Alright, that was what I was looking for. Now I want to manipulate it from within the program. This is what I have:

import viz
import vizshape

viz.go()

viz.MainView.setPosition(0,0,-4)

slider = viz.addSlider()
slider.setPosition(0.2, 0.1)
slider.set(0.1)

def onSlider():
	x = slider.get()
	print x
	myshape = vizshape.addCylinder(height=1.0,bottomRadius=0.5,topRadius=x)

vizact.onupdate(0, onSlider)

But when I move the slider the top of the cone only gets bigger, not smaller. What am I doing wrong?
