support for meshes on main

[francesco-ballarin]

Hi, I am using itkwidgets<1.0 to visualize finite element meshes (sometimes 2D, sometimes 3D) and fields defined on them, often through pyvista.

itkwidgets goal on master branch is stated as

Interactive Jupyter widgets to visualize images, point sets, and meshes on the web.

while on the main branch it is

Interactive widgets to visualize images, point sets, and 3D geometry on the web.

with no mention of "meshes".

With this I would like to ask if users can expect support for meshes to be added back to main at some point in future, or if that is not something you are interested in anymore.

Thanks, Francesco

Hello Francesco!
Meshes are still supported on main. If you find something something unexpected in your tests, please let us know.

Thanks, then I must be confused by the documentation on main.

On master, I used to pass the geometries kwarg to itkwidgets.view, see https://github.com/InsightSoftwareConsortium/itkwidgets/blob/master/itkwidgets/widget_viewer.py#L965

I find no mention for it on main, see https://github.com/InsightSoftwareConsortium/itkwidgets/blob/main/itkwidgets/viewer.py#L217

@francesco-ballarin I am sorry for the confusion but you are correct, there is not support for geometries on main at this point in time. We absolutely intend to add support for geometries again, but at this point there is some additional work that needs to be done before that can be supported again with this newer version of itkwidgets. In the meantime though the master branch does still have this support.

Thanks @bnmajor for the clarification! Good to know that such support will be added at some point, I'll make sure to come back and test it when it will land on main (and then close this issue).

Would be nice if we can update geometries after first load: https://discourse.itk.org/t/adding-additional-geometries-to-viewer-changes-colours-of-outputs/5449/3

My main motivation was using itkwidgets within pyvista. Since the itkwidgets backend was removed from pyvista in https://github.com/pyvista/pyvista/pull/3737, I don't have any further interest in this, hence I am closing this. Feel free to reopen if someone else is interested in this for itkwidgets on its own, rather than within pyvista.

Hello, I am very much interested in the support for meshes in itkwidgets. Can we keep this open?
