[Paraview] vtk files with different time steps

Hi, I generate two sets of data files. One is called “particles_%.vtk” and the other is “fluid_%.vti” where % stands for the time the files represent. Time series of particles is [0, 30, 60, 90, ..., 15000 ] and the time series of the fluid is [0, 300, 600, 900, ..., 15000 ]. So I take a picture

Re: [Paraview] paraview hangs on volume rendering

I tried using volume rendering for the following example. It did work, but took a *tremendous* amount of cpu (i'm running core2duo @2100MHz) and was *very* slow. Is it supposed to take that much cpu and time? Also, how can i check whether PV is using my graphics card(if that is the problem)?

[Paraview] Problems with 'interpolate scalars before mapping' in v3.10

Hello everyone, I'm having some problems with porting my ParaView exporter plug-in to v3.10, because ParaView started using vtkCompositeDataSet internally instead of keeping components merged. The problem is in performing transformation of scalars to texture using vtkScalarsToColorsPainter class.

[Paraview] error:Cannot volume render since no point (or cell) data available.

Greetings, I loaded a scalar data (defined on a 3d grid) into paraview 3.10.1. When i try to change Representation to Volume, i get the error: Cannot volume render since no point (or cell) data available. But this can't be true since the Information tab shows that: Statistics:

Re: [Paraview] Problems with 'interpolate scalars before mapping' in v3.10

Nenad, I am not sure I understand where this code is being put. You say it's an exporter? Meaning it exports to something like a vrml/x3d file? But that doesn't seem right since you say you are using the PolyDataMapper. What is this plugin trying to achieve? Utkarsh On Wed, May 4, 2011 at 8:31

Re: [Paraview] error:Cannot volume render since no point (or cell) data available.

ParaView only supports volume rendering point data for 3D uniform grid datasets. You can apply a cell-data-to-point-data filter and the then volume render. Utkarsh On Wed, May 4, 2011 at 8:55 AM, pratik pratik.mal...@gmail.com wrote: Greetings, I loaded a scalar data (defined on a 3d grid)

Yes i was using builtin mode. But i ran it on the cluster and it worked!(client-sever mode) thanks!! pratik On Wednesday 04 May 2011 06:40 PM, Utkarsh Ayachit wrote: I am not sure what's the problem. I could easily volume render your dataset (image attached). Are you running in parallel or

Re: [Paraview] error:Cannot volume render since no point (or cell) data available.

Thanks for that! I used the cell-to-point filter and it is working perfectly ! pratik On Wednesday 04 May 2011 06:36 PM, Utkarsh Ayachit wrote: ParaView only supports volume rendering point data for 3D uniform grid datasets. You can apply a cell-data-to-point-data filter and the then volume

Re: [Paraview] vtk files with different time steps

I believe that the file series reader ignores the actual numbers that distinguish files series and just assigns them sequential integers for time (0, 1, 2, 3,...). If you think ParaView should be using the indices in the filenames for the time value (a reasonable request), then you should add a

Re: [Paraview] Problems with 'interpolate scalars before mapping' in v3.10

Dear Utkarsh, Thank You very much on Your answer. Yes, my plug-in is exporter, which means I define it in class derived from vtkExporter. It extracts all possible scene information from vtkExporter::RenderWindow object (in both Qt-client and python-client modes) and writes these data to very

[Paraview] Single Reader to Multiple Views

Is it possible to have a singe reader (reads in to a vtkMultiBlockDataSet) and have multiple views to display the data at the same time? For instance, Block 1 would have data for a sphere and Block 2 would have data for a 2D chart representing some statistic. Once you read the data, it will

Re: [Paraview] Single Reader to Multiple Views

I would think that it's possible but would take a bit of programming to work properly. If I were to try that I'd first look at the SLAC reader plugin as that does something fairly similar. Somebody else can probably give you better direction but the SLAC reader is a decent start. Andy On Wed,

[Paraview] using vtkInformation in 3.10

Hi All, I have a reader that gets the information object from it's output and adds some keys for downstream filters to use. This recently stopped working with version 3.10. Can anyone shed some light on what might have caused the change in behavior in version 3.10? Was this a deliberate
