particles to reduce numerical dissipation and provide important visual cues for events like complex splashes and small-scale features near the liquid ... -
Boundary Detection in Particle-based Fluids
(The Eurographics Association and John Wiley & Sons Ltd., 2016)This paper presents a novel method to detect free-surfaces on particle-based volume representation. In contrast to most particlebased free-surface detection methods, which perform the surface identification based on physical ... -
Smooth Image Sequences for Data-driven Morphing
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Smoothness is a quality that feels aesthetic and pleasing to the human eye. We present an algorithm for finding ''as-smoothas- possible'' sequences in image collections. In contrast to previous work, our method does not ... -
DeepProp: Extracting Deep Features from a Single Image for Edit Propagation
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Edit propagation is a technique that can propagate various image edits (e.g., colorization and recoloring) performed via user strokes to the entire image based on similarity of image features. In most previous work, users ... -
Sparse Representation of Terrains for Procedural Modeling
(The Eurographics Association and John Wiley & Sons Ltd., 2016)In this paper, we present a simple and efficient method to represent terrains as elevation functions built from linear combinations of landform features (atoms). These features can be extracted either from real world ... -
Large Scale Terrain Generation from Tectonic Uplift and Fluvial Erosion
(The Eurographics Association and John Wiley & Sons Ltd., 2016)At large scale, landscapes result from the combination of two major processes: tectonics which generate the main relief through crust uplift, and weather which accounts for erosion. This paper presents the first method in ... -
Convolutional Sparse Coding for High Dynamic Range Imaging
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Current HDR acquisition techniques are based on either (i) fusing multibracketed, low dynamic range (LDR) images, (ii) modifying existing hardware and capturing different exposures simultaneously with multiple sensors, or ... -
An Objective Deghosting Quality Metric for HDR Images
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Reconstructing high dynamic range (HDR) images of a complex scene involving moving objects and dynamic backgrounds is prone to artifacts. A large number of methods have been proposed that attempt to alleviate these artifacts, ... -
Character Contact Re-positioning Under Large Environment Deformation
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Character animation based on motion capture provides intrinsically plausible results, but lacks the flexibility of procedural methods. Motion editing methods partially address this limitation by adapting the animation to ... -
Animation Setup Transfer for 3D Characters
(The Eurographics Association and John Wiley & Sons Ltd., 2016)We present a general method for transferring skeletons and skinning weights between characters with distinct mesh topologies. Our pipeline takes as inputs a source character rig (consisting of a mesh, a transformation ... -
Motion Grammars for Character Animation
(The Eurographics Association and John Wiley & Sons Ltd., 2016)The behavioral structure of human movements is imposed by multiple sources, such as rules, regulations, choreography, habits, and emotion. Our goal is to identify the behavioral structure in a specific application domain ... -
Automatic Portrait Segmentation for Image Stylization
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Portraiture is a major art form in both photography and painting. In most instances, artists seek to make the subject stand out from its surrounding, for instance, by making it brighter or sharper. In the digital world, ...
