Practical Line Rasterization for Multi-resolution Textures
(The Eurographics Association, 2014)Draping 2D vectorial information over a 3D terrain elevation model is usually performed by real-time rendering to texture. In the case of linear feature representation, there are several specific problems using the texturing ... -
Practical logarithmic rasterization for low-error shadow maps
(The Eurographics Association, 2007)Logarithmic shadow maps can deliver the same quality as competing shadow map algorithms with substantially less storage and bandwidth. We show how current GPU architectures can be modified incrementally to support rendering ... -
Practical Low‐Cost Recovery of Spectral Power Distributions
(Copyright © 2016 The Eurographics Association and John Wiley & Sons Ltd., 2016)Measuring the spectral power distribution of a light source, that is, the emission as a function of wavelength, typically requires the use of spectrophotometers or multi‐spectral cameras. Here, we propose a low‐cost system ... -
Practical Machine Learning for Rendering: From Research to Deployment
(The Eurographics Association, 2022)Applying machine learning to improve graphics rendering or asset pipelines is challenging. Practicalities such as proprietary datasets, network retraining, and deployment issues make it difficult to translate published ... -
A Practical Male Hair Aging Model
(The Eurographics Association, 2020)The modeling and rendering of hair in Computer Graphics have seen much progress in the last few years. However, modeling and rendering hair aging, visually seen as the loss of pigments, have not attracted the same attention. ... -
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 ... -
Practical Measurement-based Modeling and Rendering of Surface Diffraction
(2019)Computer graphics have evolved at a very fast pace over the last forty years. Most of the research in rendering has been focused on recreating visual effects that can be explained with geometric optics, such as reflections ... -
Practical Medial Axis Filtering for Occlusion-Aware Contours
(The Eurographics Association, 2015)We propose a filtering system for occlusion-aware contours. Given a point of view, we use the silhouette of a 3D shape from that point of view, its medial axis and a map of the occluded areas. Our filter is able to select ... -
A Practical Method for Animating Anisotropic Elastoplastic Materials
(The Eurographics Association and John Wiley & Sons Ltd., 2020)This paper introduces a simple method for simulating highly anisotropic elastoplastic material behaviors like the dissolution of fibrous phenomena (splintering wood, shredding bales of hay) and materials composed of large ... -
A Practical Method for High-Resolution Embedded Liquid Surfaces
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Combining high-resolution level set surface tracking with lower resolution physics is an inexpensive method for achieving highly detailed liquid animations. Unfortunately, the inherent resolution mismatch introduces several ... -
Practical Method to Estimate Fabric Mechanics from Metadata
(The Eurographics Association and John Wiley & Sons Ltd., 2024)Estimating fabric mechanical properties is crucial to create realistic digital twins. Existing methods typically require testing physical fabric samples with expensive devices or cumbersome capture setups. In this work, ... -
Practical Offline Rendering of Woven Cloth
(The Eurographics Association, 2016)The techniques for rendering woven cloth employed in a production environment often neglect many of the structural features of the fabric, as well as light-scattering processes that occur in the yarn. Research in this area ... -
Practical Parallel Rendering of Detailed Neuron Simulations
(The Eurographics Association, 2013)Parallel rendering of large polygonal models with transparency is challenging due to the need for alpha-correct blending and compositing, which is costly for very large models with high depth complexity and spatial overlap. ... -
Practical Path Guiding for Efficient Light-transport Simulation
(The Eurographics Association and John Wiley & Sons Ltd., 2017)We present a robust, unbiased technique for intelligent light-path construction in path-tracing algorithms. Inspired by existing path-guiding algorithms, our method learns an approximate representation of the scene's ... -
Practical Person-Specific Eye Rigging
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We present a novel parametric eye rig for eye animation, including a new multi-view imaging system that can reconstruct eye poses at submillimeter accuracy to which we fit our new rig. This allows us to accurately estimate ... -
Practical Ply-Based Appearance Modeling for Knitted Fabrics
(The Eurographics Association, 2021)Abstract Modeling the geometry and the appearance of knitted fabrics has been challenging due to their complex geometries and interactions with light. Previous surface-based models have difficulties capturing fine-grained ... -
