Re: [Paraview] [EXTERNAL] Unable to rescale properly the color map
Hi Luigi, I have the same problem when I display color contours with UNIX Timestamps. The instant solution is using Calculator filter. Subtract 160 from CellIDs, you may get correct results. # Of course I want to be fixed the problem about the precision of contour ranges, too.

Re: [Paraview] View geotiff in Paraview?
Hi Adam, >>> I can?t seem to select Warp by Scalar from the >>> texture map. Warp By Scalar couldn’t apply to Image data directly. So you should convert images to surfaces, and apply the warping filter. TIFF image -> Extract Surface -> Warp By Scalar (or Vector) If your images are not 1 or 3 channels (cf. includes Alpha channel), you should extract elevation channel(s) by Calculator Filter.

[Paraview] dataset_adapter with tensors
Hi all,
I'm trying to add 3x3 tensor data to vtkPolyData with Python.
The version of ParaView is 5.0.0 RC1 and 4.4.0.
The smallest example is here:
> import vtk
> import numpy as np
> from paraview.vtk.numpy_interface.dataset_adapter import numpyTovtkDataArray
> as da
> from paraview.vtk.numpy_interface.dataset_adapter import
> vtkDataArrayToVTKArray as va
>
> m0 = np.array((
> (0, 1, 2, 3, 4, 5, 6, 7, 8),
> ))
>
> d = vtk.vtkPolyData()
> d.GetPointData().AddArray(da(m0, 'data'))
>
> m1 = []
> for i in range(9):
> m1.append(d.GetPointData().GetArray('data').GetValue(i))
> print(m1)
>
> m2 = va(d.GetPointData().GetArray('data'))
> print(m2)
m1 is good, but m2 is transposed.
Is this a bug of vtkDataArrayToVTKArray?

[Paraview] vtk.vtkPoints.SetData()
Hi all,
I’m going to generate pointclouds from CSV with Programmable Filter.
On ParaView 4.1 or older, the script works:
from paraview.vtk.dataset_adapter import numpyTovtkDataArray as da
from paraview.vtk.dataset_adapter import vtkDataArrayToVTKArray as va
pdi = self.GetInput()
X = va(pdi.GetRowData().GetArray('x'))
Y = va(pdi.GetRowData().GetArray('y'))
Z = va(pdi.GetRowData().GetArray('z'))
pts = vtk.vtkPoints()
pts.SetData(da(hstack((X, Y, Z)), 'Points’))
But on 4.2 or newer, the script isn’t work:
from paraview.vtk.numpy_interface.dataset_adapter import
numpyTovtkDataArray as da
from paraview.vtk.numpy_interface.dataset_adapter import
vtkDataArrayToVTKArray as va
pdi = self.GetInput()
X = va(pdi.GetRowData().GetArray('x'))
Y = va(pdi.GetRowData().GetArray('y'))
Z = va(pdi.GetRowData().GetArray('z'))
pts = vtk.vtkPoints()
pts.SetData(da(hstack((X, Y, Z)), 'Points’))
The error message is as follows:

How can I use SetData() method on latest ParaView?

Re: [Paraview] Creating time dependent data from ascii file
Hi Hedieh, Usually transient sources are prepared as sequential files (ex. file.vtk, file0001.vtk, …). If you want to read your data as it is, you should use Programmable filter. But the technique is tricky and heavy to handle. I think it’s better to split your file as X,Y,Z,V. You can use CSV Reader bundled in ParaView. Any texts separated by commas, whitespaces, or other separators are available.

My impression is that I have to apply this filter several times to different sources. Am I right? Thank you.

Most of the 3D programs including ParaView draw objects as groups of triangles. That’s depends on today’s 3D rendering pipelines such as OpenGL, DirectX, etc. Please googling the keywords: ‘vertex shading’ Even though you read your data as structured grid with point values, ParaView should immediately triangulate all of the rectangles, and interpolating the values between points of the triangles. # If you visualize cell values, there are no problem caused by interpolating. The attached image is one of the solution. 1. read your data 2. make a ‘fine resolution' Plane source with same size to the original (for example, 200x100 structured grid) 3. apply Resample With Dataset filter The result looks nearly-symmetric for me.

With NS solvers, the velocity vector in an axis system bound to a wall should ALWAYS be zero at the wall (moving wall or not moving wall): this is the adherence condition. As LIC needs a non zero vector at the wall in an axis system bound to the wall, you cannot use the velocity vector, and you MUST use the skin friction vector. My NS solver gives the three components of the skin friction vector in an axis system bound to the wall as three scalar arrays. So I have to use the PV Calculator filter in order to build the vector array from these three scalar arrays, something like Friction_vector = x_component*iHat+y_component*jHat+z_component*kHat But you may also use the Calculator filter to build the friction vector from the stress tensor and the normal vector at the wall.

