[vtkusers] VRML & volume rendering

[Costin Alin CACIU]

I have the same problem as Vikram Chalana:

<vtkVRMLExporter (0x009DD8E0): no actors found for writing VRML file.>

My code is:

vtkVRMLExporter *vrml = vtkVRMLExporter::New();
vrml->SetRenderWindow(renWin);
vrml->SetInput(renWin);
vrml->SetFileName(fvrml);
vrml->SetSpeed(5.5);
vrml->Write();

renWin is a window where I render a vtkVolume - vtkVolumeRayCastMapper -
vtkImageData

Thanks,
