5 Build Virtual Reality Worlds

General 3-D editing tools target specific types of work. For example, they can target
visual art, animation, games, or technical applications. They offer different working
environments depending on the application area for which they are designed. Some of
these general 3-D editing tools are very powerful, expensive, and complex to learn, but
others are relatively inexpensive and might satisfy your specific needs.
The graphical user interfaces for many of the commercial general 3-D editors use
features typical of the native VRML editing tools. For example, in addition to displaying
3-D scenes in various graphical ways, they also offer hierarchical tree styles that provide
an overview of the model structure and a shortcut to node definitions.
Native VRML Editors
Native VRML editors use VRML as their native format. All the features in the editor are
compatible with VRML. Also, native VRML editors support features that are unique to
the VRML format, such as interpolators and sensors.
The Simulink 3D Animation software includes two native VRML editors:
• “3D World Editor”, which works on all platforms supported for Simulink 3D
Animation product
• The “Ligos V-Realm Builder”, which works on Windows platforms only
3D World Editor
The 3D World Editor is installed as part of the Simulink 3D Animation installation. It is
the default VRML editor.
The 3D World Editor is a native VRML authoring tool that provides an interface to
the VRML syntax. The editor supports all VRML97 types and language elements. Its
primary file format is VRML97.
The 3D World Editor interface provides three panes.
