Re: [Paraview] Is it possible to group vtkImageData objects?

Hi Jimmy, Try "Append Attributes". This will yield a single vtkImageData that has several point data arrays, or "attributes". As long as the input vtkImageData have the same dimensions, this filter will do what you like. You can then pick which array you want to view with the Volume

Re: [Paraview] Problem compiling ParaView with NMake

Hi Thomas, I strongly recommend using the Ninja generator for building ParaView with Superbuild on Windows. It will build much faster than if you use other build generators, and will take care of the particular problem you are seeing as -j is a Ninja option that controls the level of build

[Paraview] Problem compiling ParaView with NMake

Hallo everyone, I tried to compile ParaView for Windows 10, using the superbuild of version 5.4.1 and NMake Makefiles as generator. After the execution of nmake, I get the following error: -- NMAKE : fatal error U1065: invalid option 'j' Stop. CMake Error at

[Paraview] Is it possible to group vtkImageData objects?

Dear community, Is it possible with ParaView to group vtkImageData objects in a single file format? I would like to import a couple of regular grids (i.e. vtkImageData objects) as a single file, rather than as grid_1.pvti, grid_2.pvti, etc... Once imported I would like to simply select which

[Paraview] ParaView VR - issue with new steam vr

Be aware if you are using the ParaView VR version with OpenVR support that a recent driver update from steam has introduced some issues causing events to be processed with delays. We should have a fixed version up in a week or so. Thanks Ken -- Ken Martin PhD Distinguished Engineer Kitware

Re: [Paraview] Programmable filter VTK/numpy

Hi Edo, Documentation for the VTK/Numpy adapter can be found here: https://www.paraview.org/ParaView/Doc/Nightly/www/py-doc/paraview.vtk.numpy_interface.html?highlight=numpy_interface#numpy-interface-package You will likely be interested in the dataset_adapter module that provides a convenient

[Paraview] Remote rendering with pvpython + grab remote image data

Hi there, is it possible to let pvpython render images remotely on a pvserver instead of locally inside the client? If I start a pvserver on a headless machine and run the following script in a pvpython client, a window pops up on the client and shows the cone: from paraview import simple

Re: [Paraview] Accessing particles generated by ParticleTracer

Hello Regarding the Programmable Filter, you are right, there is no way to specify it upstream, you would need to keep a list of previously deleted particle that should stay deleted, definitelly not a great solution. Regarding the inheritance, you are right as well, but keep in mind that

Re: [Paraview] [EXTERNAL] D3 filter crash

Don’t forget that each pvserver can’t tell that it is sharing the memory with siblings. Thus, you care about memory use at the node or computer level. In theory you are correct regarding D3. It rebalances work, and also creates ghost cells around processor boundaries. But, it is an old,

Re: [Paraview] [EXTERNAL] D3 filter crash

Hi Alan, The memory inspector turns back about 1% usage per core, so no overload here. Running 12 instances on a 16-core machine. Note: the same case runs fine in serial on the same machine, I’m just trying to speed up the data processing, as well as prove out some scripts I’m building for

Re: [Paraview] [EXTERNAL] D3 filter crash

Kill it, that’s ridiculous. My guess is that you need more nodes? Before running the D3 filter, try View/ Memory Inspector. If any nodes are over about 60% or 70%, you either need more resource, or less data. I’m curious – why are you running the D3 filter? Alan From: ParaView

Glad to hear it works! A disclaimer -- I don't profess to write good Python code, just mildly functional Python code :) On Wed, Oct 18, 2017 at 2:11 PM, Dennis Conklin wrote: > Andy, > > > > That works! Thanks much! > > > > Now I just have to add it to every

Re: [Paraview] [EXT] Re: How to test for empty block in multi-block dataset

Andy, That works! Thanks much! Now I just have to add it to every filter I’ve ever written to protect them all against empty blocks! I’m amazed it took this long for this to come up! Dennis From: Andy Bauer [mailto:andy.ba...@kitware.com] Sent: Wednesday, October 18, 2017 1:47 PM To:
