[Paraview] Info about macros in new Python shell (version 3.6.2)
Hi Ken, could you please give some information about using macros in new Python shell (ParaView 3.6.2)? If we check View - Tollbars - Macro Toolbar we can't see any new icon on the toolbar; if we check Show menu in the Macros tab inside Python shell, we can see the new menu Macros, but it is empty. (The link http://www.itk.org/Wiki/Python_GUI_Tools#Macros didn't give any information...)

[Paraview] rescale each frame
Dear Paraview's list, I was looking for an option to rescale the data range at each frame of an animation. In the mailing list archives, I have found an exchange about this, where Ken asked: Furthermore, the result could be highly misleading. The constantly rescaled colors would show shifts of the scalar over time that simply do not exist. Do you have some use case in which these concerns do not apply? And I do have a very simple one: in my non linear calculations, I want to emphasize the way the evolving internal variables modify the shape of some field of interest, independently of the field intensity evolution. I hope I am clear enough. Anyway, many thanks for all the work. Cheers, Martin. ___ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the ParaView Wiki at: http://paraview.org/Wiki/ParaView Follow this link to subscribe/unsubscribe: http://www.paraview.org/mailman/listinfo/paraview

Re: [Paraview] rescale each frame
This is fairly easy to do if you're using python. You could start off your time series with something like: contacts/ui/ContactManager?js=RAWmaximize=truehide=trueposition=absolutehl=enemailsLink=truesk=truetitleBar=falseborder=NONEeventCallback=ParentStub1263830196859zx=9qx28f80odc0# Show(someFilter) dpsF = GetDisplayProperties(someFilter) dpsF.ColorArrayName = 'someArray' dpsF.LookupTable = MakeBlueToRedLT(lowValue,highValue) and then each timestep you could update: dpsF.LookupTable = MakeBlueToRedLT(newLowValue,newHighValue) I'm not sure how you would do it through the GUI. Good luck, Peter.

Re: [Paraview] tube filter, surfaces aren't closed?
I'm guessing that this is a z-buffer precision issue. The nVidia card must be
using a higher precision z-buffer or doing something else that is preventing
the z-fighting that appears to be happening in the Mesa implementation.

Re: [Paraview] holes in distributed polydata
I can't find anything wrong other then there must be some sort of precision issue that is interfering with the decision of when to draw a polygon that is smaller than a pixel.

That should fix the problem. -Ken On 1/15/10 11:07 AM, burlen burlen.lor...@gmail.com wrote: Using the dataset below I can reproduce the issue on my workstation using 4 processes and both hardware and mesa rendering. burlen wrote: Ken, Here is a dataset that I am able to reproduce with: http://nashi-submaster.ucsd.edu/movies/PV/holes.tar.gz run with 96 procs.

