33 Virtual Reality Toolbox 2.0 Release Notes
33-2
Introduction to the Virtual Reality Toolbox
The Virtual Reality Toolbox extends the capabilities of MATLAB and Simulink
into the world of virtual reality graphics. Using standard Virtual Reality
Modeling Language (VRML) technology, you can create animated
three-dimensional scenes that are driven from the MATLAB and Simulink
environment.
Simulink Interface
You can observe a simulation of your dynamic system over time in a visually
realistic three-dimensional model.
Most of the Virtual Reality Toolbox features can be implemented with
Simulink blocks. Once you include these blocks in a Simulink diagram, they
allow you to select the virtual world, which you connect to Simulink signals.
The Virtual Reality Toolbox automatically scans the virtual world for available
VRML nodes that can be driven by Simulink.
MATLAB Interface
The Virtual Reality Toolbox provides a flexible MATLAB interface to a virtual
reality world.
Virtual Reality Modeling Language (VRML)
The Virtual Reality Modeling Language (VRML) is an ISO standard that is
open, text-based, and uses a WWW-oriented format. You use VRML to define a
virtual world that you can display in a Web browser and connect to a Simulink
model.
The Virtual Reality Toolbox uses many of the advanced features defined in the
current VRML97 specification. The term VRML, in this chapter, always refers
to VRML as defined in the VRML97 standard ISO/IEC 14772-1:1997. This
format includes a description of three-dimensional scenes, sound, internal
actions, and WWW anchors.
