PPSurf: Combining Patches and Point Convolutions for Detailed Surface Reconstruction
(© 2024 Eurographics ‐ The European Association for Computer Graphics and John Wiley & Sons Ltd., 2024)3D surface reconstruction from point clouds is a key step in areas such as content creation, archaeology, digital cultural heritage and engineering. Current approaches either try to optimize a non‐data‐driven surface ... -
Practical Acquisition of Shape and Plausible Appearance of Reflective and Translucent Objects
(The Eurographics Association and John Wiley & Sons Ltd., 2023)We present a practical method for acquisition of shape and plausible appearance of reflective and translucent objects for realistic rendering and relighting applications. Such objects are extremely challenging to scan with ... -
A Practical Analysis of Clustering Strategies for Hierarchical Radiosity
(Blackwell Publishers Ltd and the Eurographics Association, 1999)The calculation of radiant energy balance in complex scenes has been made possible by hierarchical radiosity methods based on clustering mechanisms. Although clustering offers an elegant theoretical solution by reducing ... -
A Practical Analysis of Clustering Strategies for Hierarchical Radiosity (Supplementary material)

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 ... -
A Practical and Efficient Approach for Correct Z-Pass Stencil Shadow Volumes
(The Eurographics Association, 2019)Shadow volumes are a popular technique to compute pixel-accurate hard shadows in 3D scenes. Many variants exist that trade off accuracy and efficiency. In this work, we present an artifact-free, efficient, and easy-to-implement ... -
A Practical and Hierarchical Yarn-based Shading Model for Cloth
(The Eurographics Association and John Wiley & Sons Ltd., 2023)Realistic cloth rendering is a longstanding challenge in computer graphics due to the intricate geometry and hierarchical structure of cloth: Fibers form plies which in turn are combined into yarns which then are woven or ... -
Practical and Robust MLS-based Integration of Scanned Data
(The Eurographics Association, 2008)The paper proposes a set of techniques for improving the quality of MLS surfaces reconstructed from point clouds that are composed by the union of many scanned range maps. The main idea of those techniques is that the ... -
Practical Animation of Compressible Flow for ShockWaves and Related Phenomena
(The Eurographics Association, 2010)We propose a practical approach to integrating shock wave dynamics into traditional smoke simulations. Previous methods either simplify away the compressible component of the flow and are unable to capture shock fronts or ... -
Practical Animation of Turbulent Splashing Water
(The Eurographics Association, 2006)Despite recent advances in fluid animation, producing small-scale detail of turbulent water still remains challenging. In this paper, we extend the well-accepted particle level set method in an attempt to integrate the ... -
Practical Anisotropic Geodesy
(The Eurographics Association and Blackwell Publishing Ltd., 2013)The computation of intrinsic, geodesic distances and geodesic paths on surfaces is a fundamental low-level building block in countless Computer Graphics and Geometry Processing applications. This demand led to the development ... -
A Practical Approach to Physically-Based Reproduction of Diffusive Cosmetics
(The Eurographics Association and John Wiley & Sons Ltd., 2018)In this paper, we introduce so-called the bSX method as a new way to utilize the Kubelka-Munk (K-M) model. Assuming the material is completely diffusive, the K-M model gives the reflectance and transmittance of the material ... -
A Practical Approach to Provenance Capturing for Reproducible Visual Analytics at an Ocean Research Institute
(The Eurographics Association, 2023)Reproducibility - and the lack thereof - has been an important topic for some time in the field of Human-Computer Interaction. Visual analytics workflows and in extension immersive analytics workflows are no exception there ... -
Practical Calibration Procedures for Augmented Reality
(The Eurographics Association, 2000)Augmented Reality overlays computer generated images over the real world. This requires precise knowledge of the viewing projection of the headmounted display (HMD) and its position. Most of the previously published methods ... -
Practical Capture and Reproduction of Phosphorescent Appearance
(The Eurographics Association and John Wiley & Sons Ltd., 2017)This paper proposes a pipeline to accurately acquire, efficiently reproduce and intuitively manipulate phosphorescent appearance. In contrast to common appearance models, a model of phosphorescence needs to account for ... -
Practical CFD Simulations on Programmable Graphics Hardware using SMAC
(The Eurographics Association and Blackwell Publishing Ltd., 2005)The explosive growth in integration technology and the parallel nature of rasterization-based graphics APIs (Application Programming Interface) changed the panorama of consumer-level graphics: today, GPUs (Graphics Processing ... -
Practical Color-Based Motion Capture
(The Eurographics Association, 2011)Motion capture systems have been widely used for high quality content creation and virtual reality but are rarely used in consumer applications due to their price and setup cost. In this paper, we propose a motion capture ... -
Practical Computation of the Cut Locus on Discrete Surfaces
(The Eurographics Association and John Wiley & Sons Ltd., 2021)We present a novel method to compute the cut locus of a distance function encoded on a polygonal mesh. Our method exploits theoretical findings about the cut locus and - with a combination of analytic, geometric and ...
