Position Based Dynamics
(The Eurographics Association, 2006)The most popular approaches for the simulation of dynamic systems in computer graphics are force based. Internal and external forces are accumulated from which accelerations are computed based on Newton's second law of ... -
"Position Paper:Display Hardware for Boolean Expression Models"
(The Eurographics Association, 1986)In any discussion of graphics hardware there appear to be two basic positions which can be adopted. The first is that of the technologist, who is primarily concerned with what it is possible to make and how to make it. The ... -
Position-based Elastic Rods
(The Eurographics Association, 2014)We present a novel method to simulate complex bending and twisting of elastic rods. Elastic rods are commonly simulated using force based methods, such as the finite element method. These methods are accurate, but do not ... -
Position-based Methods for the Simulation of Solid Objects in Computer Graphics
(The Eurographics Association, 2013)The dynamic simulation of solids has a long history in computer graphics. The classical methods in this field are based on the use of forces or impulses to simulate joints between rigid bodies as well as the stretching, ... -
Position-Based Multi-Agent Dynamics for Real-Time Crowd Simulation
(ACM, 2017)Exploiting the e ciency and stability of Position-Based Dynamics (PBD), we introduce a novel crowd simulation method that runs at interactive rates for hundreds of thousands of agents. Our method enables the detailed ... -
Position-Based Simulation Methods in Computer Graphics
(The Eurographics Association, 2015)The physically-based simulation of mechanical effects has been an important research topic in computer graphics for more than two decades. Classical methods in this field discretize Newton’s second law and determine different ... -
Position-Based Simulation of Elastic Models on the GPU with Energy Aware Gauss-Seidel Algorithm
(The Eurographics Association and John Wiley & Sons Ltd., 2019)In this paper, we provide a smooth extension of the energy aware Gauss-Seidel iteration to the Position-Based Dynamics (PBD) method. This extension is inspired by the kinetic and potential energy changes equalization and ... -
Position-based Skin Deformations for Interactive Character Animation
(2016-03-03)Skeletal animation is a widely used technique for animating articulated characters, such as humans and animals. In skeleton-based animation, skinning is the process of defining how the geometric surface of the character ... -
A Position-Free Path Integral for Homogeneous Slabs and Multiple Scattering on Smith Microfacets
(The Eurographics Association and John Wiley & Sons Ltd., 2022)We consider the problem of multiple scattering on Smith microfacets. This problem is equivalent to computing volumetric light transport in a homogeneous slab. Although the symmetry of the slab allows for significant ... -
Positional, Metric, and Curvature Control for Constraint-Based Surface Deformation
(The Eurographics Association and Blackwell Publishing Ltd, 2009)We present a geometry processing framework that allows direct manipulation or preservation of positional, metric, and curvature constraints anywhere on the surface of a geometric model. Target values for these properties ... -
Positioning of Subtitles in Cinematic Virtual Reality
(The Eurographics Association, 2018)Cinematic Virtual Reality has been increasing in popularity in recent years.Watching 360 degree movies with a head mounted display, the viewer can freely choose the direction of view and thus the visible section of the ... -
Position‐Based Skinning for Soft Articulated Characters
(Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)In this paper, we introduce a two‐layered approach addressing the problem of creating believable mesh‐based skin deformation. For each frame, the skin is first deformed with a classic linear blend skinning approach, which ... -
A Positive-Definite Cut-Cell Method for Strong Two-Way Coupling Between Fluids and Deformable Bodies
(ACM, 2017)We present a new approach to simulation of two-way coupling between inviscid free surface fluids and deformable bodies that exhibits several notable advantages over previous techniques. By fully incorporating the dynamics ... -
Possibilities and Challenges of Portraying Cultural Heritage Artefacts using Augmented Reality: the Mjällby Crucifix Case Study
(The Eurographics Association, 2020)The increasing application of immersive technologies, i.e. virtual reality (VR) and augmented reality (AR), in cultural heritage (CH) offers new ways of displaying artefacts and historical sites. VR and AR provide an added ... -
PossibleImpossibles: Exploratory Procedural Design of Impossible Structures
(The Eurographics Association and John Wiley & Sons Ltd., 2024)We present a method for generating structures in three-dimensional space that appear to be impossible when viewed from specific perspectives. Previous approaches focus on helping users to edit specific structures and require ... -
Post Facto Registration Tools for Urban Modelling
(The Eurographics Association, 2008)Urban modelling applications require high-precision geometric models both for graphical rendering and for engineering purposes. While geometric models, photographic images and laser-scanned point clouds are ideally ... -
A Post Processing Technique to Automatically Remove Floater Artifacts in Neural Radiance Fields
(The Eurographics Association and John Wiley & Sons Ltd., 2023)Neural Radiance Fields have revolutionized Novel View Synthesis by providing impressive levels of realism. However, in most in-the-wild scenes they suffer from floater artifacts that occur due to sparse input images or ... -
Post-Convolved Splatting
(The Eurographics Association, 2003)One of the most expensive operations in volume rendering is the interpolation of samples in volume space. The number of samples, in turn, depends on the resolution of the final image. Hence, viewing the volume at high ... -
Post-processing of Scanned 3D Surface Data
(The Eurographics Association, 2004)3D shape acquisition has become a major tool for creating digital 3D surface data in a variety of application elds. Despite the steady increase in accuracy, most available scanning techniques cause severe scanning artifacts ... -
Post-rendering Composition for 3D Scenes
(Eurographics Association, 2001)In traditional art a painter displays a 3D scene on a 2D image plane in a manner that is aesthetically pleasing. The arrangement of objects and colors is called composition and is the subject of many art books and classes. ...
