Hi<div><br></div><div>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.</div><div><br></div><div>How can I display the 3D cube created.</div>
<div><br></div><div><br></div><div>Here is the code that I`m using</div><div><br></div><div><div>vtkSmartPointer<vtkImageData> volume = vtkSmartPointer<vtkImageData>::New();</div><div><br></div><div>volume->SetNumberOfScalarComponents(3);</div>
