draw outline on objects?

[Vaquero]

Hey! I saw that there's a highlighter tool, but it depends on the user picking items by sending a ray cast. I'd like to highlight objects that get chosen by my script (randomly from a list of items), not by the user.
Is there a way using the highlighter tool or do I have to create a shader effect?

Yes, the highlighter module has an outline object that you can add models to directly:

import viz
import viztask

viz.setOption('viz.display.stencil',1)
viz.go()

environment = viz.addChild('sky_day.osgb')
soccerball = viz.addChild('soccerball.osgb',pos=[-0.5,1.8,2])
basketball = viz.addChild('basketball.osgb',pos=[0,1.8,2])
volleyball = viz.addChild('volleyball.osgb',pos=[0.5,1.8,2])
items = [soccerball,basketball,volleyball]

from tools import highlighter
outline = highlighter.Outline()

def outlineTask():
	
	while True:
		
		for item in items:
			outline.add(item)
			yield viztask.waitKeyDown(' ')
			outline.remove(item)
			
viztask.schedule( outlineTask() )
