[vtk-developers] vtkActor - BackfaceProperty

[Goodwin Lawlor]

Damn - I thought this catch would fix a bug I've been seeing recently 
(but it doesn't)... turning on the backface culling property of a 
vtkVectorText object disables the rendering of /other/ vtkCaptionActor2D 
actors in the scene. (eg). With
[anteActor GetProperty] BackfaceCullingOff
the "xLabel" reappears. Any ideas?

Thanks,
Goodwin

package require vtk
wm withdraw .


vtkCaptionActor2D xLabel
    xLabel SetCaption X
    xLabel SetAttachmentPoint 0 0 0
    xLabel LeaderOff
    xLabel BorderOff
    xLabel SetPosition 0 0
    [xLabel GetCaptionTextProperty] ShadowOff

vtkVectorText anteText
    anteText SetText "A"
vtkPolyDataMapper anteMapper
    anteMapper SetInput [anteText GetOutput]
vtkActor anteActor
    anteActor SetMapper anteMapper
    [anteActor GetProperty] SetColor 1 1 1
    [anteActor GetProperty] BackfaceCullingOn   
   
vtkRenderer ren
    ren AddActor anteActor
    ren AddActor xLabel

vtkRenderWindow renWin
    renWin AddRenderer ren
vtkRenderWindowInteractor iren
    iren SetRenderWindow renWin
    iren Initialize
