[vtkusers] using vtk3DSImporter with C++

[beth at portugalmail.pt]

Hi,

I'm trying to create a conversor from 3D Studio format to VTK format file.
To start, I picked the sample code in:
 /Examples/IO/Python/flamingo.py  (vtk Examples)
and translated it to C++.

I compiled it, and no errors at all.
The problem is in execution time. I received these 2 errors:
unresolved external symbol "__declspec(dllimport) public: static class 
vtkRenderLargeImage * __cdecl vtkRenderLargeImage::New(void)" (__imp_?
New at vtkRenderLargeImage@@SAPAV1 at XZ)
Conversor.obj : error LNK2001: unresolved external symbol "__declspec
(dllimport) public: static class vtk3DSImporter * __cdecl vtk3DSImporter::New
(void)" (__imp_?New at vtk3DSImporter@@SAPAV1 at XZ)

both classes - vtk3DSImporter and vtkRenderLargeImage can't be found in run 
time.

My CMakeList file looks like this:
------------------------------------
PROJECT (Conversor)

FIND_PACKAGE(VTK REQUIRED)
IF(NOT VTK_USE_RENDERING)
  MESSAGE(FATAL_ERROR "Example ${PROJECT_NAME} requires VTK_USE_RENDERING.")
ENDIF(NOT VTK_USE_RENDERING)
INCLUDE(${VTK_USE_FILE})

ADD_EXECUTABLE(conversor conversor.cxx)
TARGET_LINK_LIBRARIES(conversor vtkRendering)
---------------------------------------

My C++ code looks like this:

-----------------------------------------
#include "vtkRenderer.h"
#include "vtkRenderWindow.h"
#include "vtk3DSImporter.h"
#include "vtkRenderLargeImage.h"
#include "vtkRenderWindowInteractor.h"
#include "vtkPNGWriter.h"
#include "vtkCamera.h"

int main( int argc, char *argv[] )
{
// We'll import some data to start. Since we are using an importer,
// we've got to give it a render window and such. Note that the render
// window size is set fairly small.

	vtkRenderer *ren = vtkRenderer::New();
	ren->SetBackground(0.1, 0.2, 0.4);
	vtkRenderWindow *renWin = vtkRenderWindow::New();
	renWin->AddRenderer(ren);
	renWin->SetSize(125, 125);
	vtkRenderWindowInteractor *iren = vtkRenderWindowInteractor::New();
	iren->SetRenderWindow(renWin);

	vtk3DSImporter *importer = vtk3DSImporter::New();
	importer->SetRenderWindow(renWin);
	importer->SetFileName("$VTK_DATA_ROOT/Data/Viewpoint/iflamigm.3ds");
	importer->ComputeNormalsOn();
	importer->Read();

// We'll set up the view we want.
	ren->GetActiveCamera()->SetPosition(0, 1, 0);
	ren->GetActiveCamera()->SetFocalPoint(0, 0, 0);
	ren->GetActiveCamera()->SetViewUp(0, 0, 1);

// Let the renderer compute a good position and focal point.
	ren->ResetCamera();
	ren->GetActiveCamera()->Dolly(1.4);
	ren->ResetCameraClippingRange();

	vtkRenderLargeImage *renderLarge = vtkRenderLargeImage::New();
	renderLarge->SetInput(ren);
	renderLarge->SetMagnification(4);

// We write out the image which causes the rendering to occur. If you
// watch your screen you might see the pieces being rendered right
// after one another.
	vtkPNGWriter *writer = vtkPNGWriter::New();
	writer->SetInputConnection(renderLarge->GetOutputPort());
	writer->SetFileName("largeImage.png");
	writer->Write();

// interact with data
  	iren->Initialize();

  	renWin->Render();
  	iren->Start();

 // Clean up
  	ren->Delete();
  	renWin->Delete();
  	iren->Delete();
  	renderLarge->Delete();
  	importer->Delete();
  	writer->Delete();

  	return 0;
}
------------------------------------------------------

What should I do?

Thanks for any help...

Best regards,

Elizabeth