Hi Utkarsh, I already checked it, but there are no information about getting all values of VTKTable with NumPy. Now I'm using for-loops and the GetValue(i, j) function, but it's not smart. Do you have any other information?

[Paraview] Saving Programmable Filter as a PNG image
Hi all,
I want to save vtkImageData as a PNG image.
The vtkImageData is generated by Programmable Filter.
My PV version is 4.1.0.
I have a small CSV data as below:
1,0.5,0
0.5,1,0.5
0,0.5,1
I opened the data and applied the Programmable Filter as below:
#Output Data Set Type: vtkImageData
#Script:
inp = self.GetInput()
out = self.GetOutput()
out.SetDimensions(4, 4, 1)
out.SetOrigin(0, 0, 0)
out.SetSpacing(1, 1, 1)
ca = vtk.vtkUnsignedCharArray()
ca.SetName('image')
ca.SetNumberOfComponents(3)
ca.SetNumberOfTuples(9)
out.GetCellData().SetScalars(ca)
for i in range(3):
for j in range(3):
ca.SetTuple3(i * 3 + j, inp.GetValue(i, j).ToFloat() * 255.0, 0.0,
0.0)
#RequestInformation Script:
from paraview import util
inp = self.GetInput()
util.SetOutputWholeExtent(self, [0, 3, 0, 3, 0, 0])
I got a 3x3 matrix image on the View.
Then I saved the data as a PNG image, I got the warning and no image was found:
Warning: In
/Users/kitware/Dashboards/MyTests/NightlyMaster/ParaViewSuperbuild-Release/paraview/src/paraview/VTK/IO/Image/vtkPNGWriter.cxx,
line 198
vtkPNGWriter (0x11c80a540): PNGWriter only supports unsigned char and
unsigned short inputs
How can I save the Programmable Filter as an image?

[Paraview] Visualize CSVs as Images
Hi all, I have sequential CSVs which only have contour values as m*n matrices. I want to visualize and animate them like VTK Images (arrays of pixels), but PV's CSV Reader requires values of each point. My CSVs are exported and refreshed by other asynchronous softwares, so I have to read the CSVs into PV without pre-processing them. I think Programmable Source filter may be suitable, but I don't know how to read sequential datasets with it. Any ideas?

The interpolation and integration method (both space and time domain)
of ParaView are very simple, but not ideal.
ParaView splits all cells into tetrahedra or triangle and
interpolate values with linear algorithm.
I haven't research FIELDVIEW's method yet, but it may be different from PVs.

I'm using the Probe Location filter to extract data from a 3D CFD solution
for an internal flow, and I'm not getting the data that I should be for
some (but not all) of the points. The dataset is approximately 7 million
nodes saved in Ensight format.
I'm comparing the data returned by Paraview to the data at the same
locations in FieldView. For licensing reasons, I would prefer to use
Paraview for this research, but I also need accurate solutions.
For two representative probe locations, I have the following results:
x y z pv_density fv_density pv_pressure fv_pressure
0.3912-0.0376-0.05660.9040 0.904067779.9
67779.9
0.3912-0.0426-0.05160.8275 0.862365849.0
66176.3
The first point matches precisely between Paraview and FieldView. However,
the second point is substantially different. In addition, the velocity at
point two is {0,0,0} indicating that the point is on the boundary, though
it is not actually.
Looking at color plots in Paraview, the color under the point location
clearly matches the numbers from FieldView. I've uploaded plots showing
pressure in the plane containing the two locations here:
https://dl.dropbox.com/u/**744216/probe1.pnghttps://dl.dropbox.com/u/744216/probe1.png
https://dl.dropbox.com/u/**744216/probe2.pnghttps://dl.dropbox.com/u/744216/probe2.png
The values are wrong for points that are close to the boundary, and match
FieldView for points away from the boundary. I have also tried importing
the locations from a CSV file and using the Resample Dataset and get the
same values.
Can anyone shed light on why this is happening?

Re: [Paraview] animating multiple vtp files
Hi Jelle,
There are 3 problems to be solved:
1) Combine .pvd files as a transient dataset
2) Generate ParticlePaths
3) Animate ParticlePaths
1) is a FAQ:
http://www.paraview.org/pipermail/paraview/2007-June/005165.html
...and 3) too:
http://www.mail-archive.com/paraview@paraview.org/msg01966.html
But I don't have a good idea about 2).
Of course ParaView have ParticlePath filter,
but that couldn't work with my datasets.
So I always convert particle data into pathlines and read them.

