How to use grabber tool with wand?

[Samuli]

Hi Jeff,
I'd appreciate if you have some knowledge on how to use grabber tool with wand using ppt-tracking and wand 2014? Few more questions: What are proxy tools? What is the proxywrapper/grabberwrapper, their functions and what does the following code snippet from box stacker demo code do?

def init():
	"""Initialize the demo, only called once"""
	# add grabber tools based on proxy tools
	for proxyWrapper in vizconnect.getToolsWithMode('Proxy'):
		grabberTool = tools.grabber.HandGrabber(usingPhysics=True,
												usingSprings=True,
												placementMode=tools.placer.MODE_MID_AIR)
		
		name = 'box_stacker_grabber_tool_based_on_'+proxyWrapper.getName()
		grabberWrapper = vizconnect.addTool(raw=grabberTool,
											name=name,
											make='Virtual',
											model='Grabber')
		# parent the grabber wrapper to the proxy's parent
		grabberWrapper.setParent(proxyWrapper.getParent())

I can't find any relevant information about these things in the Vizard documentation/reference.

You can add a grabber tool and map the wand input signals to the grabber functions in vizconnect. The vizconnect avatars and tools tutorial covers this topic using a desktop setup but the same concepts apply if you're using PPT tracking and wand. The proxy tool is used with the demo launcher as a placeholder tool. This is most likely unnecessary for your application but a description of the proxy tool is shown when you select it in the vizconnect > tools dialog.
