Detailed Description
Display a 2D image.
vtkImageViewer2 is a convenience class for displaying a 2D image. It packages up the functionality found in vtkRenderWindow, vtkRenderer, vtkImageActor and vtkImageMapToWindowLevelColors into a single easy to use class. This class also creates an image interactor style (vtkInteractorStyleImage) that allows zooming and panning of images, and supports interactive window/level operations on the image. Note that vtkImageViewer2 is simply a wrapper around these classes.
vtkImageViewer2 uses the 3D rendering and texture mapping engine to draw an image on a plane. This allows for rapid rendering, zooming, and panning. The image is placed in the 3D scene at a depth based on the z-coordinate of the particular image slice. Each call to SetZSlice() changes the image data (slice) displayed AND changes the depth of the displayed slice in the 3D scene. This can be controlled by the AutoResetCameraClippingRange ivar.
It is possible to mix images and geometry, using the methods:
viewer->SetInput( myImage ); viewer->GetRenderer()->AddActor( myActor );
This can be used to annotate an image with a PolyData of "edges" or or highlight sections of an image or display a 3D isosurface with a slice from the volume, etc. Any portions of your geometry that are in front of the displayed slice will be visible; any portions of your geometry that are behind the displayed slice will be obscured. A more general framework (with respect to viewing direction) for achieving this effect is provided by the vtkImagePlaneWidget .
