<div>Hi</div>
<div> </div>
<div>I am just trying to understand how vtk works.</div>
<div>OOP is really new to me.</div>
<div>By the way I found that I must deal a lot with </div>
<div>VtkIdList class</div>
<div>I do not understand what Id and Ids mean in the general sense.</div>
<div> </div>
<div>Particularly I have no idea what the SetId(id,i) does ??!!</div>
<div>Please help.</div>
<div> </div>
<div>Yours</div>
