draw outline on objects?

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:

Code:

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() )
