WEB3D

New acquisition and modeling tools make it easier to create 3D models, and affordable and powerful graphics hardware makes it easier to use them. As a result, the number of 3D models available on the web is increasing rapidly. However, it is still not ...

We consider the possibility of automatically modifying the user's viewpoint orientation for the purpose of enhancing the navigation experience. We concentrate on outdoor virtual environments where the terrain is uneven as well as certain cases of indoor ...

Many Web3D sites do not offer sufficient assistance to (especially novice) users in navigating the virtual world, find objects/places of interests, and learn how to interact with them. This paper aims at helping the Web3D content creator to face this ...

In order to generate 3D worlds in an automated way it is important to solve the problem of integrating existing 2D and 3D data automatically. We explain some of the issues of this problem in this paper. We also introduce mechanisms for automated ...

Since its inception, VRML has held out the promise of initiating a quantum leap in web deliverable content and applications. However, the promise has yet to be realized. In this paper, we consider the problem of the web-based delivery of instructions ...

A new category of devices, known as Personal Digital Assistant (PDA), has become increasingly widespread since the end of the nineties. A large number of software applications have been developed for PDAs, but high-quality 3D graphics still remain ...

We introduce WebCAME, a client/server multiresolution rendering system for progressive transmission and visualization of compressed non-manifold triangle meshes with texture and color. The tool is implemented as a web browser plugin built upon standard ...

One of the major challenges in Computer Graphics concerns the 3D representation and physically-based simulation of garments. In our research, we are working closely with the textile industry, investigating three different classes of problems. First, we ...

Recent Standards specifications offer important but underemployed techniques to maximize access-to and distribution-of information for real-time 3D visualization over the web. This paper describes and evaluates such techniques to transform structured ...

Embodied agents or humanoid avatars may effectively be used to communicate with human users. Currently there is a wide range of specification formalisms and scripting languages for embodied agents, many of which are of a somewhat ad hoc nature lacking ...

Success of 3D applications on the Web inherently depends on object behavior and interaction. Current Web3D formats often fall short in supporting behavior modeling. This paper introduces a flexible concept for declaratively modeling 3D object behaviors. ...

In this paper we present a VRML oriented framework that aims to capture the key notions that underlie the extension of X3D toward multiuser and autonomous creatures. Our results can be understood in two ways. One can view the structure of the framework ...

The INVIWO (Intuitive Virtual Worlds) platform enables the execution of virtual agents and avatars, whose behaviour can be described using the MARVIN synchronous language. In this paper, we focus on the visualization of INVIWO worlds; after a ...

Multi-user virtual environment (MUVE) systems integrate the technologies of virtual reality and distributed system to allow users to interact with each other in a realistic virtual environment. However, due to the inflexibility in the current message ...

In this paper, we present the design and implementation of the VRML97 Distributed Authoring Interface (DAI) introduced in Spin-3D, a distributed Collaborative Virtual Environment (CVE). Our proposal is a powerful interface, very close to the classical ...

We describe a Web based presentation system for dynamic object scenarios. The system produces multimodal presentations based on 3D interactive animations, coordinated with adaptive spoken comments. User profiling and comments production are performed ...

This paper presents the second edition of our multicast protocol designed to enable shared virtual worlds.This second release was undertaken to provide an interaction methodology with other participants of a shared virtual world. These virtual world ...

This paper describes a robust mechanism for transmitting 3D meshes over the Internet. TCP/IP is an excellent means for reliable transport over the Internet. However, multi-user, real-time graphics applications may find TCP transmission disadvantageous ...

Geometry compression for VRML has been an important item on the wish-list of the Web3D Consortium since 1996. It was widely understood that a binary format would be required to allow compressed geometry, which explains why there is still no geometry ...
