How to make my scenes follow my ball?

[saravanan.balak]

I want my scenes to change when the ball moves from one position to another.

import viz
import vizinfo
import vizdlg
import vizinput
import time
import viztask
import vizact
data = viz.Data()

#viz.mouse(viz.OFF)
viz.go()
light1 = viz.addLight()
light1.setPosition(12.5,0,4)
light1.setEuler(0,20,0)
main=viz.MainView.setPosition(0,0,0)
env = viz.addChild('I:\Vi\File20171.dae')

env.setPosition(12.5,-1,3)
pos = env.getPosition()
orientation = env.setEuler(0,0,0)

ball = viz.addChild('volleyball.osgb')
ball.setScale([0.5,0.5,0.5])
path = viz.addAnimationPath()

points = [ [12.5,-1,3],[-13.999999237060547, 1.399999976158142, 13.5],[-35.59999923706055, 2.399999976158142, 12.5], [-47.979998779296875, 1.2999999523162842, 16.0], [-38.29999923706055, 1.399999976158142, 16.0], [12.5,-1,3] ]

for x,pos in enumerate(points):
path.addControlPoint(0.5*x,pos=pos)

path.setLoopMode(viz.LOOP)

path.play()


link = viz.link(path,ball)
link2 = viz.link(link1,env)

Pls find the below code and use it to integrate with your program code.

import vizcam
camera = vizcam.PivotNavigate()
camera.setDistance(5)

def moveCamera():
	while True:
               # Get the handle of the 3D Model as taken below
		lookAtPos = avatar.getBone('Bip01 Pelvis').getPosition(viz.ABS_GLOBAL)
		lookAtPos[1] = lookAtPos[1] + .5
		camera.setCenter(lookAtPos)
		camera.updateCenter()
		yield None	

viztask.schedule(moveCamera())

Thanx & Regards
