Summary0001684: can't add vtkPropAssembly to vtkPropAssembly
DescriptionThe documentation says that a PropAssembly can contain other PropAssemblies, but my code seg faults when I try this.

I create two PropAssemblies, one with a ConeSource and one with a SphereSource, add them to the Renderer, this works.

I create two PropAssemblies, one with a ConeSource AND a SphereSource, and then add this to the second PropAssembly -> run-time error "segmentation fault", app crashes

Short code segment:

#include "vtkConeSource.h"
#include "vtkSphereSource.h"
#include "vtkPolyDataMapper.h"
#include "vtkRenderWindow.h"
#include "vtkRenderWindowInteractor.h"
#include "vtkCamera.h"
#include "vtkPropAssembly.h"
#include "vtkActor.h"
#include "vtkRenderer.h"
 
int main( int argc, char *argv[] )
{
 
vtkRenderer *ren1= vtkRenderer::New();
vtkRenderWindowInteractor *iren = vtkRenderWindowInteractor::New();
vtkRenderWindow *renWin = vtkRenderWindow::New();
renWin->AddRenderer( ren1 );
renWin->SetSize( 300, 300 );
iren->SetRenderWindow( renWin );
 
// make a cone
vtkConeSource *cone = vtkConeSource::New();
vtkPolyDataMapper *coneMapper = vtkPolyDataMapper::New();
coneMapper->SetInput( cone->GetOutput() );
vtkActor *coneActor = vtkActor::New();
coneActor->SetMapper( coneMapper );
 
// make a sphere
vtkSphereSource *sphere = vtkSphereSource::New();
vtkPolyDataMapper *sphereMapper = vtkPolyDataMapper::New();
sphereMapper->SetInput( sphere->GetOutput() );
vtkActor *sphereActor = vtkActor::New();
sphereActor->SetMapper( sphereMapper );
 
// this works:
// ren1->AddProp( coneActor );
// ren1->AddProp( sphereActor );
 
 
// this works:
// vtkPropAssembly *pa1= vtkPropAssembly::New();
// pa1->AddPart(coneActor);
// vtkPropAssembly *pa2= vtkPropAssembly::New();
// pa2->AddPart(sphereActor);
// ren1->AddProp(pa1);
// ren1->AddProp(pa2);
                                                                                               
// this doesnt (seg faults):
vtkPropAssembly *pa1 = vtkPropAssembly::New();
pa1->AddPart(coneActor);
pa1->AddPart(sphereActor);
vtkPropAssembly *pa2 = vtkPropAssembly::New();
pa2->AddPart(pa1);
ren1->AddProp(pa2);
                                                                                               
                                                                                               iren->Start();
                                                                                               }
