Hello everybody,<br>
My name is Nie. And I am very sorry for such a newbie.<br>
I am now working with a project on iOS. I choose VTK as the
rendering engine. But I have came up eith a problem on reading stl(
or other 3D type file is OK, like vtp).<br>
I first followed th tutorial on
<a class="moz-txt-link-freetext" href="http://www.vtk.org/Wiki/VTK/Examples/Cxx/IO/ReadSTL">http://www.vtk.org/Wiki/VTK/Examples/Cxx/IO/ReadSTL</a><br>
But I get a file not found error (the .stl file is in the app
bundle).<br>
Then I changed the stl to vtp using 3Dslicer and tried to read vtp
referring to readvtp tutorial. This time I get a error opening file
code. <br>
Could anyone give me some hints to solve this?<br>
Thank you.<br>
I am now using VTK6.20 and the version of Xcode is 6.3.1.<br>
Best regards,<br>

read stl code //vtkSTLreader is changed to vtkXMLPolyDataReader when
reading vtp<br>
----------------------------------------------<br>
(void) loadSTL(string name){<br>
vtkNew<vtkSTLReader> reader;<br>
reader->SetFileName("tissue.stl"/*name.c_str()*/);//actually
it is called in another function<br>
reader->Update();<br>
vtkNew<vtkPolyDataMapper> mapper;<br>
mapper->SetInputConnection(reader->GetOutputPort());<br>
mapper->Update();<br>
vtkNew<vtkActor> actor;<br>
actor->SetMapper(mapper.Get());<br>
_myVTKRenderer->AddActor(actor.Get());//_myVTKrenderer is defined
before this <br>
}<br>
