Create new vrworld object associated with virtual world
myworld = vrworld(filename) myworld = vrworld(filename,'reuse') myworld = vrworld(filename, 'new') myworld = vrworld myworld = vrworld('') myworld = vrworld()
String containing the name of the VRML file from which the virtual world is loaded. If no file extension is specified, the file extension .wrl is assumed.
Argument to create a virtual world associated with filename.
myworld = vrworld(filename) creates a virtual world associated with the VRML file filename and returns its handle. If the virtual world already exists, a handle to the existing virtual world is returned. Specify the file name as a string.
myworld = vrworld(filename,'reuse') has the same functionality as myworld = vrworld(filename).
myworld = vrworld('filename', 'new') creates a virtual world associated with the VRML file filename and returns its handle. It always creates a new virtual world object, even if another vrworld object associated with the same VRML file already exists.
myworld = vrworld creates an invalid vrworld handle
myworld = vrworld('') creates an empty vrworld object that is not associated with any VRML file
myworld = vrworld() returns an empty array of returns an empty array of vrworld handles.
A vrworld object identifies a virtual world in a way very similar to a handle. All functions that affect virtual worlds accept a vrworld object as an argument to identify the virtual world.
If the given virtual world already exists in memory, the handle to the existing virtual world is returned. A second virtual world is not loaded into memory. If the virtual world does not exist in memory, it is loaded from the associated VRML file. The newly loaded virtual world is closed and must be opened before you can use it.
The vrworld object associated with a virtual world remains valid until you use either delete or vrclear.
