[Visualpython-users] rotation of camera

[alessandro <bom...@gm...>]

I want to rotate 90° around the center objects  with an animation. I 
tried this:


from visual import *
ball = sphere(pos=(-5,0,0), radius=0.5, color=color.red)
wallR = box(pos=(6,0,0), size=(0.2,4,4), color=color.green)
alfa=0
while alfa < radians(90):
    rate(20)
  
    scene.forward = scene.forward.rotate(angle=alfa, axis=(0,1,0))
   
    alfa += radians(1)

both the sphere & box rotate but they rotate for not only for 90° but 
serveral time. Where is the error?
