    <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>
      <br>
      Best,<br>
