<div>hi all,</div>
<div>I am reading 2D BMP slices to build a 3D volume and rendering it using vtk.</div>
<div>I am using KWWidgets to build a UI for my application.</div>
<div>For this purpose I need to change opacity the 3D volume in real time (interactively)</div>
<div>Can someone suggest possible ways that I can do this?</div>
<div>Does the vtkKWPiecewiseFunction have to be used along with a check button for this purpose ?</div>
<div>Thanks!</div>
