David,<br>
<br>
Thanks for confirming it. Does Kitware have a plan
to implement volume rendering for rectilinear
volume? You see the spectrum from vtkImageData, to
vtkRectilinearGrid, vtkStructuredGrid --- volume
rendering is implemented on both ends but not for
the middle one, which is a bit odd to the user. <br>
<br>
Best,<br>
Weiguang</div>
