Problem about vtk

[Lisa S. Avila]

Hello Lili,

What do you mean by "attach only one actor to the camera"? If you mean how 
do you move only one actor, then try hitting the "o" key (to put the 
interactor into "object" mode) You should then be able to rotate / 
translate an object that you pick by clicking on it. But maybe you mean 
something else...?

Try looking at vtkImageDifference. This can be used to see how similar two 
image are.
