Interactive 3D Multimedia Content

Introduction to Interactive 3D Multimedia Content

Abstract Progress in computing and network performance, accompanied by development of platform independent 3D content standards, opens the way for application of interactive 3D technologies in a variety of domains such as cultural heritage, education, training, tourism, and e-commerce. However, the potential of 3D/VR/AR technologies in everyday applications can be fully exploited only if complemented […]

Content Representation Standards (Interactive 3D Content Standards) Part 1

Abstract Development of 3D interactive network applications requires standards for representing 3D content as well as metadata standards for describing the content. In this chapter, selected standards for content representation and content description are presented. In particular, the VRML, X3D, and MPEG-4 ISO/IEC standards are presented. Other standards such as U3D, COLLADA, and 3D XML […]

Content Representation Standards (Interactive 3D Content Standards) Part 2

Representation of Media Objects MPEG-4 standardizes a number of primitive types of media objects, which can represent both natural and synthetic content types. These media objects can be either two- or three-dimensional. Primitive media objects types include: List. 2.2 Code of the VRML scene from List. 2.1 encoded in X3D format   •    still images, […]

Content Representation Standards (Interactive 3D Content Standards) Part 3

COLLADA COLLADA (Collaborative Design Activity) is an intermediate format designed for content interchange between 3D authoring applications. The work on COLLADA has been started in 2003 by Sony Computer Entertainment supported by a growing group of other companies. In 2005, Khronos Group [54] accepted COLLADA as industry standard [13]. Similarly as X3D, COLLADA is a […]

Metadata for Describing Multimedia Content (Interactive 3D Content Standards)

Metadata can be used to describe contents and characteristics of data resources. Metadata descriptions permit to more efficiently organize, search, access, and interpret content, and therefore are critical to facilitate content reuse. Different types of metadata may be used for different types of content and for different application areas. Numerous metadata standards have been developed […]

From Passive 3D Content to Active 3D Applications (Issues in Creation, Management, Search and Presentation of Interactive 3D Content)

Abstract In this topic, the main issues and challenges related to creation, management, search and presentation of interactive 3D content are presented. The challenges result mainly from the continuous progress in development of 3D/VR technologies and systems. In particular, the following shifts are presented: from passive 3D content to active 3D applications, from 3D geometry […]

From 3D Geometry to Meaningful Interactive Virtual Environments (Issues in Creation, Management, Search and Presentation of Interactive 3D Content)

Creation of interactive 3D multimedia content is a complex task that requires significant expertise and effort. Since practical 3D applications need large amounts of meaningful high-quality content, the difficulty of content creation becomes one of the main problems limiting wider use of 3D applications on everyday basis. Important is to enable creation of content by […]

From Single-user to Multi-user 3D Content Creation (Issues in Creation, Management, Search and Presentation of Interactive 3D Content)

In many application areas, such as entertainment, social networking or education, there are clear advantages of employing multi-user collaborative virtual environments. Such environments enable users to navigate in a shared virtual space and interact with virtual objects and avatars representing other users [1, 15, 59, 61, 64, 74]. Beyond the advantages of communicating with other […]

From File Search to 3D Object Search (Issues in Creation, Management, Search and Presentation of Interactive 3D Content)

Undeniable success of the Word-Wide Web is to a large extent a result of the availability of efficient search systems which enable users to find relevant information and resources within seconds. Search systems are also critical to facilitate reuse of content and software on a large scale. However, due to different nature of the 3D […]
