Hi, David<br><br>Here is a short demo code. It is built in an empty console application in Windows 7 with Visual Studio 2008(C++)<br><br>//----------------------------------------------------<br>#include <vtkPolyData.h><br>
#include <vtkPoints.h><br>#include <vtkCellArray.h><br>#include <vtkGenericDataObjectReader.h><br><br>vtkPolyData* polydata = vtkPolyData::New(); // error pops<br>vtkPoints* points = vtkPoints::New(); // no error<br>
vtkCellArray* polygon = vtkCellArray::New(); // no error<br>vtkGenericDataObjectReader* reader = vtkGenericDataObjectReader::New();<br><br>void main()<br>{<br> reader->SetFileName("C:\\Users\\Wenlong\\Desktop\\surface.vtk");<br>
reader->OpenVTKFile();<br> reader->Update();<br><br> polydata = reader->GetPolyDataOutput();<br> points = polydata->GetPoints();<br> polygon = polydata->GetPolys();<br>}<br><br>Many thanks.<br>
