[Insight-users] vtkDataSets from 3DS files

[justin goyanko]

Hi,

I'm currently trying to get some vtkDataSets from 3DS files. From some similar posts on the mailing list some suggest on getting the data from the renderer itself.
So far what i've done loading it to the renderer but i'm still not able to get the data via GetMapper(). I'm just wondering if i missed something =P

It compiles ok but the program crashes when executed. Using VC++ Express 2008 on windows xp

Below is a sample code:

vtk3DSImporter *importer = vtk3DSImporter::New();
    importer->ComputeNormalsOn();
    importer->SetFileName("C:/vtk3ds_test/bunny.3DS");
    importer->Read();

    vtkRenderWindow* renWin = (importer->GetRenderWindow());
    vtkRenderWindowInteractor *iren = vtkRenderWindowInteractor::New();
    iren->SetRenderWindow(renWin);

    renWin->SetSize(300, 300);

    vtkRenderer* ren = (importer->GetRenderer());
    ren->SetBackground(0.1, 0.2, 0.4);

    vtkActorCollection *acol = vtkActorCollection::New();
    acol = ren->GetActors();

    vtkActor *actor = vtkActor::New();
    actor = acol->GetLastActor();
    cout << "actor:" << actor->GetClassName() << endl;
    
    vtkOpenGLActor *oglActor = vtkOpenGLActor::New();
    oglActor = (vtkOpenGLActor*)acol->GetLastActor();
    cout << "oglActor: " << oglActor->GetClassName();
    
     oglActor->GetMapper();          (ERROR ON THIS LINE)
