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 ... -
A Practical Dynamics System
(The Eurographics Association, 2003)We present an effective production-proven dynamics system. It uses an explicit time differencing method that is efficient, reasonably accurate, conditionally stable, and above all simple to implement. We describe issues ... -
Practical Experiences with Using Autocollimator for Surface Reflectance Measurement
(The Eurographics Association, 2016)We present our experiences with using an autocollimator to set up the surface reflectance measurement for both BRDF and BTF. Assuming the measured material appearance is put on a locally flat surface, the autocollimator ... -
Practical Fabrication of Discrete Chebyshev Nets
(The Eurographics Association and John Wiley & Sons Ltd., 2020)We propose a computational and practical technique to allow home users to fabricate discrete Chebyshev nets for various 3D models. The success of our method relies on two key components. The first one is a novel and simple ... -
Practical Face Reconstruction via Differentiable Ray Tracing
(The Eurographics Association and John Wiley & Sons Ltd., 2021)We present a differentiable ray-tracing based novel face reconstruction approach where scene attributes - 3D geometry, reflectance (diffuse, specular and roughness), pose, camera parameters, and scene illumination - are ... -
Practical Foldover-Free Volumetric Mapping Construction
(The Eurographics Association and John Wiley & Sons Ltd., 2019)In this paper, we present a practically robust method for computing foldover-free volumetric mappings with hard linear constraints. Central to this approach is a projection algorithm that monotonically and efficiently ... -
Practical Free-form RTI Acquisition with Local Spot Lights
(The Eurographics Association, 2016)We present an automated light calibration pipeline for free-form acquisition of shape and reflectance of objects using common off-the-shelf illuminators, such as LED lights, that can be placed arbitrarily close to the ... -
A Practical GPU-accelerated Method for the Simulation of Naval Objects on Irregular Waves
(The Eurographics Association, 2016)This paper introduce a new method for real-time simulation of naval objects (such as vessels, ships, buoys and lifejackets) with six degrees of freedom on irregular waves. Thus method is based on hydrodynamic and hydrostatic ... -
