Photorealistic Material Editing Through Direct Image Manipulation
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Creating photorealistic materials for light transport algorithms requires carefully fine-tuning a set of material properties to achieve a desired artistic effect. This is typically a lengthy process that involves a trained ... -
Can't Invert the CDF? The Triangle-Cut Parameterization of the Region under the Curve
(The Eurographics Association and John Wiley & Sons Ltd., 2020)We present an exact, analytic and deterministic method for sampling densities whose Cumulative Distribution Functions (CDFs) cannot be inverted analytically. Indeed, the inverse-CDF method is often considered the way to ... -
Guided Fine-Tuning for Large-Scale Material Transfer
(The Eurographics Association and John Wiley & Sons Ltd., 2020)We present a method to transfer the appearance of one or a few exemplar SVBRDFs to a target image representing similar materials. Our solution is extremely simple: we fine-tune a deep appearance-capture network on the ... -
Practical Measurement and Reconstruction of Spectral Skin Reflectance
(The Eurographics Association and John Wiley & Sons Ltd., 2020)We present two practical methods for measurement of spectral skin reflectance suited for live subjects, and drive a spectral BSSRDF model with appropriate complexity to match skin appearance in photographs, including human ... -
An Adaptive BRDF Fitting Metric
(The Eurographics Association and John Wiley & Sons Ltd., 2020)We propose a novel image-driven fitting strategy for isotropic BRDFs. Whereas existing BRDF fitting methods minimize a cost function directly on the error between the fitted analytical BRDF and the measured isotropic BRDF ... -
Adaptive Matrix Completion for Fast Visibility Computations with Many Lights Rendering
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Several fast global illumination algorithms rely on the Virtual Point Lights framework. This framework separates illumination into two steps: first, propagate radiance in the scene and store it in virtual lights, then ... -
Deep Kernel Density Estimation for Photon Mapping
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Recently, deep learning-based denoising approaches have led to dramatic improvements in low sample-count Monte Carlo rendering. These approaches are aimed at path tracing, which is not ideal for simulating challenging light ... -
Practical Product Path Guiding Using Linearly Transformed Cosines
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Path tracing is now the standard method used to generate realistic imagery in many domains, e.g., film, special effects, architecture etc. Path guiding has recently emerged as a powerful strategy to counter the notoriously ... -
A Scalable and Production Ready Sky and Atmosphere Rendering Technique
(The Eurographics Association and John Wiley & Sons Ltd., 2020)We present a physically based method to render the atmosphere of a planet from ground to space views. Our method is cheap to compute and, as compared to previous successful methods, does not require any high dimensional ... -
Neural Denoising with Layer Embeddings
(The Eurographics Association and John Wiley & Sons Ltd., 2020)We propose a novel approach for denoising Monte Carlo path traced images, which uses data from individual samples rather than relying on pixel aggregates. Samples are partitioned into layers, which are filtered separately, ... -
Rendering 2020 CGF 39-4: Frontmatter

Canis: A High-Level Language for Data-Driven Chart Animations
(The Eurographics Association and John Wiley & Sons Ltd., 2020)In this paper, we introduce Canis, a high-level domain-specific language that enables declarative specifications of data-driven chart animations. By leveraging data-enriched SVG charts, its grammar of animations can be ... -
Infomages: Embedding Data into Thematic Images
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Recent studies have indicated that visually embellished charts such as infographics have the ability to engage viewers and positively affect memorability. Fueled by these findings, researchers have proposed a variety of ... -
Sublinear Time Force Computation for Big Complex Network Visualization
(The Eurographics Association and John Wiley & Sons Ltd., 2020)In this paper, we present a new framework for sublinear time force computation for visualization of big complex graphs. Our algorithm is based on the sampling of vertices for computing repulsion forces and edge sparsification ... -
v-plots: Designing Hybrid Charts for the Comparative Analysis of Data Distributions
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Comparing data distributions is a core focus in descriptive statistics, and part of most data analysis processes across disciplines. In particular, comparing distributions entails numerous tasks, ranging from identifying ... -
Sunspot Plots: Model-based Structure Enhancement for Dense Scatter Plots
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Scatter plots are a powerful and well-established technique for visualizing the relationships between two variables as a collection of discrete points. However, especially when dealing with large and dense data, scatter ... -
Evaluating Reordering Strategies for Cluster Identification in Parallel Coordinates
(The Eurographics Association and John Wiley & Sons Ltd., 2020)The ability to perceive patterns in parallel coordinates plots (PCPs) is heavily influenced by the ordering of the dimensions. While the community has proposed over 30 automatic ordering strategies, we still lack empirical ... -
SEEVis: A Smart Emergency Evacuation Plan Visualization System with Data-Driven Shot Designs
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Despite the significance of tracking human mobility dynamics in a large-scale earthquake evacuation for an effective first response and disaster relief, the general understanding of evacuation behaviors remains limited. ... -
SeqDynamics: Visual Analytics for Evaluating Online Problem-solving Dynamics
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Problem-solving dynamics refers to the process of solving a series of problems over time, from which a student's cognitive skills and non-cognitive traits and behaviors can be inferred. For example, we can derive a student's ... -
WarehouseVis: A Visual Analytics Approach to Facilitating Warehouse Location Selection for Business Districts
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Selecting a proper warehouse location serving to satisfy the demands of the goods from a certain business area is important to a successful retail business. However, the large solution space, uncertain traffic conditions, ...