Hello
The software package I used to simulatie particle behaviour has the option to
create .VTP files,
which I could use to visualize the particle paths in Paraview.
(There is an attached image that shows the created files)
I'm able to visualize my fluid domain in Paraview but I don't understand how
I can visualize and animate the particle paths.
I will be glad if someone can help me to animatie the particle paths.
Kind regards

[Paraview] TimestepValues of Parental Sources
Hi all, I'd like to export integrated values of unsteady sources with Python. I'm planning to get sources by GetActiveSource() method.

Re: [Paraview] Python Script: Rescale to Data Range
Hi Roman, I have an other solution about this problem using Python. The code takes you the ranges of any values: sm = servermanager.Fetch(your_source) sm.GetCellData().GetArray(your_value).GetRange(0) ...and you can apply them to your Color Maps. You should apply your source's and value's name (ex. 'Slice1' 'Velocity'). If you want to get point data, change GetCellData() to GetPointData(). And if your sources have high-dimensional value (such as vectors) and want to get the range of n-th component, change n value of GetRange(n). If your sources are MultiBlock dataset, you should get only one block before getting value as below: sm.GetBlock(N).GetCellData().GetArray(your_value).GetRange(0) N is the number of blocks. # Now I have not enough samples, perhaps the codes couldn't work, sorry.

Hi Mohamad, If you do not mind doing more steps: 1. Save your source as XML-VTK formats. 2. Re-open the XML-VTK Data.

Re: [Paraview] Screenshot sizes on pvbatch
Mirko and Gena,
Thanks for your reply.
I tried both advices.
I couldn't access vtkRenderLargeImage from pvbatch,
but the 'Magnification' option takes good results!
I always export large screenshots because of resizing
(for pseudo-antialiasing), so this technique is very nice for me.

[Paraview] Getting point values on pvbatch
Hi all,
I'm trying to get point values from several sources on pvbatch.
I'm using ParaView 3.14.1 with local client (single CPU) mode.
My pipeline is as below:
source.vtm
| --CellDatatoPointData1
| |-/ResampleWithDataset1 (Input)
| --IntegrateVariables1
|-Line1
| --/ResampleWithDataset1 (Source)
--ResampleWithDataset1
The original source (source.vtm) is XML MultiBlock including Pressure values.
Now I'm debugging my codes on Python Shell.
First I get sources as below:
GetSources().keys()
[('IntegrateVariables1', '2579'), ('CellDatatoPointData1', '2293'),
('source.vtm', '2175'), ('ResampleWithDataset1', '2490'), ('Line1', '2305')]
original = GetSources()[(source.vtm, 2175)]
source = GetSources()[(CellDatatoPointData1, 2293)]
integrate = GetSources()[(IntegrateVariables1, 2579)]
line = GetSources()[(Line1, 2305)]
resample = GetSources()[(ResampleWithDataset1, 2490)]
And all sources are grabbed successfully:
original
paraview.servermanager.XMLMultiBlockDataReader object at 0x11d81c4d0
source
paraview.servermanager.CellDatatoPointData object at 0x11d81c490
integrate
paraview.servermanager.IntegrateVariables object at 0x11d81c3d0
line
paraview.servermanager.Line object at 0x11d81c450
resample
paraview.servermanager.ResampleWithDataset object at 0x11d81c390
Next I want to get these values:
a) original's coordXs, coordYs, coordZs
b) source's Pressures
c) integrate's Pressures
d) resample's Pressures
For example, I can get Pressure's range as below:
source.PointData.GetArray(Pressure).GetRange()
But I'm missing to get each points' raw values,
and I can't find where the points' coordinates are.
Fortunately I can only get integrated value with GetRange()[0],
but I think it's not a good way.
How can I get each points' or integrated raw values and coordinates with Python?

0 0 0
0.4 0 0
1 0 0
0 0.25 0

CELL_TYPES 4
9 9 9 9
CELL_DATA 4
SCALARS scalar FLOAT 1
LOOKUP_TABLE DEFAULT
1.0

8.0
This source includes 4 Quad cells and Cell-based Scalar values.
These cells' area values are different.
If you apply Cell Data to Point Data filter, the ID:4 point's

Hi Leo Sam, Thanks for your replies. The bilinear integration method which Sam wrote was just I intended. I could open the PDF document on Mac OS X and iOS (iPhone/iPad). Additionally, I found a similar problems on Temporal Statistics filter. I prepared two transiend data sets. Case 1: t=1.0, scalar=1 t=2.0, scalar=2 t=4.0, scalar=4 Case 2: t=1.0, scalar=1 t=1.1, scalar=2 t=4.0, scalar=4 Both Temporal Average Values are 2.. And if I apply Temporal Interpolation filter and Temporal Statistics filter again, there are different results. The reason is the Temporal Static filter is just calculating sum average, and transient time values are not considered. I'd like to get time-weighted average values by Temporal Statistics filter.

Re: [Paraview] vtkXOpenGLRenderWindow Error
Hi all, I've been trying to solve the problem. I found an important setting about it. Our ParaView is running on shared Linux cluster, so we operate ParaView with VNC Client. My VNC setting is very simple as below: vncviewer -geometry [width]x[height] But other users' settings are little different: vncviewer -geometry [width]x[height] -depth 32 The -depth option is critical. Maybe this option influences OpenGL setting of VNC, and ParaView gets into GLX errors. I suggested removing -depth option and restarting VNC server, then our ParaView executed perfectly.

Hi Utkarsh, Thanks for your advice. I tried patchelf, but I couldn't get expected result. The best way now I found was to add a path to /usr/local/paraview-3.14.1/bin. I'll do it for a time.

Re: [Paraview] libQtHelp.so.4 error
Hi Utkarsh, I had been trying to solve libQtHelp errors. Finally I succeeded to run my ParaView. I missed two important settings. First one was about Qt. Qt 4.6.2 was pre-installed on CentOS 6.2 and I additionally installed Qt 4.6.4 from tarball, so both versions of Qt were mixed on my CMake setting. My old ParaView on CentOS 6.2 looked no problem, but it referred pre-installed Qt 4.6.2. On the other hand, CentOS 5.3's Qt was 3.3, so it couldn't be referred from ParaView (it was already built with Qt 4.6.4). When I changed QT_QMAKE_EXECUTABLE as /usr/local/bin/qmake from /usr/bin/qmake-qt4 (pre-installed qmake) and re-configured on CentOS 6.2, all Qt settings were updated. Second one was about LD_LIBRARY_PATH as you mensioned. My ParaView (built with Qt 4.6.4) still dumped libQtHelp errors. If I did export LD_LIBRARY_PATH=/usr/local/lib, my ParaView ran. And also I modified /etc/ld.so.conf, they ran too. Thanks for your advices!! Magician On 2012/04/25, at 22:19, Utkarsh Ayachit wrote: Looks like /usr/local/lib is not a default path where your CentOS looks for loading libs. The ParaView from the binary dir works since it uses rpaths for all libs and it has the rpath for the Qt libs too. That gets removed on install and hence the issue. Try googling around, there must be a way to extend your default lib search path. Utkarsh On Tue, Apr 24, 2012 at 8:51 AM, Magician f_magic...@mac.com wrote: Hi Utkarsh, Thanks for your Advices.

But when I started ParaView, I got an error about shared QtWebKit library. I made a symbolic link of libQtWebKit.so.4 in /usr/local/lib/paraview, then ParaView was started successfully.

Re: [Paraview] PV3.14.1 STL reader *could* be broken.
Hi Frank, I have same errors about STL Reader on ParaView 3.14.0. When I read STL data on Linux (CentOS 5.3), ParaView may be terminated irregularly. If on Windows (Windows XP SP3), ParaView dumps errors, but still works. And these problems may be depends on ASCII STL data only. Binary STLs are imported safely. If you want to import STLs right now, how about using Binary format? Some ASCII to Binary STL converters are distributed on the web. And also I hope above bugs are modified.

[Paraview] Pick exact points on nodes
Hi, everyone. I want to probe nodes' values and major distances between 2 nodes. ParaView's functions such as Point Source, Probe Location, Ruler can pick points on sources, but they seem not to be able to pick sources' nodes exactly. How can I do them?

Re: [Paraview] Surface Development on ParaView
Thank you, Ken. I tried Calculation filter and got a good result! I used acos() function, so I couldn't extract whole cylindrical surface. But fortunately, my source data is quarter or half one. So it wasn't a problem for me. At first, I thought the Calculator just as a calculating tool with Scalar or Vector values. But on your advice, I believed that is one of the typical post-processing tool of ParaView.

Hi. Now I'm trying to control ParaView's camera angle with Python. I could get Active Camera object by GetActiveCamera() and try SetPosition() etc. But I Couldn't find function as Center of Rotation on Adjust Camera panel. How can I control it with Python? And also I want to get a ParaView's Python reference. We can find scripting tutorials on Users' Guide or Wiki, but it's very difficult to find unpopular functions. Is there a document on which all Python functions are introduced?
