[Paraview] Registered texture images

[postgurke]

Hello,

 

I am using python scripts to import data into a ParaView (5.4.1) session. In order to keep the texture images in a saved state, I am registering them:

 


pathToTextureImage='path\\imagefile'
Display = Show(testvtp, renderView1)
Display.SetRepresentationType('Surface')
texProxy = servermanager.CreateProxy('textures','ImageTexture')
texProxy.GetProperty('FileName').SetElement(0, pathToTextureImage)
texProxy.UpdateVTKObjects()
servermanager.Register(texProxy, registrationName='ImageName')

 

Now, when I call this script multiple times (e.g. because I made changes to the vtp defining the texture plane), I will have multiple instances of my image in the pull-down menu for the texture. Is there a way to avoid this, either by checking if the resitrationName already exists or by deleting the multiple texture image from the list afterwards?

 

I have found this https://public.kitware.com/pipermail/paraview/2007-October/006126.html , but I cannot figure out how to use the code correctly in my case.

 

Also, is it possible to show only the images associated with the respective object in the pull-down menu? When I have many profiles with images loaded, the menu gets quite crowded and there is a risk of choosing an image not belonging to the current profile. 

 

Any suggestions on how to solve this are very much apprechiated. Thanks in advance!

Cheers,

Venke

Re: [Paraview] [EXTERNAL] Duplicate Layouts

[postgurke]

Hi Tobias

Thanks for your feedback. I will use your modifications the next time when I
need this.

rv1.ViewSize will hold the size of the first RenderView. But I think it doesn't
affect the size of the render window, only the view itself. Maybe this is still
helpful to you. I haven't done anything with more than two windows yet.

Cheers
Venke

Re: [Paraview] [EXTERNAL] Duplicate Layouts

[postgurke]

Hi Tobias

You could get the DisplayProperties of all your objects and then set them
accordingly in the new render window using the Python Shell. I have written a
short script for myself for this task --- however something is not quite
correct, as strange colorings sometimes appear after turning the model in the
second view. It can be fixed by making that object invisible and visible again,
but still Maybe someone more experienced can correct my answer in that
respect or has a better idea to tackle this problem...?

Here is my code:

rv1=GetActiveViewOrCreate('RenderView')
ALL=GetSources()

dispProps=list()
for i in range(len(ALL.keys())):
dispProps.append(GetDisplayProperties(ALL.values()[i]))

viewLayout1 = GetLayout()
viewLayout1.SplitHorizontal(0, 0.5)

rv2=CreateView('RenderView')
viewLayout1.AssignView(2, rv2)

SetActiveView(rv2)

for j in range(len(ALL.keys())):
SetDisplayProperties(ALL.values()[j],Visibility=dispProps[j].Visibility)

SetDisplayProperties(ALL.values()[j],ColorArrayName=dispProps[j].ColorArrayName[1])

SetDisplayProperties(ALL.values()[j],LookupTable=dispProps[j].LookupTable)

SetDisplayProperties(ALL.values()[j],DiffuseColor=dispProps[j].DiffuseColor)
SetDisplayProperties(ALL.values()[j],Scale=dispProps[j].Scale)

SetDisplayProperties(ALL.values()[j],Representation=dispProps[j].Representation)
SetDisplayProperties(ALL.values()[j],Texture=dispProps[j].Texture)

Re: [Paraview] Project polygon onto surface

[postgurke]

Adam,

Have you actually tried the filter? Because I think the output is exactly what
you're asking for: the "section" of the surface is the part of the surface where
the polyline is proceted onto it, hence a polyline with the regarding topography
values for the respective z coordinates.

Cheers

Re: [Paraview] View geotiff in Paraview?

[postgurke]

Maybe there is a way to achieve what you want for tiff - but I am not aware of
it.

Would it be suitable for you to convert your data to the Netcdf format? That you
can import and then use the warp by scalar filter to show the elevation. This is
what I usually do for topography data.

Cheers
Venke

Re: [Paraview] View geotiff in Paraview?

Hi Adam

I usually make a vtp File with just a frame from the image coordinates. Then I
can load the image as texture to the plane.

