[Paraview] Specifying camera movement using points from a file

[Biddiscombe, John A.]

There is a very old branch here

https://github.com/biddisco/ParaView/commits/jb-4.0-volrender


with two commits that add a helix generator to the pv gui.

No idea if they would still merge with master - they date back to 2013, but if someone wanted an interactive helix edit for camera path ....

Hi Cory,

Thanks for your feedback.

Of course this can be handled with a Python script - sometimes the answer is so obvious ;-)

I will follow your advice and let you know if I encounter any problems.

Regards,
Per

Per,

You can do this with Python scripting in the Python console.

# get active view
renderView1 = GetActiveViewOrCreate('RenderView')

# uncomment following to set a specific view size # renderView1.ViewSize = [689, 340]

# get camera animation track for the view
cameraAnimationCue1 = GetCameraTrack(view=renderView1)

# create keyframes for this animation track # create a key frame
keyFrame4737 = CameraKeyFrame()
keyFrame4737.Position = [0.0, 0.0, 6.69] keyFrame4737.ParallelScale = 1.73

keyFrame4737.PositionPathPoints = [0.0, 0.0, 5.0, 2.938926261462365, 0.0, 4.045084971874736, 4.755282581475766, 0.0, 1.545084971874737, 4.755282581475766, 0.0, -1.5450849718747361, 2.938926261462365, 0.0, -4.045084971874735, 1.3322676295501878e-15, 0.0, -4.9999999999999964, -2.9389262614623624, 0.0, -4.045084971874735, -4.755282581475763, 0.0, -1.5450849718747368, -4.755282581475763, 0.0, 1.5450849718747341, -2.9389262614623632, 0.0, 4.045084971874731]

keyFrame4737.FocalPathPoints = [0.0, 0.0, 0.0] keyFrame4737.ClosedPositionPath = 1

# create a key frame
keyFrame4738 = CameraKeyFrame()
keyFrame4738.KeyTime = 1.0
keyFrame4738.Position = [0.0, 0.0, 6.69] keyFrame4738.ParallelScale = 1.73

# initialize the animation track
cameraAnimationCue1.Mode = 'Path-based'
cameraAnimationCue1.KeyFrames = [keyFrame4737, keyFrame4738]

# get animation scene
animationScene1 = GetAnimationScene()

animationScene1.Play()

Just modify the keyFrame4737.PositionPathPoints. They are ordered [x, y, z, x, y, z ...].

HTH,
Cory
