Get the refresh rate to run Vizard in

[Jeff]

I'll have to ask a developer if there is a way to get the refresh rate from a connected HMD. You could check to see if the HMD is connected and hardcode the rate based on that.

The following shows how to create create an action from a node3d command:

import viz
import vizact
viz.go()

viz.MainView.getHeadLight().disable()
viz.clearcolor(viz.SLATE)
ball = viz.addChild('basketball.osgb',pos=[0,1.8,3])

light = viz.addLight()
light.intensity(0)

mix = vizact.mix(0.0, 1.0, time=1.0)
change_intensity = vizact.method.intensity(mix)
light.addAction(change_intensity)
