Looking for a shape

For a model I'm working on I need a shape that looks like a cone with its tip cut off. I want to be able to control the diameter of both sides. Is there a way to achieve this in Vizard?

Code:

import vizshape

myshape = vizshape.addCylinder(height=1.0,bottomRadius=0.5,topRadius=0.1)

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

Code:

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?

You'll need to remove the cylinder you already added to see the new clinder you add with a smaller radius:

Code:

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)



myshape = vizshape.addCylinder(height=1.0,bottomRadius=0.5,topRadius=0.1)



def changeRadius(pos):

        global myshape

        myshape.remove()

        myshape = vizshape.addCylinder(height=1.0,bottomRadius=0.5,topRadius=slider.get())



vizact.onslider(slider, changeRadius)

Thanks, that works well. I was just wondering if there was an easier way to do that--i.e., instead of erasing cones and rendering new ones, could I call, say, the topRadius with a command and change it?
