EXPERIENCES WITH NEW IMAGE COMPONENT ALGORITHMS
(The Eurographics Association, 1984)We present experiences and comparisons evaluating a fast algorithm for connected component labeling of quad- and octrees. The algorithm works without loss of efficiency on linear tree representations that may reside in ... -
Experiencing Art by Means of 3D Printed Replicas: Enriching the Interpretation of Pot Oiseau
(The Eurographics Association, 2019)Digitally fabricated artefacts or 3D replicas have the potential to enrich the interpretation of cultural assets by enhancing visitors' engagement with collections. However, it is still not well understood how replicas ... -
Experiencing High-Speed Slash Action in Virtual Reality Environment
(The Eurographics Association, 2022)When a user uses a hand controller to swing a virtual sword in a virtual space, the sword movement seems slow if the its trajectory reflects the input directly. We hypothesize that this is because we are accustomed to ... -
Experiencing Infrastructures Sharing for International Research Activities
(The Eurographics Association, 2014)The Visionair Project aims at the creation of a distributed infrastructure of technological facilities in Europe as a visible, attractive entry point towards research and experimentation in high level visualisation, virtual ... -
Experiência de Realidade Virtual Imersiva no Ambiente CaveHollowspace do Lousal
(The Eurographics Association, 2021)Este artigo descreve o ambiente de realidade virtual imersiva CaveH, instalado no Centro de Ciência Viva do Lousal, focando-se nas suas componentes e na sua concretização. Descreve também o processo de desenvolvimento ... -
Experiências com Ray Tracing. Necessidade de Arquitecturas Paralelas
(The Eurographics Association, 2023)O Ray Tracing e a Radiosity são as técnicas de síntese de imagens que, na actualidade, produzem imagens com maior grau de realismo. Um sistema CAD dotado com estas técnicas poderá ser de grande utilidade numa empresa, quer ... -
An Experiment in Algorithm Animation using SMALLTALK on a Macintosh

Experiment-based Modeling, Simulation and Validation of Interactions between VirtualWalkers
(ACM SIGGRAPH / Eurographics Association, 2009)An interaction occurs between two humans when they walk with converging trajectories. They need to adapt their motion in order to avoid and cross one another at respectful distance. This paper presents a model for solving ... -
Experimental Analysis of BRDF Models
(The Eurographics Association, 2005)The Bidirectional Reflectance Distribution Function (BRDF) describes the appearance of a material by its interaction with light at a surface point. A variety of analytical models have been proposed to represent BRDFs. ... -
Experimental Analysis of BSDF Models
(The Eurographics Association, 2017)The Bidirectional Scattering Distribution Function (BSDF) describes the appearance of an optically thin, translucent material by its interaction with light at a surface point. Various BSDF models have been proposed to ... -
An Experimental Comparison of Three Optical Trackers for Model Based Pose Determination in Virtual Reality
(The Eurographics Association, 2004)In recent years many optical trackers have been proposed for usage in Virtual Environments. In this paper, we compare three model based optical tracking algorithms for pose determination of input devices. In particular, ... -
Experimental Feedback on Prog and Play, a Serious Game for Programming Practice
(The Eurographics Association, 2010)This paper presents an experimental feedback on a serious game dedicated to strengthening programming skills. This serious game called Prog&Play is built on an open source realtime strategy game. Its goal is to be compatible ... -
Experimental Feedback on Prog and Play: A Serious Game for Programming Practice
(The Eurographics Association and Blackwell Publishing Ltd., 2011)This paper presents an experimental feedback on a serious game dedicated to strengthening programming skills. This serious game, called Prog&Play, is built on an open source real-time strategy game. Its goal is to be ... -
An Experimental Setup to Evaluate the Performance of Tone Mapping Algorithms
(The Eurographics Association, 2006)Many algorithms have been proposed in the literature to solve the problem of mapping tones from high dynamic range sources to low dynamics displays, while preserving the information conveyed by the original scene. Methods ... -
An Experimental Shape Matching Approach for Protein Docking
(The Eurographics Association, 2016)Proteins play a vital role in biological processes, with their function being largely determined by their structure. It is important to know what a protein binds, where it binds, how it binds, and what is its final ... -
Experimental Similarity Assessment for a Collection of Fragmented Artifacts
(The Eurographics Association, 2018)In the Visual Heritage domain, search engines are expected to support archaeologists and curators to address cross-correlation and searching across multiple collections. Archaeological excavations return artifacts that ... -
Experimental Study of Haptic Interface Considering Myoelectrical Activity
(The Eurographics Association, 2007)Many types of haptic interface for virtual reality have been proposed. These haptic interfaces mostly contain earth grounding linkages. In this study, we considered wearable haptic interfaces for improved flexibility. It ... -
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 ... -
