[Paraview] Python: How to change the location and size of orientation axes?

[Liang Wang]

I figured out a way by using the vtkAxesActor class directly.

An example script:

from paraview.simple import *
paraview.simple._DisableFirstRenderCameraReset()

renderView1 = GetActiveViewOrCreate('RenderView')

sphere1 = Sphere()
sphere1.Radius = 1.0
sphere1Display = Show(sphere1, renderView1)
sphere1Display.SetRepresentationType('Outline')

import vtk
renderer = renderView1.GetRenderer()
axes = vtk.vtkAxesActor()

#axes.SetAxisLabels(0) # 0/1 to turn off/on axis labels

transform = vtk.vtkTransform()
transform.Translate(-1.0, -1.0, -1.0)
transform.Scale(0.75, 0.75, 0.75)
axes.SetUserTransform(transform)

tprop = vtk.vtkTextProperty()
#tprop.SetFontSize(6) # seems to be overriden by vtkCaptionActor2D
tprop.SetBold(1)
tprop.SetItalic(0)
tprop.SetColor(1.0, 1.0, 1.0)
tprop.SetOpacity(1.0)
tprop.SetFontFamilyToTimes()

for label in [
        axes.GetXAxisCaptionActor2D(),
        axes.GetYAxisCaptionActor2D(),
        axes.GetZAxisCaptionActor2D(),
        ]:
    # set Positoin2
    label.SetWidth(label.GetWidth() * 0.5)
    label.SetHeight(label.GetHeight() * 0.5)
    label.SetCaptionTextProperty(tprop)

renderer.AddActor(axes)

Interact()
