Hinted Star Coordinates for Mixed Data

Mixed data sets containing numerical and categorical attributes are nowadays ubiquitous. Converting them to one attribute type may lead to a loss of information. We present an approach for handling numerical and categorical ...

Image‐Based Tree Variations

The automatic generation of realistic vegetation closely reproducing the appearance of specific plant species is still a challenging topic in computer graphics. In this paper, we present a new approach to generate new tree ...

Interactive Iconized Grammar‐Based Pailou Modelling

Pailous are representative Chinese architectural works used for commemoration. However, their geometric structure and semantic construction rules are too complex for quick and intuitive modelling using traditional modelling ...

Making Parameter Dependencies of Time‐Series Segmentation Visually Understandable

This work presents an approach to support the visual analysis of parameter dependencies of time‐series segmentation. The goal is to help analysts understand which parameters have high influence and which segmentation ...

The Matchstick Model for Anisotropic Friction Cones

Inspired by frictional behaviour that is observed when sliding matchsticks against one another at different angles, we propose a phenomenological anisotropic friction model for structured surfaces. Our model interpolates ...

Memento: Localized Time‐Warping for Spatio‐Temporal Selection

Interaction techniques for temporal data are often focused on affecting the spatial aspects of the data, for instance through the use of transfer functions, camera navigation or clipping planes. However, the temporal aspect ...

Mesh Parametrization Driven by Unit Normal Flow

Zhao, Hui; Su, Kehua; Li, Chenchen; Zhang, Boyu; Yang, Lei; Lei, Na; Wang, Xiaoling; Gortler, Steven J.; Gu, Xianfeng (© 2020 Eurographics ‐ The European Association for Computer Graphics and John Wiley & Sons Ltd, 2020)

Based on mesh deformation, we present a unified mesh parametrization algorithm for both planar and spherical domains. Our approach can produce intermediate frames from the original meshes to the targets. We derive and ...

Microstructure Control in 3D Printing with Digital Light Processing

Luongo, A.; Falster, V.; Doest, M. B.; Ribo, M. M.; Eiriksson, E. R.; Pedersen, D. B.; Frisvad, J. R. (© 2020 Eurographics ‐ The European Association for Computer Graphics and John Wiley & Sons Ltd, 2020)

Digital light processing stereolithography is a promising technique for 3D printing. However, it offers little control over the surface appearance of the printed object. The printing process is typically layered, which ...

Multi‐Segment Foot for Human Modelling and Simulation

Realistic modelling of a human‐like character is one of the main topics in computer graphics to simulate human motion physically and also look realistically. Of the body parts, a human foot interacts with the ground, and ...

Muscle and Fascia Simulation with Extended Position Based Dynamics

Recent research on muscle and fascia simulation for visual effects relies on numerical methods such as the finite element method or finite volume method. These approaches produce realistic results, but require high ...

Normal‐Based Bas‐Relief Modelling via Near‐Lighting Photometric Stereo

We present a ear‐ighting hotometric tereo (NL‐PS) system to produce digital bas‐reliefs from a physical object (set) directly. Unlike both the 2D image and 3D model‐based modelling methods that require complicated interactions ...

On Demand Solid Texture Synthesis Using Deep 3D Networks

This paper describes a novel approach for on demand volumetric texture synthesis based on a deep learning framework that allows for the generation of high‐quality three‐dimensional (3D) data at interactive rates. Based on ...

Parameterization, Feature Extraction and Binary Encoding for the Visualization of Tree‐Like Structures

The study of vascular structures, using medical 3D models, is an active field of research. Illustrative visualizations have been applied to this domain in multiple ways. Researchers made the geometric properties of vasculature ...

Physically Based Real‐Time Rendering of Teeth and Partial Restorations

Visually accurate real‐time rendering of teeth has many applications ranging from computer games to dental computer aided design (CAD). Similar to skin, the realistic and physically correct appearance of teeth cannot be ...

PointCleanNet: Learning to Denoise and Remove Outliers from Dense Point Clouds

Point clouds obtained with 3D scanners or by image‐based reconstruction techniques are often corrupted with significant amount of noise and outliers. Traditional methods for point cloud denoising largely rely on local ...

Progressive Refinement Imaging

This paper presents a novel technique for progressive online integration of uncalibrated image sequences with substantial geometric and/or photometric discrepancies into a single, geometrically and photometrically consistent ...

RAS: A Data‐Driven Rigidity‐Aware Skinning Model For 3D Facial Animation

We present a novel data‐driven skinning model—rigidity‐aware skinning (RAS) model, for simulating both active and passive 3D facial animation of different identities in real time. Our model builds upon a linear blend ...

RayCaching: Amortized Isosurface Rendering for Virtual Reality

Real‐time virtual reality requires efficient rendering methods to deal with high‐ resolution stereoscopic displays and low latency head‐tracking. Our proposed RayCaching method renders isosurfaces of large volume datasets ...
