That's indeed the reason by the "Resample to Image" filter was created
:). And it's expected to work in parallel for composite datasets too.
Of course, if you spot a bug, do let us know.

Re: [Paraview] Question about the ImageResampling Filter

2016-05-20 Thread Paluszek, Lukasz 
Hi Utkarsh,

I am always building Paraview from source on Linux with all the features I 
need, but there is no rush, I can wait for the next release or if I badly need 
this functionality I will pull it from the “master”.

A little background:
I was actually playing around when I came across the issue, what I want to 
achieve is to do fast volume rendering on unstructured meshes. The volume 
rendering algorithms in Paraview are ultrafast with VTK image files but 
painfully slow with unstructured grids. I constantly have an idea in mind to 
map unstructured meshes to image files and then do the volume rendering. Simple 
as it sounds I could not find an automatic way to achieve this, in the end I 
had to manually generate image files in a text editor. I also tried with the 
Gaussian Resampling, but this filter fails in parallel, each process generates 
its own image file but there is no communication between them, it is not 
possible to resample data onto these images nor is it possible to save them 
(Paraview saves data from just one process). I am still hoping to find some 
smart way of generating image files, ideally automatically refined based on 
some flow variables of interest and then map the unstructured grid data on the 
generated VTK images for fast volume rendering.

Regards,
Lukasz

Lukasz,

I'd suggest not to use 'ImageResampling' filter, it was a temporary fix and 
clearly is buggy. A new filter has been added to ParaView "master", name 
"Resample To Image". That would do what you want to do more reliably. What 
platform are you running on? I can send you links to the nightly binaries for 
the same.

[Paraview] Question about the ImageResampling Filter
