[vtk-developers] Volume rendering update

[Aashish Chaudhary]

Hi all,

We have made some significant improvements to volume rendering since our
last update (Ref:
https://blog.kitware.com/volume-rendering-enhancements-in-vtk/,
https://blog.kitware.com/volume-rendering-on-ios-and-android/). Below is a
list of tasks that are either nearly completed and or are in VTK master as
of today.


   -

   Features/updates
   -

      Big volume support - Fixing failing tests. The idea is to split
      volume into smaller volumes and render them piecewise.
      -

      3x-5x clipping plane performance - For the same parameters, clipping
      is much faster now, the trick is to skip voxels that are clipped
by planes.
      -

      Depth and color data capture - User can use RenderToImage to render
      to a FBO and get depth and color texture which then could be utilized for
      other operations.
      -

   Bugs
   -

      Fixed gradient opacity not working for more than one components
      -

      Fixed clipping plane location is wrong in certain cases.
      -

      Fixed volume rendering invalid or bad for cell data
      -

      Fixed edges issue when rendering in multiple pieces (hard edges)
      -

      Fixed volume rendering not working in remote rendering mode with
      image reduction factor > 1
      -

      Fixed volume rendering not working in client-server mode
      -

      Fixed volume disappears when changing parameters
      -

      Fixed volume rendering not using the correct sampling distance
