[Paraview] PV 4.01 How to get screenshot with menu
I do a screenshot but the menu is not included (only the contours), How does one include the menu?

[Paraview] Paraview Benchmark and IceT timings
Hey all,
I am trying to do a benchmark, in order to be able to compare our GPU cluster and our Supercomputer. The GPU cluster has one Nvidia GTX680 per node
and 10G ethernet, while the supercomputer has no GPU's and Infiniband
In short, i open a file with 31 million triangles, run D3() to divide it over the processes, and render it to a 1600x1200 renderview, using a python
script (attached) and pvpython (paraview 3.98.1).
However, i am running into some unexpected deviations in my frame render times on the GPU-cluster, when using multiple (8+) nodes. Most frames render
in a constant time, but every so many frames i get one 2 to 3 times as slow. The output of the benchmark module doesnt shine much light on the
subject: All processes report the same, much higher frame time for these frames, so it is not clear if one process is slowing the whole down.
Our initial hunch was that it might have to do with the compositing step: Since the infiniband is much faster in terms of latency and throughput, this
step might be more efficient on the Supercomputer.
My question is, is there a way to separate the benchmark times of the rendering
and the compositing part of each frame?
Or is there any other advice on pinpointing the performance culprit?
regards,
Tijs de Kler

Re: [Paraview] Writing Images at certian time Steps using pvpython
Hi Burlen,
Thanks for your reply. Actually when I mentioned final time step at 1
to get the image; by 1 I actually was referring to the the time. ( The
time step related to this time (1) is time step 40)
I see what time is relating to what time step by using the
"AnnotateTimeFilter" and seeing the times interactively.
Considering that I know the correct time, still pvpython crashes when I try
to get the image at a different time by changing the following to
time=1 or any other time that exist in my simulation result.
RenderView1.ViewTime = 1.0
RenderView1.CacheKey = 1.0
RenderView1.UseCache = 0
AnimationScene1 = GetAnimationScene()
AnimationScene1.AnimationTime = 1.0
WriteImage('myImage.jpg')
Render()
Any ideas on what I could be doing wrong and how to get the image at a
different time using pvpython ?
I´d appreciate any help
Thanks

Re: [Paraview] Uncertainty visualisation worked example
Thanks Kyle, I guess what I was wondering is what sort of inputs it is designed for and meant to visualise. For example Is it something like: Data_field_1 = My values Data_field_2 = My uncertainties where MyResultsWithErrors = Data field 1 +/- Data field 2 In which case can it handle a case where the errors are asymetric? Or is is more Data_field_2 = 1 - the chance of Data_field_1 happening Also can it handle point sets or just connected surface data?

The values (e.g. "Data_field_1") should be set as the regular "Color by" array. The uncertainties (e.g. "Data_field_2") should be set as the uncertainty array for the representation. The uncertainties are expected to be positive and on the same scale as the input data. The higher the uncertainty value, the more "noisy" the surface will be rendered. For now, the representation only works with surface rendering.

Re: [Paraview] Writing Images at certian time Steps using pvpython
if you haven't yet it worth while to print the time values reported by
the reader. make sure it's not changing them on you. after that try to
get a stack trace showing where the crash occurs.

Hello,
My Data is of type h5 that I open using PFlotran HDF5 reader in
ParaView which are result of PFlotran simulation.
What I am trying to do is to write an image at a certain time
step and then finally write a batch job that writes an image for
each time step of the simulation result.
If I try to interactively go to a certain time step and then save
an image, everything works fine.
The problem is I have 40 time steps and I want to do the same
procedure often. So I saved my state file as a python script and
then set these few lines at the end of script just before Render().
RenderView1.ViewTime = 0.0
RenderView1.CacheKey = 0.0
RenderView1.UseCache = 0
AnimationScene1 = GetAnimationScene()
AnimationScene1.AnimationTime = 0.0
WriteImage('myImage.jpg')
Render()
My timeSeries start at 0 and the python script works just fine for 0.
If I change the following lines to 1 (my final time step) or
any other time step, then pvpython crashes, that is the following
change to the script makes the pvpython crash:
RenderView1.ViewTime = 1.0
RenderView1.CacheKey = 1.0
RenderView1.UseCache = 0
AnimationScene1 = GetAnimationScene()
AnimationScene1.AnimationTime = 1.0
WriteImage('myImage.jpg')
Render()
I used the trace to see what values I need to change to save an
screen shot for any time step and I ended up with ViewTime and
AnimationTime.
I have attached my script with this email. I would be grateful if
you could please tell me if I need to change more in my script or
add any additional lines to be able to get an screenshot of any
timestep rather than 0.
Thanks in Advance.

Re: [Paraview] Paraview Benchmark and IceT timings
There are some internal measurements taken, but I'm not sure there is any way to get to them without hacking on some code. You might be able to get a rough estimate of where the time is taken by playing with the input a bit. If you put a small number of large polygons on each process and force compositing on, that can give you an idea of the time to do (mostly) just compositing. Conversely you could load in a smaller number of polygons and turn compositing off. Not sure if that helps... -Ken On 8/22/13 2:40 AM, "Tijs de Kler" wrote: >Hey all, > >I am trying to do a benchmark, in order to be able to compare our GPU >cluster and our Supercomputer.
