X3D (Extensible 3D) is a standard description language for describing 3D scenes on the web environment and can be used to establish 3DVR e-commerce systems, such as virtual shopping malls. However, due to the CPU and memory limitations of mobile devices, the 3DVR e-commerce systems described by using X3D scene language cannot be used on mobile devices. This limitation delays the growth of 3DVR ...

The current Extensible 3D (X3D) specification [5] defines a set of nodes, which are grouped in components and profiles. The extension mechanism of X3D allows only the spontaneous creation of new second-class nodes by prototype statements. We think that it is useful to create new first-class nodes on demand, which might be organized into proprietary unregistered components or profiles to extend ...

This paper proposes and defines four eXtensible 3-dimensional (X3D) nodes to render real-world characters such as human being and animals in 3D virtual environments, which conform to the X3D standard format for representing and rendering real-world characters in virtual spaces, aiming to make them available as an extension of the X3D core nodes. Several examples are implemented to evaluate the ...

Real-time interactive 3D graphics and virtual environments typically include a variety of multimedia capabilities, including video. The Extensible 3D (X3D) Graphics is an ISO standard produced by the Web3D Consortium that defines 3D scenes using a scene-graph approach. Multiple X3D file formats and language encodings are available, with a primary emphasis on XML for maximum interoperability wit...

Extensible 3D (X3D) graphics is a collection of open-standards that define a system that integrates networkenabled 3D graphics and multimedia. X3D applications are real-time, interactive, animated systems that can run in stand-alone or networked environments. This tutorial will focus on a commonly used subset of the complete functionality that is encoded in XML. X3D has three encodings XML (.x3...

In this demo description we present X3DOM, which is an open source framework and runtime system to support the ongoing discussion in the Web3D and W3C communities how an integration of HTML5 and declarative 3D graphics can look like by including X3D elements as part of the HTML5 DOM tree. The goal here is to have a live X3D scene-graph integrated into the HTML DOM, which allows manipulating the...

This paper describes four candidate X3D extension nodes: Camera, Shot, Movement and OfflineRendering. An X3D lexicon for camera movements is defined so that individuals directing virtual cameras in X3D can directly apply terms that film directors and cinematographers understand. This approach greatly simplifies the technical tasks involved in creating precise camera animations and setting up st...

X3D-UML utilises X3D (eXtensible 3D) to enable standards-based advanced 3D UML visualisations. Using X3D-UML, 3D UML State Machine Diagrams have been evaluated against actual user tasks and data, using the Sequential Evaluation methodology. The results of User Task Analysis, Heuristic Evaluation and Formative Evaluation phases provide clear evidence that the use of UML extended with 3D is a pra...
