3D World Editor Library
6-25
• The first Transform node of the file that you select from another location is inserted
in place into the tree view of the virtual world that you are editing.
• If you want to insert a whole VRML file into the virtual world that you are editing,
use the Nodes > Inline VRML file menu option.
Before you add a custom library object from a location other than from the 3D World
Editor object library, see “Guidelines for Using Custom Objects”.
Guidelines for Using Custom Objects
If you use a VRML object from a source other than from the 3D World Editor object
library, the object must comply with the following guidelines:
• A component object must be in a VRML file that contains at least one Transform
node.
• A material object must be a VRML file whose only content is a fully-qualified
Material node.
• A texture object must be in either:
• A .png, .jpg, or .gif graphics file for use in the URL field of an ImageTexture
node.
• A VRML file whose only content is a fully qualified ImageTexture node.
If you create VRML objects to use with the 3D World Editor, create your own folder for
storing the custom objects. Avoid using the 3D World Editor library folder to ensure that
you can:
• Edit the custom library object in the library folder; the 3D World Editor library
folders are generally read-only.
• Update to a future version of the Simulink 3D Animation product without
compatibility issues relating to mixing custom objects with the 3D World Editor
objects.
