[yt-users] cam.rotate

[John Regan]

Hi All,

Just a quick question on rotation of the camera object. When I rotate the
camera I notice that the
center no longer stays at the focus. I'm running a script which zooms and
rotates an object in a timeseries fashion.

# Code snippet
    cam = pf.h.camera(c, L, W, (N,N), transfer_function=tf,
north_vector=up,
                      no_ghost=True, steady_north=True)
 #Rotate about the "Lperp" vector
    theta = rotation*filenum
    cam.rotate(theta, rot_vector=Lperp)


This pretty much works as I want but after a while a get an output like the
one attached with the central density no longer at the center. Is there a
way to keep the focus at "c".

Cheers,
John
