This paper presents the latest advances and research in Computer Graphics education in a nutshell. It is concerned with topics that were presented at the Education Track of the Eurographics Conference held in Lisbon in ...

Enhancing the Realism of Sketch and Painted Portraits With Adaptable Patches

Realizing unrealistic faces is a complicated task that requires a rich imagination and comprehension of facial structures. When face matching, warping or stitching techniques are applied, existing methods are generally ...

Improved Corners with Multi‐Channel Signed Distance Fields

We propose an extension to the state‐of‐the‐art text rendering technique based on sampling a 2D signed distance field from a texture. This extension significantly improves the visual quality of sharp corners, which is the ...

Uniformization and Density Adaptation for Point Cloud Data Via Graph Laplacian

Point cloud data is one of the most common types of input for geometric processing applications. In this paper, we study the point cloud density adaptation problem that underlies many pre‐processing tasks of points data. ...

Guidelines for Quantitative Evaluation of Medical Visualizations on the Example of 3D Aneurysm Surface Comparisons

Medical visualizations are highly adapted to a specific medical application scenario. Therefore, many researchers conduct qualitative evaluations with a low number of physicians or medical experts to assess the benefits ...

Story Albums: Creating Fictional Stories From Personal Photograph Sets

We present a method for the automatic creation of fictional storybooks based on personal photographs. Unlike previous attempts that summarize such collections by picking salient or diverse photos, or creating personal ...

Easy Generation of Facial Animation Using Motion Graphs

Facial animation is a time‐consuming and cumbersome task that requires years of experience and/or a complex and expensive set‐up. This becomes an issue, especially when animating the multitude of secondary characters ...

Audiovisual Resource Allocation for Bimodal Virtual Environments

Fidelity is of key importance if virtual environments are to be used as authentic representations of real environments. However, simulating the multitude of senses that comprise the human sensory system is computationally ...

A Visualization Framework and User Studies for Overloaded Orthogonal Drawings

Overloaded orthogonal drawing (OOD) is a recent graph visualization style specifically conceived for directed graphs. It merges the advantages of some popular drawing conventions like layered drawings and orthogonal drawings, ...

A Survey on Multimodal Medical Data Visualization

Multi‐modal data of the complex human anatomy contain a wealth of information. To visualize and explore such data, techniques for emphasizing important structures and controlling visibility are essential. Such fused overview ...

ProactiveCrowd: Modelling Proactive Steering Behaviours for Agent‐Based Crowd Simulation

How to realistically model an agent's steering behaviour is a critical issue in agent‐based crowd simulation. In this work, we investigate some proactive steering strategies for agents to minimize potential collisions. To ...

Large‐Scale Pixel‐Precise Deferred Vector Maps

Rendering vector maps is a key challenge for high‐quality geographic visualization systems. In this paper, we present a novel approach to visualize vector maps over detailed terrain models in a pixel‐precise way. Our method ...

A Physically Consistent Implicit Viscosity Solver for SPH Fluids

Weiler, Marcel; Koschier, Dan; Brand, Magnus; Bender, Jan (The Eurographics Association and John Wiley & Sons Ltd., 2018)

In this paper, we present a novel physically consistent implicit solver for the simulation of highly viscous fluids using the Smoothed Particle Hydrodynamics (SPH) formalism. Our method is the result of a theoretical and ...

Repairing Inconsistent Curve Networks on Non-parallel Cross-sections

Huang, Zhi Yang; Holloway, Michelle; Carr, Nathan; Ju, Tao (The Eurographics Association and John Wiley & Sons Ltd., 2018)

In this work we present the first algorithm for restoring consistency between curve networks on non-parallel cross-sections. Our method addresses a critical but overlooked challenge in the reconstruction process from ...

PointProNets: Consolidation of Point Clouds with Convolutional Neural Networks

Roveri, Riccardo; Öztireli, A. Cengiz; Pandele, Ioana; Gross, Markus (The Eurographics Association and John Wiley & Sons Ltd., 2018)

Wavejets: A Local Frequency Framework for Shape Details Amplification

Béarzi, Yohann; Digne, Julie; Chaine, Raphaëlle (The Eurographics Association and John Wiley & Sons Ltd., 2018)

Detail enhancement is a well-studied area of 3D rendering and image processing, which has few equivalents for 3D shape processing. To enhance details, one needs an efficient analysis tool to express the local surface ...

A New Microflake Model With Microscopic Self-shadowing for Accurate Volume Downsampling

Loubet, Guillaume; Neyret, Fabrice (The Eurographics Association and John Wiley & Sons Ltd., 2018)

Naive linear methods for downsampling high-resolution microflake volumes often produce inaccurate appearance, especially when input voxels are very opaque. Preserving correct appearance at all resolutions requires taking ...