Sorry I can see how that could be confusing. But just to clarify, there aren't actually any holes in the surface. Here is another zoom in of the same area where surface with edges is off and you can see that there are no holes. http://nashi-submaster.ucsd.edu/movies/PV/bug-zoom.png Now I also have hit a case where after running through D3 I got a hole at the process boundary. this run had 80 processes, the surface shown has dimensions of 5.5 x 10 units with 1500 x 2727quads with side 0.0036 units. http://nashi-submaster.ucsd.edu/movies/PV/bug-d3.png I am only seeing this with the small quads and in parallel at process boundaries. Burlen Moreland, Kenneth wrote: Burlen, For the zoom in, you say there are no holes/lines, but in the image I see a grid of lines. It looks like you have a bunch of little quads with spacing in between them. Is this the case? If so, then the hole artifacts you see on the bottom of the screen are probably simply aliasing artifacts. They are places where the pixel happens to align right where the gap is. I can't think of an easy way around this (other than to modify your data to remove the gaps, if that makes sense). Anti-aliasing techniques such as oversampling or smoothing would probably fix the problem, but they would also break the parallel rendering so they are no good. -Ken On 12/5/09 12:18 AM, burlen burlen.lor...@gmail.com wrote: its ugly but I get a lot better performance by splitting the work up dynamically with a small grain size. in the run shown below there are only 16 processes but there are a whole lot of process boundaries. I was able to reproduce it on a second system today. these holes are pretty non-deterministic in where they show up. moving the camera they can show up in different places. Which makes sense if this is related to some parallel rendering/finite precision issue with all those process boundaries. The small size of the quads are
Re: [Paraview] netCDF reader
I'm not sure vtkImageData (and everything that uses it) really supports
negative spacing. See, for example, this email thread:
http://www.vtk.org/pipermail/vtkusers/2009-May/100989.html.
I agree. And that's why I have added the function fabs to make positive the
tolerance variable.
From ParaView3/VTK/IO/vtkNetCDFCOARDSReader.cxx (line 105...)
this-Spacing
= (this-Coordinates-GetValue(dimLen-1) - this-Origin)/(dimLen-1);
this-HasRegularSpacing = true; // Then check to see if it is false.
double tolerance = 0.01*this-Spacing;
for (size_t i = 1; i dimLen; i++)
{
double expectedValue = this-Origin + i*this-Spacing;
double actualValue = this-Coordinates-GetValue(i);
if ( (actualValue expectedValue-tolerance)
|| (actualValue expectedValue+tolerance) )
{
this-HasRegularSpacing = false;
fprintf(stderr,HasRegularSpacing = false);
break;
}
}
As I have written, if a coordinate variable goes from 90 to -90
(decreasing) with dimLen=7
(-90, -60, -30, 0, 30, 60, 90)
then Spacing variable is (-90 -90)/6 = -30 so negative, as tolerance
value equals to -0.3
expectedValue for i equals 90 +30 = 120 instead of 60 !
Consequence you get a HasRegularSpacing = false whereas the grid is
regular.
Put a simple fabs solves the problem
double tolerance = fabs(0.01*this-Spacing);
Is it clearer ?
No. I already understand that if the tolerance gets a negative value, the
HasRegularSpacing check will fail even if the spacing really is regular.
And I understand how using abs will fix that.
My point is that if the spacing is negative, then you cannot use a
vtkImageData because vtkImageData does not support negative spacing. And
the only reason for the HasRegularSpacing check is there in the first place
is to decide whether to use a vtkImageData.
So, the code would be clearer if there was a statement like
if(this-Spacing=0.0) { skip HasRegularSpacing check and use
vtkRectilinearGrid instead of vtkImagedata }. But regardless, the code ends
up doing the right thing even if technically HasRegularSpacing is set to
false instead of true.
- Test on units should be case independant
line 133, units.find( since )
I have netCDF files where since is typed with uppercase (generated by
ferret software from the NOAA/PMEL).
That is easy enough to change.
Do you mean that the user have to change it by himself using ncrename
(netcdf operators).
I hope not and I consider that it should be treated within the reader. A
user does not care
about a typology of an attribut.
Having said that, I don't know how to lowercase a vtkStdString.
I mean it is an easy fix in the code. I checked in a fix this morning.

[Paraview] A simple question
Consider an arbitrary surface with tangent vectors defined on it. How do you do for computing streamlines on such a surface? I mean how do you place seed points? Placing seeds on a shere or on a line does not work since of course seed points are not on the surface. _ Téléchargez Internet Explorer 8 et surfez sans laisser de trace ! http://clk.atdmt.com/FRM/go/182932252/direct/01/___ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the ParaView Wiki at: http://paraview.org/Wiki/ParaView Follow this link to subscribe/unsubscribe: http://www.paraview.org/mailman/listinfo/paraview
Re: [Paraview] A simple question
Try using Stream Tracer With Custom Source, and passing an extract selection from the surface as the seed input. There are some caveats to this if working in parallel.

[Paraview] Exporting ICEM CFD Mesh to ParaView
Hi, I'm trying to export a mesh generated in ICEM CFD to ParaView. I realized that I can export the mesh to Exodus II format and then open it with ParaView, but no information about the parts of the mesh is loaded, just the blocks. Any reader available to export geometry and mesh from ICEM CFD to ParaView ? I would like that the MultiBlockDataSet generated as result have information about the parts created in ICEM CFD.
