probleme d affchage

Hi, i am working on a project with C++ and VTK and i really need your help!! I have 2 problems: I have a file(.obj) that contains my mesh (the set of facets ans vetices) and i want ton charge it in a data structure ( i think that vtkPolydata is the most suitable. how we can extract ths vertices and facets from the OBJ to the polydata. I have already seen the solution with class vtkOBJreader but i have this error: main.obj : error LNK2001: unresolved external symbol "__declspec(dllimport) public: static class vtkOBJReader * __cdecl vtkOBJReader::New(void)" (__imp_?New@vtkOBJReader@@SAPAV1@XZ) i think that i have a file (OBJreader.dll) missed can you send me this file please (it is in SYSTEM32 folder) please help me!!!!!!

The compiler doesn't check whether the dll is present or not.
However you probably haven't linked to the library file.
You should add somewhere in a code file :
#pragma comment (lib,"vtk.lib")
or whatsoever the lib's name is : refer to vtk's doc which should mention the appropriate lib to link.

ok thanks a lot i will try
