<div class="moz-cite-prefix">Hi 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>
