[Paraview] Scaling cylinder glyph's radius and height individually

[Ahmad .]

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 <paraview_home>/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!

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!

Best,
Ahmad

Dear community,


When I try to scale cylindrical glyph objects by a 'Scalar', it scales both the radius and height of the glyphs.

Is there a way to scale the radius by a Scalar1, and the height be a Scalar2?


I have an unstructured grid, and for each point I want to create a cylinder that can have an arbitrary radius and height.

I thought Glyphs would be the way to go, but I'm kind of stuck with this issue.


Any help is much appreciated; or if you can recommend a different way to achieve the above-mentioned please let me know!


Best,

Ahmad