Hi Felipe

Would GetSources(), maybe along with FindSource and SetActiveSource help you?
ALL=GetSources() gives you a dictionary of all sources in your session.

Re: [Paraview] Lock Data Range for multiple attributes

[postgurke]

Hello Mathieu

Thank you for your answer. Unfortunately I don't quite understand :(. I tried to
duplicate the first and last point of LUT.RGBPoints (which are initially correct
before I look at a different attribute and switch back) - but this does not do
the trick. Sorry, I am not used to reading from State-Files. Do you have a short
explanation what you did in either the Paraview python shell or GUI to achieve
this?

Cheers

Re: [Paraview] Lock Data Range for multiple attributes

[postgurke]

Hello

Does nobody have a solution for this, or am I missing something obvious? 
The only thing I can do to fix the color ranges is separate the file into
multiple objects, but as one can only look at one at a time anyways (as they are
at the same location, obviously) and our model already contains a lot of
objects, this is rather bothersome...

Cheers
Venke

[Paraview] Lock Data Range for multiple attributes

[postgurke]

Hello All

Sorry to bother you again... I seem to miss something wanting to fix color scale
ranges for objects with multiple attributes. 
For example: I have a vtk-Plane with associated velocity and density values that
I can choose for coloring. When I imported the object, I set
LUT.RescaleTransferFunction(min, max) and LUT.LockDataRange = 1 for both
attributes (with different min,max, of course). In the GUI everything looks fine
at first, but when I switch the coloring from one attribute to another, ParaView
seems to ignore the checked "Lock Data Range" but switches to some Min/Max found
in the data. Maybe I misunderstand the functionality of "Lock Data Range"? Is
this the expected behaviour? If yes, what could I do to really fix the min,max
to my own specification? (I also tried to use a preset color scale with my
desired min,max, but this does not change the behaviour either.) 

Thanks for your support and any ideas on this,
Venke

... not just something like it, it is exactly the solution to my problem!

[Paraview] Import Preset color scale only if not already loaded

[postgurke]

Hello All

I haven't been able to find a solution for this, so maybe someone can give me a
hint...:
I am loading data via a python script into ParaView (5.0) and want to color it
with a specific color scale. I can load this scale with the script and apply the
coloring as desired but if the scale is already loaded, it will then be loaded
twice (or more). What I would like to do is check if the scale is loaded and if
yes apply it, if not first load and then apply.
I tought, that try/except would be my friend here, but applying a preset that is
not loaded doesn't throw an error but uses the default Cool to Warm scale
instead... What is also somewhat strange: if I had the specific scale loaded in
a ParaView session, but removed it from the list of presets, ParaView can
somehow remember it nonetheless and shows the data correctly (i.e. not with the
Cool to Warm scale but the specific one). 
Does somebody have an idea how I can avoid having the specific scale loaded
multiple times and still have the python script always producing the correct
visualization of the data set?

Here is the code I was trying:
...
zLUT=GetColorTransferFunction(ts)
try: 
zLUT.ApplyPreset(colorname,False)
except: 
ImportPresets(filename=colorname+'.json')
zLUT.ApplyPreset(colorname,False)
...


Thank you very much! 
Venke

[Paraview] Opacity mapping and image texture in ParaView 5.1.2

[postgurke]

Hello

 

I have an issue regarding the "enable opacity mapping for surfaces" (in the Color Map Editor) if the ParaView session contains another object that has an image loaded as texture. The problem occurs in ParaView 5.1.2 but not in earlier versions (tested with 5.0.1. and 4.3.1). I am working on Windows 64bit.

 

If I want to enable the opacity mapping for surfaces everything works as expected as long as I have no texture image. The behaviour is very strange: if I load a texture image in another object, this seems to be set to the background with the transparent volume cutting a window to see this image. I will include snapshots because I think that my explanation may not be very clear. With no opacity mapping enabled I can see the volume and the plane with the image as expected.

 

Should I do anything differently in the new ParaView to achieve a transparent volume along with the image texture object or is this "just" a bug? Thank you very much and best regards

Venke
