Hi,

I would like to know how to get coordinates for the boundaries of a markup plane in IJK.

In fiducial point case, my understanding is that we can get the following codes:

world = [0, 0, 0, 0]

fiducialNode.GetNthFiducialWorldCoordinates(index, world)

then something like this

p_Ras = [coord[0], coord[1], coord[2], 1.0]

p_Ijk = RasToIjkMatrix.MultiplyDoublePoint(p_Ras)

but I am wondering how to get the coordinates of plane nodes. I couldn’t find the function for it in the vtkMRMLMarkupsPlaneNode class.

Thank you for your help!
