[vtk-developers] How to recalculate a matrix of parts of vtkAssembly?

[Kacper Pluta]

I prepared a program(You can compile it right away.) that demonstrates my
problem. Main part looks like.


/*********Start of code describing the problem.***************************/
  //Send to the output the actual coordinates of last Item in vtkAssembly
  std::cout << "X min " <<  *root->GetLastProp3D()->GetXRange() << " X max "
<< *(root->GetLastProp3D()->GetXRange()+1) << " Y min " <<
*(root->GetLastProp3D()->GetYRange()) << " Y max " <<
*(root->GetLastProp3D()->GetYRange()+1) << std::endl;

  double *orientation = root->GetLastProp3D()->GetOrientation();

  //Send to the output the actual orientation of last Item in vtkAssembly
  std::cout << "Orientation " << *orientation << " " << *(orientation+1) <<
" " <<  *(orientation+2) << std::endl;

  //Change orientation of whole vtkAssembly structure
  Tree->SetOrientation(90,35,45);
  Tree->SetPosition(0,2,1);
  orientation = root->GetLastProp3D()->GetOrientation();

  //Send to the output the new coordinates of last Item in vtkAssembly
  std::cout << "X min " <<  *root->GetLastProp3D()->GetXRange() << " X max "
<< *(root->GetLastProp3D()->GetXRange()+1) << " Y min " <<
*(root->GetLastProp3D()->GetYRange()) << " Y max " <<
*(root->GetLastProp3D()->GetYRange()+1) << std::endl;
  //Send to the output  the new orientation of last Item in vtkAssembly
  std::cout << "Orientation " << *orientation << " " << *(orientation+1) <<
" " <<  *(orientation+2) << std::endl;
  //Why nothing has changed?

 /*********End of code describing the problem.***************************/
