[vtkusers] displaying .raw data

[tony hakki]

here is my code. When I run it without vtkPolyDataMapper ,a black window appears and an error appear on an another window like that"ERROR: In ..\..\vtk-src-windows\Rendering\vtkImageActor.cxx, line 182
vtkOpenGLImageActor (01654BB0): This filter requires unsigned char scalars as input". When I use vtkPolyDataMapper It gives an converting parameter error. like that"
vtkPolyDataMapper::SetInput' : cannot convert parameter 1 from 'vtkImageData *' to 'vtkPolyData *'


vtkImageReader *read=vtkImageReader::New();
read->SetFileName( "3Ddata.raw");

vtkPolyDataMapper *readmap2=vtkPolyDataMapper::New();
readmap2->SetInput(read->GetOutput());

vtkImageActor *lodactor=vtkImageActor::New();
lodactor->SetInput(read->GetOutput());
lodactor->InterpolateOff();

vtkRenderer *ren1=vtkRenderer::New();
vtkRenderWindow *renwin=vtkRenderWindow::New();
renwin->AddRenderer(ren1); 
vtkRenderWindowInteractor *iren=vtkRenderWindowInteractor::New();

iren->SetRenderWindow(renwin);
ren1->AddActor(lodactor);
ren1->SetBackground(0,0,0);

renwin->SetSize(500,500); 
ren1->ResetCamera();
ren1->GetActiveCamera()->Zoom(1.5);
renwin->Render();
iren->Start();
