3D maps can visualize static and dynamic features of real environments, and act as 3D gateways to location-based information. Insufficient network speed has been a major bottleneck for dynamic download of 3D content for mobile devices. 3G network ...

Interactive visualization of large 3D architectural models on mobile devices such as PDAs would significantly benefit applications such as indoor navigators and mobile tourist guides, on-site monitoring and annotation of architectural designs at ...

In this paper, we explore and discuss X3D as an application description language for advanced mixed reality environments. X3D has been established as an important platform for today's web-based visualization and VR applications. Yet, there are very few ...

We describe a compressed multiresolution representation and a client-server architecture for supporting interactive high quality remote visualization of very large textured planar and spherical terrains. Our approach incrementally updates a chunked ...

This paper presents an improved client-server system that increases the availability of remote 3D data. In order to reduce the required bandwidth, the data related to the appearance (color and normal) involved in the rendering of meshes and point clouds ...

In this paper, a compression method of encoding/decoding 3D mesh based on octree is proposed. Vertices of the 3D mesh are reclassified according to the octree rule. We analyse all the nodes of the octree statistically to identify the type of nodes which ...

Shape inspection options in most of the current online shape repositories provide limited information on the shape of a desired model. In addition, stored models can be downloaded only at the original level of detail (LOD). In this paper, we present our ...

Sign languages are visual languages used by deaf people to communicate. As with spoken languages, sign languages vary among countries and have their own vocabulary and grammar. Therefore, the different deaf communities need a dictionary that associates ...

To understand the functional elements of a protein structure biologists use domain specific 3D viewers (PDB) that are written to process the coordinates of atoms that represent the solved protein structure using X-Ray crystallography or NMR. The PDB ...

The Integrated Situational Awareness System (ISAS) initiative at the University of Florida Digital Worlds Institute has demonstrated an effective web services-enhanced graphically-based environment for globally-distributed operations ranging from ...

Ontology visualization and exploration is not a trivial task as many issues can affect the effectiveness of interactions. As ontologies are, in the general case, quite connected graphs where concepts are the nodes and semantic relationships the edges, ...

3D data is democratizing on the Web as it becomes available to everybody on almost all access devices. Still, 3D data is a heavy medium, as it contains a lot of geometric and texture information. This complexity raises a lot of problems, especially when ...

We will give an overview of the COLLADA 1.4 standard physics format [1][2][3] and its use in the 3D physics content pipeline. We describe design decisions, implementation, compatibility and interoperability aspects of adopters of this industry standard, ...

In this paper we propose an alternative approach to create animations in X3D. This approach allows extended flexibility to control animations during run-time. Among the extended features, it is possible to: control the speed of the animation; play the ...

The VRML and X3D Standards have achieved success as a method for not only 3D Model Interchange, but also for creation of complex synthesized 3D worlds. Shortcomings in VRML and X3D exist in the areas of manipulation of aural soundscapes, and interaction ...

Distributed Virtual Environments (DVEs) are distributed, simulated virtual worlds where users gather and interact within a shared space. Web-based DVE applications are attracting more and more attention. However, building DVE applications requires a ...

This paper presents a grid-based large-scale web3D collaborative virtual environment that has the capability of scaling across multiple geographically dispersed resources. The architecture consists of distributed mobile agents working cooperatively in ...

This paper describes work to create an open protocol for wide-area multi-user X3D, incorporating many aspects of prior academic, experimental, and proprietary systems, but emphasizing simplicity and practicality for use among heterogeneous Internet user ...

Scientists regularly confront situations where they are trying to understand large quantities of information, that vary over time and space. Analyzing such systems where structure and function are related is still a challenge despite the continued ...

This paper describes two new three dimensional interface components (The Flow and Circulatory system). These components utilize the depth provided by 3D computer graphics to present complex information in a natural three dimensional form for user ...

In this paper we give a comprehensive overview of our work on digital dossiers for the presentation of cultural heritage, in particular contemporary art, on the web using standard 3D technology. Digital dossiers allow for navigation using concept-graphs,...

In this paper we present our experience in using Virtual Reality Technologies to accurately reconstruct and further explore ancient and historic city buildings. Virtual reality techniques provide a powerful set of tools to explore and access the history ...

In this paper, the novel 3D survey technique of laser scanning integrated with photogrammetric images is introduced as a quasi-automatic way for the detailed modeling and the virtual rendering of whole cities with complex geometries and structures.

Today CSCW systems are used in various scientific, economic, and industrial areas. The logical next step is that collaborators not only want to work together by sharing documents or by communicating via mail or chat. Rather it would be more interesting ...

There is currently a dramatic shift in the Architecture, Engineering, and Construction (AEC) industry to embrace Building Information Modeling (BIM) as a tool that can assist in integrating the fragmented industry by eliminating inefficiencies and ...

This paper describes a 3D environment for representing a university undergraduate education programme. More specifically, the curriculum data selected for representation, how they are visualized in the 3D environment, and the process of generating it ...

This paper presents first compression results on using the MPEG-4 BBA standard for encoding motion capture data. We first introduce a detailed description of the main compression mechanisms used in recently BBA standard: prediction, frequency transform, ...

In this paper we present a procedure to create animated human models, compliant with the H-Anim standard, from 3D CAESAR scan bodies, which were captured using a whole body scan device. We also present a VRML prototype of an "Animated CAESAR Viewer" to ...

This paper describes current work in the evolution of open standards for 3D graphics for Humanoid Animation (H-Anim). It builds on previous work to encompass plausible humanoids, humanoid behaviors and methodologies for composition with interchangeable ...
