Re: [Paraview] Scaling cylinder glyph's radius and height individually
Thanks Cory, that's the function I was looking for.
Got it working now 😊
I attached a working version for anyone interested; README inside with some
instructions

Ahmad,
First, I recommend that you try loading your plugin in the ParaView
UI, using the ParaView that you built your plugin against. Then, in
Tools -> Manage Plugins. Click on Load New... and select the file
libvtkPVGlyphFilterP.so. You should now be able to find your filter
GlyphP in the Filters menu.
Second, to instantiate the filter the way you are trying is correct,
but first you need to load the plugin. I believe you can do it this
way:
vtkSMPluginManager::LoadLocalPlugin("//libvtkPVGlyphFilterP.so");
HTH,
Cory

Re: [Paraview] Scaling cylinder glyph's radius and height individually
Sorry about that Cory; will keep this in the mailing list.
I have tried to implement your suggestion, and now I have generated a plugin
file "libvtkPVGlyphFilterP.so".
Please find the files I used to create this plugin in the attachment.
What I did after compiling the plugin:
1. Try to use the new class I made, like such:
`session_manager_->NewProxy("filters", "GlyphP")));`
where GlyphP is what I called my custom glyph filter (see the xml file in the
attachment).
2. Compile my application against "libvtkPVGlyphFilterP.so".
3. Run my application and get the following error:
ERROR: In
/home/ahmad/paraview/ParaViewCore/ServerImplementation/Core/vtkSIProxyDefinitionManager.cxx,
line 526
vtkSIProxyDefinitionManager (0x294d320): No proxy that matches: group=filters
and proxy=GlyphP were found.
I feel like I am missing an important step, which has to do with the XML file,
but I don't know how.
In the Plugin Wiki of ParaView the instructions I find after compiling are:
Then using cmake and a build system, one can build a plugin for this new
filter. Once this plugin is loaded the filter will appear under the
"Alphabetical" list in the Filters menu.
There are no instructions on how to use the new class in a C++ pipeline...
Any pointers on this?

Ahmad

Hi Cory,
Thanks for your reply.
I am trying to implement your suggestion of extending the vtkGlyph3D with this
additional "scaling by normals".
The idea seems quite straightforward. I was just wondering how to incorporate
this new class in my C++ pipeline.
Currently I create the glyph, and set its properties, like this:
vtkSmartPointer glyph;
glyph.TakeReference(vtkSMSourceProxy::SafeDownCast(
session_manager_->NewProxy("filters", "Glyph")));
controller_->PreInitializeProxy(glyph);
vtkSMPropertyHelper(glyph, "Input").Set(producer);
vtkSMPropertyHelper(glyph, "Source").Set(GetCylinderSource(glyph));
vtkSMPropertyHelper(glyph, "ScaleMode", true).Set(0);
vtkSMPropertyHelper(glyph, "ScaleFactor", true).Set(1.0);
vtkSMPropertyHelper(glyph, "GlyphMode", true).Set(0);
As you can see I am not directly working with vtkGlyph3D or vtkPVGlyphFilter
classes, but I am using the vtkSMPropertyHelper to take care of the boilerplate
code.
Right. Unfortunately, implementing my suggestion would require creating a
subclass of vtkPVGlyphFilter and importing that with a ParaView plugin. See the
ParaView Howto on how to add a filter to ParaView.
After I created a new class that has this extra scaling option, how would I go
about using this in such a pipeline? Do I need to 'register' my "ModifiedGlyph"
to the filter proxies to be able to do something like `NewProxy("filters",
"ModifiedGlyph")`?
Yes, that should do it. Your modified glyph class will be available once you've
imported the ParaView plugin mentioned above.
A quick question about setting the active normals. Is there an existing way to
do this, or would I need to do this myself? I would like to do this the same
way one would set the "Scalars":
vtkSMPropertyHelper(glyph, "Normals")
.SetInputArrayToProcess(vtkDataObject::POINT, "ScalingArray");
I think that should work.
Best,
Cory
Looking forward to your reply.

Hi Ahmad,
Alas, reading the code of vtkGlyph3D, you cannot orient by a vector
array different from the vector array used to do the scaling using the
functionality in ParaView. You would have to modify either
vtkPVGlyphFilter or its parent class vtkGlyph3D, to do this, and
expose the new VTK class through a ParaView plugin [1]. A simple
modification would be to add a ScaleMode, say VTK_SCALE_BY_NORMAL, to
vtkGlyph3D, and then set the active normals in your data set to the
vector by which you wish to scale. Then the "vectors" property could
control the orientation and the active normals would control the
scale. That's kind of kludgey, but it would be a fairly fast
modification to make.
HTH,
Cory

Re: [Paraview] Scaling cylinder glyph's radius and height individually
Just want to add that a programmatic (C++) solution is preferred rather than using the GUI I have a C++ pipeline where I can set the properties of the cylinder glyph with vtkSMPropertyHelper. I have looked in filters.xml under vtkPVGlyphFilter source proxy (file located in /ParaViewCore/ServerManager/SMApplication/Resources) to see what my options are, but there is only one "SetInputArrayToProcess" that takes a vector attribute as input; nothing about a vector specifically for orientation.. Suggestions on how to handle this issue, are very welcome; other approaches than mine as well! Van: Ahmad . Verzonden: maandag 8 januari 2018 20:52 Aan: paraview@paraview.org Onderwerp: Re: Scaling cylinder glyph's radius and height individually Following up on my own question, I found out that if I scale by "Vector Components" it is possible to change the length of the cylinders with the second vector index, and the radius with the first and third. I need to rearrange my attribute data as such: [radius_x, length, radius_z]. If I keep radius_x == radius_z, then the cylinder will not deform, and the cross section stays a perfect circle. See the image in the attachment please. BUT the problem here is that "vector components" also affects the orientation of my cylindrical glyphs. I can turn this off in the properties menu, but I need to orient my cylinders based on another vector attribute data... I feel I'm getting somewhere, but if someone could give me an idea on how to now orient my glyphs with another vector data than the one I use now for scaling, that would be much appreciated!
