Modeling is used to build structures that serve as surrogates for other objects. As children, we learn to model at a very young age. An object such as a small toy train teaches us about the structure and behavior of an actual train. VRML is a file ...

The work presented in this paper is part of a Virtual Reality Research Project of the Heinz Nixdorf Institut and the Siemens AG KWU.

GeoVRML 1.0 provides geoscientists with a rich suite of enabling capabilities that cannot be found elsewhere. That is, the ability to model dynamic 3-D geographic data that can be distributed over the web and interactively visualized using a standard ...

We discuss potential and limitations of a Morph Node, inspired by the corresponding construct in Java3D. A Morph Node in Java3D interpolates vertex attributes among several homeomorphic geometries. This node is a promising candidate for the delivery of ...

In the days of VRML 1.0, NURBS seemed to be too complex to be adapted to the specification. Current development of hardware compels us to reevaluate this idea: While CPU clocks break the 1-GHz barrier, users still have to cope with 56K modems. NURBS ...

Computer graphics systems and CAD/CAM systems are widely used and an abundance of 3D-Data in various fields exists. However, based on the VRML technique, it is difficult to send such 3D-Data through the Internet, because of the large data size. ...

This paper describes the implementation of the Mu3D application protocol and consistency control mechanisms to allow the collaborative editing of CAD design. The collaborative editor (M3D editor) developed by us is VRML compliant. The editor has been ...

While three dimensional collaborative environments have been used for industrial design or interactive games, workgroup collaboration has largely remained in the two-dimensional realm. In this paper, we examine the collaborative capabilities of the ...

This paper deals with the question how the component idea can be transferred to the authoring of 3D content for the WWW. The concept of 3D Beans and their according authoring environment is presented. In addition, an implementation of this concept using ...

The Genetic Sculpture Park seeks to blur the distinction between artist and observer and to empower the novice in the creation of complex computer graphic models. Each visitor to the park experiences a unique set of forms and engages in a co-operative ...

In this paper we discuss the benefits of extending VRML by constraints and present a new way based on prototypes and scripting to implement this extension. Our approach is easy-to-use, extensible and it considerably increases the expressivity of VRML. ...

A technology that enables development of functional and interactive 3D product design models for web based environments is presented. A novel prototyping feature of these models is that they have capabilities to simulate complicated functions of the ...

When distributing 3D contents real-time over a network with a narrow bandwidth such as a telephone line, methods for streaming and data compression can be considered indispensable.

In previous work, we made possible the real-time streaming of 3D ...

This paper presents a multicast approach to shared virtual worlds. A shared VRML world is described with integrated spatial audio in a freeware VRML browser. An implementation in Linux of multicast FreeWRL with the Robust Audio Tool (RAT) is presented. ...

In this paper we want to analyze how the high-level languages Java and VRML can be used for 3D medical imaging and simulation on a PC. We want to compare two different approaches to use Java combined with VRML. One approach is to use Java locally inside ...

This paper describes initial research using the Virtual Reality Modeling Language (VRML97) in construction industry applications. The modeling of steel structures and construction equipment as objects for inclusion in construction-site world models was ...

The Optics Project (TOP) is a 3D interactive computer graphics system that visualizes optical phenomena. The primary motivation for creating TOP was to develop a tool to help undergraduate students learn optics. WebTOP is a Web-based version of the ...

Business visualization is becoming increasingly important, since managers recognize the power of human visual intuition in information-rich decision tasks. Nevertheless, despite its promises, 3D visualizations are far less common than one would expect.

Motion capture systems usually work in conjunction with complex 3D applications, such as 3D Studio Max by Kinetix or Maya by Alias/Wavefront. Once models have been created in these applications, motion capture systems provide the necessary data input to ...

This paper is a personal reflection on the different communities that are contributing to the design and implementation of multi-user virtual world systems. Given the Web3D Consortium's considered re-labeling from “VRML” to “Web3D” this seems an ideal ...
