<DIV><FONT face=Arial size=2>hi,</FONT></DIV>
<DIV><FONT face=Arial size=2> I am new to using VTK and I have
a quesiton about how to map textures to arbitrary shapes. In my particular
case, I am trying to visualize ultrasound data. In this case, the data
does not posess a rectilinear distribution, but rather it looks more like a pie
wedge. </FONT></DIV>
<DIV><FONT face=Arial size=2> So, if my texture consists
of a 2D array, how would I map it to a wedge shape given I know where each
texture/data point should map to in physical 2-D space? I have taken a
look at the vtkDataSetMapper, and I believe that this is the right way to
procede, but the details allude me. Could anyone offer any insight on this
matter?</FONT></DIV>
