<html><div style='background-color:'><P>Hi every one,</P>
<P>I am using vtk3.2 with VtkkQt to provide GUI. I first load from the program a stack of pgm files using vtkPNMReader, which is okay. Then from the GUI, i pass the angle to rotate the volume, but strangely, it mades another copy of the actor in the scene, and whenever you enter a new angle, the actor keep duplicating. This does not happen if you are using vtkPolyData...</P>
<P>any suggestion.</P>
<P>thanks</P><BR><BR><BR>
