The software analyzes the structure of the virtual world, determines what signals are
available, and makes them available from the MATLAB and Simulink environment.
Simulink 3D Animation software ensures that the changes made to a virtual world are
reflected in the MATLAB and Simulink interfaces. If you change the viewpoint in your
virtual world, this change occurs in the vrworld object properties in MATLAB and
Simulink interfaces.
The software includes functions for retrieving and changing virtual world properties.
Note: Since some VRML worlds are automatically generated in VRML1.0, and the
Simulink 3D Animation product does not support VRML1.0, you need to save these
worlds in the current standard for VRML, VRML97.
For PC platforms, you can convert VRML1.0 worlds to VRML97 worlds by opening the
worlds in Ligos V-Realm Builder and saving them. V-Realm Builder is shipped with the
PC version of the software. Other commercially available software programs can also
perform the VRML1.0 to VRML97 conversion.
VRML Compatibility
The Simulink 3D Animation product currently supports most features of VRML97, with
the following limitations:
• The Simulink 3D Animation server ignores the VRML Script node, but it passes the
node to the VRML Viewer. This allows you to run VRML scripts on the viewer side.
You cannot run them on the Simulink 3D Animation server.
• In keeping with the VRML97 specification, the Simulink 3D Animation Viewer
ignores BMP files. As a result, VRML scene textures might not display properly in the
Simulink 3D Animation Viewer. To properly display scene textures, replace all BMP
texture files in a VRML scene with PNG, JPG, or GIF equivalents.
For a complete list of VRML97 nodes, refer to the VRML97 specification.
