Hello, Utkarsh. The screenshots I have sent have been made with PV-3.10.0-RC1-Linux-x86_64 on CentOS 5.5. I performed the same screenshot test with PV 3.8.1 on Windows Vista, but I had not this color problem, neither the window over picture problem of Aurélien Marsan. I will install

[Paraview] Python questions

2011-02-10 Thread James Perry
Hello, We are attempting to use Paraview to visualise some data from a simulation. At present we have a standalone Python script that converts the data into a legacy VTK file which Paraview can read. Ideally we'd like to integrate the script into Paraview as a programmable source so that the

Hello James I don't believe this is a bug. I have used the ProgrammableSource and was able to render a grid without any difficulty. What is missing in your procedure is most likely setting the WholeExtent. try loading this script and you'll get a rendered image paraview --script=state.py

Utkarsh, I have performed the same screenshot tests on Windows Vista 32 bits with PV 3.10.0-RC1. No problem. The picture is always as expected, with the LIC representation being colored by the pressure variable in bot cases, offscreen rendering checked or unchecked. So the LIC color by

[Paraview] extract location of minimum

Dear Paraviewers, I would like to extract the location of a minimum value from a data set in pvbatch I were able to find the value of the minimum with mm=MinMax(Uzcomponent) mm.Operation=MIN mindata=sm.Fetch(Uzcomponent,mm,mm)

Re: [Paraview] extract location of minimum

2011-02-10 Thread David E DeMarle
The min max filter unfortunately doesn't keep track of which tuple and processor it found the min in so you can't get back to the particular point or cell it came from. Instead of using fetch and minmax, try using a values selection. Set the value to be that minimum value. Once you extract the

I'm pretty new to paraview so could be doing fundamentally wrong here, but here's my issue... I have paraview 3.10 compiled/installed from source on Ubuntu 10. I'm using a python script to connect to pvserver, iterate over a bunch of vtk files, do some stuff, and saving the output as a png. I'm

Hi Karl, It sounds like a memory leak problem. Have you tried opening the System Monitor in ubuntu and watching the memory usage of pvserver as you run your script? Can you post your script so we can take a look at it, maybe you aren't cleaning up after you process each file? You can pass

[Paraview] Amazon EC2 Cluster + Paraview

2011-02-10 Thread Matthew Dillon
Just curious if anyone has any experience setting up a Paraview server on Amazon's EC2 platform. I have compiled VTK a few times in the past, but I am spinning my wheels trying to square away offscreen rendering and parallel processing. I know this doesn't necessarily need to relate to EC2, but I
