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