Point-driven Generation of Images from a Hierarchical Data Structure
(The Eurographics Association, 1988)In this paper, a system IS described which renders an image from a hierarchical data structure in a point-driven way. The data structure allows dynamic color mapping and arbitrary affine transformat·ons of objects with ... -
Point-Pattern Synthesis using Gabor and Random Filters
(The Eurographics Association and John Wiley & Sons Ltd., 2022)Point pattern synthesis requires capturing both local and non-local correlations from a given exemplar. Recent works employ deep hierarchical representations from VGG-19 [SZ15] convolutional network to capture the features ... -
Point-wise Adaptive Filtering for Fast Monte Carlo Noise Reduction
(The Eurographics Association, 2012)Monte Carlo based photorealistic image synthesis has proven to be one of the most flexible and powerful rendering techniques, but is plagued with undesirable artifacts known as Monte Carlo noise. We present an adaptive ... -
Point-wise Map Recovery and Refinement from Functional Correspondence
(The Eurographics Association, 2015)Since their introduction in the shape analysis community, functional maps have met with considerable success due to their ability to compactly represent dense correspondences between deformable shapes. Despite the numerous ... -
PointAO - Improved Ambient Occlusion for Point-based Visualization
(The Eurographics Association, 2013)The visualization of large amounts of particles, glyphs, and other point-based data plays an important role in many fields of science, among them flow mechanics, molecular dynamics, and medical imaging. The proper perception ... -
PointCleanNet: Learning to Denoise and Remove Outliers from Dense Point Clouds
(© 2020 Eurographics ‐ The European Association for Computer Graphics and John Wiley & Sons Ltd, 2020)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 ... -
PointCloudSlicer: Gesture-based Segmentation of Point Clouds
(The Eurographics Association, 2023)Segmentation is a fundamental problem in point-cloud processing, addressing points classification into consistent regions, the criteria for consistency being based on the application. In this paper, we introduce a simple, ... -
PointCloudXplore: Visual Analysis of 3D Gene Expression Data Using Physical Views and Parallel Coordinates
(The Eurographics Association, 2006)To allow a more rigorous understanding of animal gene regulatory networks, the Berkeley Drosophila Transcription Network Project (BDTNP) has developed a suite of methods that support quantitative, computational analysis ... -
Pointillist and Glyph-based Visualization of Nanoparticles in Formation
(The Eurographics Association, 2005)In this paper we offer new, texture-based methods for the visualization of multivariate data. These methods aim to more effectively convey the results of calculations simulating the formation of nanoparticles in turbulent ... -
Pointing Facilitation Techniques for 3D Object Selection in Virtual Environments
(Argelaguet Sanz, 2011-07-04)Selection is one of the fundamental tasks in virtual reality applications and the initial task for most common user's interactions in a virtual environment. In this thesis we analyze major factors influencing selection ... -
PointProNets: Consolidation of Point Clouds with Convolutional Neural Networks
(The Eurographics Association and John Wiley & Sons Ltd., 2018)With the widespread use of 3D acquisition devices, there is an increasing need of consolidating captured noisy and sparse point cloud data for accurate representation of the underlying structures. There are numerous ... -
Points Reloaded: Point-Based Rendering Revisited
(The Eurographics Association, 2004)The increasing popularity of points as rendering primitives has led to a variety of different rendering algorithms, and in particular the different implementations compare like apples to oranges. In this paper we revisit ... -
PointSkelCNN: Deep Learning-Based 3D Human Skeleton Extraction from Point Clouds
(The Eurographics Association and John Wiley & Sons Ltd., 2020)A 3D human skeleton plays important roles in human shape reconstruction and human animation. Remarkable advances have been achieved recently in 3D human skeleton estimation from color and depth images via a powerful deep ... -
Pointwise radial minimization: Hermite interpolation on arbitrary domains
(The Eurographics Association and Blackwell Publishing Ltd, 2008)In this paper we propose a new kind of Hermite interpolation on arbitrary domains, matching derivative data of arbitrary order on the boundary. The basic idea stems from an interpretation of mean value interpolation as the ... -
PointWorks: Abstraction and Rendering of Sparsely Scanned Outdoor Environments
(The Eurographics Association, 2004)This paper describes a system, dubbed PointWorks, for rendering three-dimensionally digitized outdoor environments in non-photorealistic rendering styles. The challenge in rendering scanned outdoor environments is accommodating ... -
Poisson Image Analogy: Texture-Aware Seamless Cloning
(The Eurographics Association, 2013)Synthesizing two images with seamless boundaries, i.e. seamless image cloning, is important and has many useful applications in CG. Previous approaches do not produce realistic results if texture details of the two images ... -
Poisson Manifold Reconstruction - Beyond Co-dimension One
(The Eurographics Association and John Wiley & Sons Ltd., 2023)Screened Poisson Surface Reconstruction creates 2D surfaces from sets of oriented points in 3D (and can be extended to codimension one surfaces in arbitrary dimensions). In this work we generalize the technique to manifolds ... -
Poisson Surface Reconstruction
(The Eurographics Association, 2006)We show that surface reconstruction from oriented points can be cast as a spatial Poisson problem. This Poisson formulation considers all the points at once, without resorting to heuristic spatial partitioning or blending, ... -
Poisson Surface Reconstruction with Envelope Constraints
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Reconstructing surfaces from scanned 3D points has been an important research area for several decades. One common approach that has proven efficient and robust to noise is implicit surface reconstruction, i.e. fitting to ... -
Poisson-Based Weight Reduction of Animated Meshes
(The Eurographics Association and Blackwell Publishing Ltd, 2010)While animation using barycentric coordinates or other automatic weight assignment methods has become a popular method for shape deformation, the global nature of the weights limits their use for real-time applications. ...
