Hi there,
I’m showing growth of a plant as a point cloud and I’d like to provide a full circular camera orbit pass for each recording of the plant. This is different than what I’ve created already which is a single orbit for multiple plant point clouds (different time steps) [rotating.avi - Google Drive](https://drive.google.com/file/d/13UWOxt-QzQqoHxYHWm0no11Il2vGlON4/view?usp=sharing).
I believe this is similar to this question [Multiple camera orbits in Paraview - Stack Overflow](https://stackoverflow.com/questions/52700873/multiple-camera-orbits-in-paraview), but it doesn’t have an answer. I found another post here that recommends manually constructing the orbit paths, but that seems pretty arduous for as many timesteps as I have per plant, and the fact I have a large quantity of plants total ( [Rotation of the camera at a specific speed - #5 by bastiend](https://discourse.paraview.org/t/rotation-of-the-camera-at-a-specific-speed/2841/5) ).
I noticed that I could create another `CameraKeyFrame` and append it to the existing camera, and then I tried to copy the `PositionPathPoints` and other attributes from the previous camera orbit keyframe to the new one. This seems like it would be a good approach to programmatically adding multiple rotations, but when I add the new Keyframe to the camera track it seems like the `KeyTime` starts updating in weird unintuitive ways.
Here’s a video showing the things I’ve tried and hopefully it is simple enough to recreate. [Screencast from 02-10-2023 08:12:38 AM.webm - Google Drive](https://drive.google.com/file/d/19rhdRgWxF4jRVXvxDKwDk2_dTmdmlrDc/view?usp=sharing)
Any suggestions for how to approach this differently?

Hi @Devin_Richard_Bayly
What is the question here ? I’m not sure to follow what is not working as you expect or what you are not able to achieve.
Best,

Sorry to be unclear, I also just noticed the video doesn’t seem to be working as a way to showcase the problem. I’ll make sure to update this post by the end of the day.

Well, I’m not sure about the bug I was encountering but I just had some luck with this script. Perhaps we can close the books on this and I’ll suggest my script on the stack overflow link mentioned above.
```auto
from paraview.simple import *
anim = GetAnimationScene()
renderView1 = GetActiveViewOrCreate("RenderView")
cameraAnimationCue1 = CameraAnimationCue()
#cameraAnimationCue1 = GetCameraTrack(view=rv)
cameraAnimationCue1.Mode = 'Path-based'
cameraAnimationCue1.AnimatedProxy = renderView1
# create a new key frame
n = 3
for i in range(n):
keyFrameN = CameraKeyFrame()
keyFrameN.Position = [-6.6921304299024635, 0.0, 0.0]
keyFrameN.FocalPoint = [1e-20, 0.0, 0.0]
keyFrameN.ViewUp = [0.0, 0.0, 1.0]
keyFrameN.ParallelScale = 1.7320508075688772
keyFrameN.PositionPathPoints = [0.0, -5.0, 0.0, 2.938926261462365, -4.045084971874736, 0.0, 4.755282581475766, -1.545084971874737, 0.0, 4.755282581475766, 1.5450849718747361, 0.0, 2.938926261462365, 4.045084971874735, 0.0, 1.3322676295501878e-15, 4.9999999999999964, 0.0, -2.9389262614623624, 4.045084971874735, 0.0, -4.755282581475763, 1.5450849718747368, 0.0, -4.755282581475763, -1.5450849718747341, 0.0, -2.9389262614623632, -4.045084971874731, 0.0]
keyFrameN.FocalPathPoints = [0.0, 0.0, 0.0]
keyFrameN.ClosedPositionPath = 1
keyFrameN.KeyTime = i/n
cameraAnimationCue1.KeyFrames.append(keyFrameN)
# ending scale
keyFrame9333 = CameraKeyFrame()
keyFrame9333.KeyTime = 1.0
keyFrame9333.Position = [-6.6921304299024635, 0.0, 0.0]
keyFrame9333.FocalPoint = [1e-20, 0.0, 0.0]
keyFrame9333.ViewUp = [0.0, 0.0, 1.0]
keyFrame9333.ParallelScale = 1.7320508075688772
# initialize the animation track
cameraAnimationCue1.KeyFrames.append( keyFrame9333)
anim.Cues.append(cameraAnimationCue1)
```
Put simply I was running into an issue with the keytimes getting overwritten, but I can’t recreate that anymore.
