Accurate Synthesis of Multi-Class Disk Distributions
(The Eurographics Association and John Wiley & Sons Ltd., 2019)While analysing and synthesising 2D distributions of points has been applied both to the generation of textures with discrete elements and for populating virtual worlds with 3D objects, the results are often inaccurate ... -
Character Navigation in Dynamic Environments Based on Optical Flow
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Steering and navigation are important components of character animation systems to enable them to autonomously move in their environment. In this work, we propose a synthetic vision model that uses visual features to steer ... -
Clear Skies Ahead: Towards Real-Time Automatic Sky Replacement in Video
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Digital videos such as those captured by a smartphone often exhibit exposure inconsistencies, a poorly exposed sky, or simply suffer from an uninteresting or plain looking sky. Professionals may edit these videos using ... -
A CNN-based Flow Correction Method for Fast Preview
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Eulerian-based smoke simulations are sensitive to the initial parameters and grid resolutions. Due to the numerical dissipation on different levels of the grid and the nonlinearity of the governing equations, the differences ... -
Computational Design of Steady 3D Dissection Puzzles
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Dissection puzzles require assembling a common set of pieces into multiple distinct forms. Existing works focus on creating 2D dissection puzzles that form primitive or naturalistic shapes. Unlike 2D dissection puzzles ... -
Controlling Motion Blur in Synthetic Long Time Exposures
(The Eurographics Association and John Wiley & Sons Ltd., 2019)In a photo, motion blur can be used as an artistic style to convey motion and to direct attention. In panning or tracking shots, a moving object of interest is followed by the camera during a relatively long exposure. The ... -
Deep Fluids: A Generative Network for Parameterized Fluid Simulations
(The Eurographics Association and John Wiley & Sons Ltd., 2019)This paper presents a novel generative model to synthesize fluid simulations from a set of reduced parameters. A convolutional neural network is trained on a collection of discrete, parameterizable fluid simulation velocity ... -
Deep HDR Video from Sequences with Alternating Exposures
(The Eurographics Association and John Wiley & Sons Ltd., 2019)A practical way to generate a high dynamic range (HDR) video using off-the-shelf cameras is to capture a sequence with alternating exposures and reconstruct the missing content at each frame. Unfortunately, existing ... -
Deep Video-Based Performance Cloning
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We present a new video-based performance cloning technique. After training a deep generative network using a reference video capturing the appearance and dynamics of a target actor, we are able to generate videos where ... -
Dual Sheet Meshing: An Interactive Approach to Robust Hexahedralization
(The Eurographics Association and John Wiley & Sons Ltd., 2019)The combinatorial dual of a hex mesh induces a collection of mutually intersecting surfaces (dual sheets). Inspired by Campen et al.'s work on quad meshing [CBK12,CK14], we propose to directly generate such dual sheets so ... -
Dynamic Visibility-Driven Molecular Surfaces
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Molecular surface representations are an important tool for the visual analysis of molecular structure and function. In this paper, we present a novel method for the visualization of dynamic molecular surfaces based on the ... -
Elastic Correspondence between Triangle Meshes
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We propose a novel approach for shape matching between triangular meshes that, in contrast to existing methods, can match crease features. Our approach is based on a hybrid optimization scheme, that solves simultaneously ... -
Exact Constraint Satisfaction for Truly Seamless Parametrization
(The Eurographics Association and John Wiley & Sons Ltd., 2019)In the field of global surface parametrization a recent focus has been on so-called seamless parametrization. This term refers to parametrization approaches which, while using an atlas of charts to enable the handling of ... -
Exploratory Stage Lighting Design using Visual Objectives
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Lighting is a critical element of theater. A lighting designer is responsible for drawing the audience's attention to a specific part of the stage, setting time of day, creating a mood, and conveying emotions. Designers ... -
Generating Color Scribble Images using Multi-layered Monochromatic Strokes Dithering
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Color scribbling is a unique form of illustration where artists use compact, overlapping, and monochromatic scribbles at microscopic scale to create astonishing colorful images at macroscopic scale. The creation process ... -
Generating Stochastic Wall Patterns On-the-fly with Wang Tiles
(The Eurographics Association and John Wiley & Sons Ltd., 2019)The game and movie industries always face the challenge of reproducing materials. This problem is tackled by combining illumination models and various textures (painted or procedural patterns). Generating stochastic wall ... -
A Geometrically Consistent Viscous Fluid Solver with Two-Way Fluid-Solid Coupling
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We present a grid-based fluid solver for simulating viscous materials and their interactions with solid objects. Our method formulates the implicit viscosity integration as a minimization problem with consistently estimated ... -
Gradient Outlier Removal for Gradient-Domain Path Tracing
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We present a new outlier removal technique for a gradient-domain path tracing (G-PT) that computes image gradients as well as colors. Our approach rejects gradient outliers whose estimated errors are much higher than those ... -
Hierarchical Rasterization of Curved Primitives for Vector Graphics Rendering on the GPU
(The Eurographics Association and John Wiley & Sons Ltd., 2019)In this paper, we introduce the CPatch, a curved primitive that can be used to construct arbitrary vector graphics. A CPatch is a generalization of a 2D polygon: Any number of curves up to a cubic degree bound a primitive. ... -
Latent Space Physics: Towards Learning the Temporal Evolution of Fluid Flow
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We propose a method for the data-driven inference of temporal evolutions of physical functions with deep learning. More specifically, we target fluid flow problems, and we propose a novel LSTM-based approach to predict the ...
