Issue loading a volume

when trying to display the following file /data/visitor/ihma551/bm05/20240920/PROCESSED_DATA/SSD_battery/SSD_battery_0001/reconstructed_volumes/SSD_battery_0001_1_1_0000pag_db0020_vol.hdf5 as 3D / cube we get the following error:

Tested with 128Go of ram. Crashes after waiting a 'long time'. So probably when initiate the display

[t20100]

What is the size of the dataset?
Do you select the 3D view manually or is it opened automatically when opening the dataset?
Is it only with the 3D view? or with other as well?

The volume is 2048x2048x2048.

Other display mode (image stack...) works well.

The error arrives after a couple of minutes once clicked on the 'cube' view.

After discussion with @t20100 this clearly comes from the size of the volume. A warning could be add.

[payno]

Do we close it or do we want to add a warning for the next release ?
If we want to add a warning we will need to have a estimate on how much a system can handle or define an arbitrary threshold (number of cubes) to define when raising the warning

So the idea would be to warm the user if the volume exceed a certain size (2k*2k).
It can be either a warning in the terminal or a pop-up dialog.
