changing data in Slicer3DPlotter

[Kosach-p]

Hello! I am writing an application for a laboratory confocal microscope and decided to use vedo for 3D visualization, due to its obvious advantages. However, I ran into this problem. I use Slicer3DPlotter to study 3D image slices, and quite often I need to change the data in Slicer3DPlotter. The problem is that I do not know how to do it! A simple replacement of the data in the array is not possible, since the size of the data is always different for me. And if I try to delete an object received from Slicer3DPlotter and create a new one, then sliders and other additional widgets are not deleted, which subsequently causes errors. Can you tell me how the vedo library is supposed to change data in the same "Slicer3DPlotter"? And is it possible to change the widgets in Slicer3DPlotter (like sliders)?

Hi @Kosach-p
I just pushed a dev version that implements the requested feature.
Please check out example:
examples/volumetric/slicer_set_volume.py

[Kosach-p]

I get the message "AttributeError: 'Slicer3DPlotter' object has no attribute 'set_volume'. Did you mean: 'get_volumes'?". My vedo version is 2026.6.1. Maybe there are some special features of the versions?

you need to install the dev version:

pip install -U git+https://github.com/marcomusy/vedo.git

It works very well, thank you! Do I understand correctly that the developer version has a lot of freedom?

Great!
The dev version includes new features that will be later on released in the official library.
You can safely use it.

Got it, thanks again for the help!
