Animation Camera Orbit Python

ParaView Support

Hello, How can reproduce the Animation by Camera Orbit of the graphic client in Python?
Thanks

Just use the Python trace in ParaView to generate a trace to use in pvpython.

Hi Mathieu, thanks. The problem is that the trace generate the positions of the camera for an specific case I want a general orbit procedure given camera and positions and rotation center. At the end I am doing this:

def saveAnimationOrbit(render_view, path, resolution, animation):
    num_of_keyframes = animation.frames
    animationScene = simple.GetAnimationScene()
    animationScene.ViewModules = [render_view]
    animationScene.NumberOfFrames = num_of_keyframes

    cameraAnimationCue = simple.GetCameraTrack(view=render_view)

    camera = render_view.GetActiveCamera()

    cue = []
    for i in range(0, num_of_keyframes):
        camera.Azimuth(360.0 / num_of_keyframes)
        keyFrame = simple.CameraKeyFrame()
        keyFrame.KeyTime = i * 1.0 / num_of_keyframes
        keyFrame.Position = camera.GetPosition()
        keyFrame.FocalPoint = camera.GetFocalPoint()
        keyFrame.ViewUp = camera.GetViewUp()
        keyFrame.ViewAngle = camera.GetViewAngle()
        cue.append(keyFrame)

    cameraAnimationCue.KeyFrames = cue
    simple.SaveAnimation(path, render_view, ImageResolution=resolution, FrameWindow=[0, num_of_keyframes - 1],
                         FrameRate=animation.frame_rate)

What do you think?
Thanks

Seems good enough ! Thanks for sharing your script.

Is there a way in the previous script to interpolate frames in order to not render all?

I do not think so.
