Introduction
0.1 Overview
Extensible 3D (X3D) is a software standard that defines Web-based and broadcast-based 3D content that integrates multimedia. X3D
Can be used for a variety of hardware devices and a variety of applications such as engineering and scientific visualization, multimedia presentation, entertainment and education, web and shared virtual
world. X3D also tries to become a unified format for integrated 3D graphics and multimedia. X3D is Virtual Reality Modeling Language (VRML)
Successor, VRML is the original Web-based 3D graphics (ISO /IEC 14772). X3D is an improvement on VRML, with new ones
Features, advanced application programming interfaces, new data encoding formats, more stringent compliance and the ability to support standard components in a modular manner
Of the architecture.
This introduction is an introduction to the background, including the design goals behind X3D development, the X3D feature review, and the description of the X3D specification process.
0.2 design goals
X3D is to meet specific market and technical needs to develop, to meet these needs, X3D uses the following design goals.
● separating the runtime architecture from the data encoding;
● Supports multiple encoding formats, including Extensible Markup Language (XML);
● Added new graphics, behavior and interaction objects;
● Provide multiple optional application programming interfaces (APIs) to the 3D scene;
• Define a specification subset ("configuration file") that meets different market requirements;
● allow the implementation of specifications at different service levels;
• Eliminate unspecified or implicitly regulated behavior as much as possible.
0.3 X3D features
X3D has a rich set of features to support such as engineering and scientific visualization, multimedia presentation, entertainment and educational programs, web pages and
Share the virtual world. The X3D feature set includes.
● 3D graphics. multi-faceted geometry, parametric geometry, hierarchical transformation, illumination, material and multi-step or multi-stage texture mapping;
● 2D graphics. text, two-bit vector and plane shape displayed in the 3D transformation hierarchy;
● animation. drive continuous animation timer and interpolator; human animation and deformation;
● spatial audio and video. mapping to the scene in the geometry of the audio and video source;
● user interaction. mouse-based click and drag; keyboard input;
● navigation. camera; user movement in 3D scene; collision detection, proximity detection and visibility detection;
● User-defined objects. Expand the built-in functionality of the browser by creating user-defined data types;
● Script. dynamically changes the scene through the programming language and scripting language;
● Networking. assembling an X3D scene with resources on the network; hyperlinking objects to other scenes in the World Wide Web
On the source
● Physical simulation. human animation; geospatial datasets; integration with distributed interactive simulation protocols (DIS).
For a complete list of X3D features, see Chapter 7 through Chapter 29 for a description of the components.

Part 1. architecture and infrastructure components
1 Scope
GB/T 28170 defines a software system that integrates 3D graphics and multimedia capabilities with network capabilities. Conceptually, every X3D
The application is a time-base three-dimensional space, which consists of graphics and auditory objects that can be dynamically modified by a variety of mechanisms. This section defines X3D
The architecture and the underlying components.
X3D semantics describes a time-based, three-dimensional interactive, multimedia information abstract function behavior. This section does not define physical settings
Or any other implementation-related concepts (such as screen resolution and input devices). This part is intended to be used as widely as possible
Preparation and application, in the interpretation and implementation of the function as far as possible to provide a wide range. For example, this section does not assume a mouse or a two-dimensional display device
Must exist.
X3D applies to.
a) implicitly create a world coordinate space for all defined objects and all the objects contained in the application;
b) Explicitly define and combine 3D objects and multimedia objects;
c) can be specified with other files or applications hyperlinks;
d) Define program-driven or data-driven object behavior;
e) can be connected to an external module or application via a programming language or scripting language;
f) Declaring a functional requirement by defining a configuration file;
g) Additional functional requirements can be declared by defining components.
