Re: [Paraview] Volume rendering rectilinear data

2018-04-27 Thread Weiguang Guan 

Hi David,

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.


Best,
Weiguang

You are correct it will not directly volume render vtkRectilinearGrids.

Use threshold filter (all values) to map to a vtkUnstructuredGrid for 
direct rendering but at a cost of memory explosion.
Apply the resample to image filter to map to vtkImageData for fast 
volume rendering, but at a cost of trading off precision for memory size.

Not that I know of.

We are more likely to make the conversion to image based volume rendering
automatic, faster and more precise.

You are correct it will not directly volume render vtkRectilinearGrids.

Use threshold filter (all values) to map to a vtkUnstructuredGrid for
direct rendering but at a cost of memory explosion.
Apply the resample to image filter to map to vtkImageData for fast volume
rendering, but at a cost of trading off precision for memory size.

[Paraview] Volume rendering rectilinear data

I didn't a test and I'm surprised that Paraview cannot do volume 
rendering on rectilinear data. Can someone confirm it or I made a mistake?
