[vtkusers] 3D Image Display

[Fabian Torres]

Hi

I`m trying to create a 3D vtk image and initialized it in black. But when I
display the image on a renderer window I only get a flat 2D black Image.

How can I display the 3D cube created.


Here is the code that I`m using

vtkSmartPointer<vtkImageData> volume = vtkSmartPointer<vtkImageData>::New();

volume->SetNumberOfScalarComponents(3);
volume->SetScalarType(VTK_UNSIGNED_CHAR);
volume->SetOrigin(0,0,0);
volume->SetDimensions(volumeExtent[0]+10,volumeExtent[1]+10,volumeExtent[2]+10);
 for(int i=0; i<volumeExtent[0]+9; i++){
for(int j=0; j<volumeExtent[1]+9; j++){
for(int k=0; k<volumeExtent[2]+9; k++){
unsigned char* pixel = static_cast<unsigned
char*>(volume->GetScalarPointer(i,j,k));
pixel[0] = 1;
pixel[1] = 1;
pixel[2] = 1;
}
}
}


vtkSmartPointer<vtkImageActor> volumeActor =
vtkSmartPointer<vtkImageActor>::New();
volumeActor->SetInput(volume);
volumeActor->SetPosition(volumeOrigin[0]+5,volumeOrigin[1]+5,volumeOrigin[2]+5);

vtkSmartPointer<vtkRenderer> renderer = vtkSmartPointer<vtkRenderer>::New();
renderer->SetBackground(1, 1, 1);
renderer->AddActor(volumeActor);

vtkSmartPointer<vtkRenderWindow> renwin =
vtkSmartPointer<vtkRenderWindow>::New();
renwin->AddRenderer(renderer);

renwin->Render();
