Experimenting Prioritized IK for Motion Editing
(Eurographics Association, 2003)The presented work illustrates the potential of an IK algorithm enforcing priorities among constraints for motion editing. Motion capture is a very efficient technique to deliver believable motions but usually most of the ... -
Experimenting with a Parallel Ray-Tracing Algorithm on a Hypercube Machine
(Eurographics Association, 1988)A parallel space tracing algorithm is presented. It subdivides the scene into regions. These latter are distributed among the processors of an iPSC hypercube machine designed by Intel company. Each processor subdivides its ... -
Experiments in the Parallel Computation of 3D Convex Hulls
(Blackwell Science Ltd and the Eurographics Association, 1994)Two parallel implementations of a 3D convex hull algorithm are reported. The paper considers a MIMD distributed memory architecture and the implementations are carried out on the Meiko Computing Surface using T800 transputers ... -
Experiments on the Accuracy of Feature Extraction
(The Eurographics Association, 1998)Feature extraction is an approach to visualization that ex- tracts important regions or objects of interest algorithmically from large data sets. In our feature extraction process, high-level attributes are cal- culated ... -
An Expert System for Polyhedra Modelling
(Eurographics Association, 1988)Very often we wish to construct shapes according to some criteria, which are properties we want the object to possess. In this case explicit construction becomes an inadapted way of working. One would wish to obtain the ... -
Explaining Black Box with Visual Exploration of Latent Space
(The Eurographics Association, 2022)Autoencoders are a powerful yet opaque feature reduction technique, on top of which we propose a novel way for the joint visual exploration of both latent and real space. By interactively exploiting the mapping between ... -
Explaining Neighborhood Preservation for Multidimensional Projections
(The Eurographics Association, 2015)Dimensionality reduction techniques are the tools of choice for exploring high-dimensional datasets by means of low-dimensional projections. However, even state-of-the-art projection methods fail, up to various degrees, ... -
ExPlates: Spatializing Interactive Analysis to Scaffold Visual Exploration
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Visual exploration involves using visual representations to investigate data where the goals of the process are unclear and poorly defined. However, this often places unduly high cognitive load on the user, particularly ... -
Explicit Adaptive Tessellation based on re-parametrization on Graphics Hardware
(The Eurographics Association, 2007)We propose to use an explicit function for adaptive tessellation of parametric curves and surfaces. This function behaves as a new parametrization from the surface domain (or curve domain) to the domain itself; it is build ... -
Explicit Cache Management for Volume Ray-Casting on Parallel Architectures
(The Eurographics Association, 2012)A major challenge when designing general purpose graphics hardware is to allow efficient access to texture data. Although different rendering paradigms vary with respect to their data access patterns, there is no flexibility ... -
Explicit Integrators Analysis for a Simulation Engine
(The Eurographics Association, 2006)One of the most significant elements when dealing with particle based object modeling in virtual reality applications is the integrator used to compute the state of the particles, because it grants the deformation stability ... -
Explicit Mesh Surfaces for Particle Based Fluids
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We introduce the idea of using an explicit triangle mesh to track the air/fluid interface in a smoothed particle hydrodynamics (SPH) simulator. Once an initial surface mesh is created, this mesh is carried forward in time ... -
An Explicit Structure-preserving Numerical Scheme for EPDiff
(The Eurographics Association and John Wiley & Sons Ltd., 2018)We present a new structure-preserving numerical scheme for solving the Euler-Poincaré Differential (EPDiff) equation on arbitrary triangle meshes. Unlike existing techniques, our method solves the difficult non-linear ... -
Explicit Surface Remeshing
(The Eurographics Association, 2003)We present a new remeshing scheme based on the idea of improving mesh quality by a series of local modifications of the mesh geometry and connectivity. Our contribution to the family of local modification techniques is an ... -
Exploiting Artistic Cues to obtain Line Labels for Free-hand Sketches
(The Eurographics Association, 2012)Artistic cues help designers to communicate design intent in sketches. In this paper, we show how these artistic cues may be used to obtain a line labelling interpretation of freehand sketches, using a cue-based genetic ... -
Exploiting Budan-Fourier and Vincent's Theorems for Ray Tracing 3D Bézier Curves
(ACM, 2017)We present a new approach to finding ray-cubic Bézier curve intersections by leveraging recent achievements in polynomial studies. Compared with the state-of-the-art adaptive linearization, it increases performance by 5-50 ... -
Exploiting Coherence in Lighting and Shading Computations
(Herzog, Robert, 2010-07-01)Computing global illumination (GI) in virtual scenes becomes increasingly attractive even for real-time applications nowadays. GI delivers important cues inthe perception of 3D virtual scenes, which is important for material ... -
Exploiting Local Orientation Similarity for Efficient Ray Traversal of Hair and Fur
(The Eurographics Association, 2014)Hair and fur typically consist of a large number of thin, curved, and densely packed strands which are difficult to ray trace efficiently. A tight fitting spatial data structure, such as a bounding volume hierarchy (BVH), ... -
Exploiting Neighboring Pixels Similarity for Effective SV-BRDF Reconstruction from Sparse MLICs
(The Eurographics Association, 2021)We present a practical solution to create a relightable model from Multi-light Image Collections (MLICs) acquired using standard acquisition pipelines. The approach targets the difficult but very common situation in which ... -
Exploiting Parallelism in Physically-Based Simulations on Multi-Core Processor Architectures
(The Eurographics Association, 2007)As multi-core processor systems become more and more widespread, the demand for designing efficient parallel algorithms propagates also into the field of computer graphics. This is especially true for the physically-based ...
