[vtkusers] vtkimageplanewidget and vtkactor in huge datasets - part 2

[Oliver Weinheimer]

Hi all,

i tested my application on a win xp system and everything works fine - so
it's maybe a problem with win nt?

Hi all,

i'm woking with the vtkimageplanewidget with vtk 4.2.1 and BCB 6.0 and Win
Nt 4.0.
the visualization with vtkimageplanewidget works fine. I'm using the
TvtkBorlandRenderWindow.
I created 3 planes like this one:

planeWidgetZ = vtkImagePlaneWidget::New();

planeWidgetZ->SetInteractor(vtkWindow1->GetRenderWindow()->GetInteractor());
    planeWidgetZ->DisplayTextOn();
    planeWidgetZ->SetLookupTable(bwLut);
    planeWidgetZ->SetInput(importer->GetOutput());
    planeWidgetZ->SetPlaneOrientationToYAxes();
    planeWidgetZ->SetSliceIndex(2);
    planeWidgetZ->GetPlaneProperty()->SetColor(0,1,0);
    planeWidgetZ->SetKeyPressActivationValue('x');
    planeWidgetZ->RestrictPlaneToVolumeOn();
    planeWidgetZ->On();

after this, i added an actor to the the same renderer

  vtkRenderer *aRenderer = vtkWindow1->GetRenderer();
  aRenderer->AddActor(actor1);

everything works fine in a dataset of 512x512x12 voxels - but the mouse
interaction (left mouse button and middle mouse button)
crashs my application if i do the same things in a huge dataset (512x512x129
voxel) ...

Could somebody help me? Any ideas?

regards
oliwe
