[vtkusers] vtkVolume vtkActor

[Jochen K.]

Hi Antonio,


I'm sorry for that.

Hmm, you say the class extracts a polydata from the actor.


Assuming your volume source is a vtkImageData you could use
vtkImageDataGeometryFilter to convert it to a polyData object. Then you can
use this as the input of a vtkPolyDataMapper and finally create a vtkActor.


//...
vtkSmartPointer<vtkImageDataGeometryFilter> filter =
vtkSmartPointer<vtkImageDataGeometryFilter>::New();
filter->SetInput(yourImageData)
vtkSmartPointer<vtkPolyDataMapper> mapper =
vtkSmartPointer<vtkPolyDataMapper>::New();
mapper->SetInputConnection(filter->GetOutputPort());
vtkSmartPointer<vtkActor> actor =
vtkSmartPointer<vtkActor>::New();
vtkActor->SetMapper(mapper);
//...



Maybe this is an workaround for your problem.


best regards
Jochen
