[vtkusers] question about mapping textures to arbitrary shapes

[Wilson]

hi,
    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.  
    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?
