Animation with Up-Vector / tilt

Is there a way of setting up an animation in rhino 6 including a camera “up-vector”/camera tilt?
Specifically I would like to do this from a C# component in GH.
In the rhinocommon documentation I can see CameraPoints and TargetPoints but some way of setting rotation around the camera axis seems to be missing.

Hi Void,
CameraUp is available: https://developer.rhino3d.com/api/RhinoCommon/html/P_Rhino_Display_RhinoViewport_CameraUp.htm

Jess beat me to it, as I was making a quick camera tumbler as poc:

import rhinoscriptsyntax as rs
import scriptcontext as sc
import Rhino
import math


viewport = sc.doc.Views.ActiveView.ActiveViewport

upvec = viewport.CameraUp

dirvec = viewport.CameraZ

steps = 180
step = 2*math.pi/180

for i in range(steps):
    upvec.Rotate(step, dirvec)
    viewport.CameraUp = upvec
    rs.Redraw()

Thanks guys.

I’m aware of CameraUp in viewport, but what I’m really after is how to set this up with the animation tools.

Ideally it would have the option to set an array of up-vectors as well or a method similar to this:
animation.AddFrame(Point3d camPos, Point3d camTarget, Vector3d camUp)
