I have a simple vtkImageViewer2 code displaying 3D data. I am trying to display correct orientation due to ITK to vtk conversion.<div>but change in any of the variables of vtkCamera like viewUp is not reflected in the image. Have tried to see user list but the code seems to be not working.</div>
<div>Please help in finding whats wrong with the code.<br clear="all"><br></div><div><b>// Create Renderer</b></div><div><div>vtkRenderer *ren1 = vtkRenderer::New();</div><div>vtkRenderWindowInteractor *iren = vtkRenderWindowInteractor::New();</div>
