Warning: In .\vtkTransform.cxx, line 200
vtkTransform (035E3260): InternalUpdate: doing hack to support legacy code. This is deprecated in VTK 4.2. May be removed in a future version.
Attached against is a patch vtkInteractorStyleTrackballActor which gets rid of the warning. Similar changes need to be made to vtkInteractorStyleJoystickActor
The problem arises because vtkTransform doesn't like anyone meddling with its vtkMatrix4x4... which vtkInteractorStyle*Actor does. The proposed changes, alters the actor's orientation through the UserTransform rather than a new instance of vtkTransform.
Some tcl code to illustrate the bug:
package require vtk
package require vtkinteraction
# create a sphere source, mapper, and actor
#
vtkSphereSource sphere
vtkPolyDataMapper sphereMapper
sphereMapper SetInput [sphere GetOutput]
sphereMapper GlobalImmediateModeRenderingOn
vtkTransform t
vtkLODActor sphereActor
sphereActor SetMapper sphereMapper
sphereActor SetUserTransform t
# Create the Renderer, RenderWindow, and RenderWindowInteractor
#
vtkInteractorStyleTrackballActor style
vtkRenderer ren1
vtkRenderWindow renWin
renWin AddRenderer ren1
vtkRenderWindowInteractor iren
iren SetRenderWindow renWin
iren SetInteractorStyle style
# Add the actors to the renderer, set the background and size
#
ren1 AddActor sphereActor
ren1 SetBackground 1 1 1
renWin SetSize 300 300
# Set the user method (bound to key 'u')
iren AddObserver UserEvent {wm deiconify .vtkInteract}
iren Initialize
# Withdraw the default tk window
wm withdraw .
