[siyan liu]

Hi,all
   I just start to use vtk, when I try to translate the example vtl code in "example/rendering/vtl/cadpart",
I built my code successfully, but met execute error,when execute to:
   
   ren1->GetActiveCamera()->Zoom(1.5);
   renWin->Render();

   the following debug error appears:
   "unhandled exception in cadpart.exe(vtkcommon.dll):0x0000005:Access violation"

   I am waiting anxiously for the answer, thanks in advance.
