Axes order of numpy array

[snownontrace]

Hi Marco,

I noticed that vedo.Volume uses the xyz order instead of conventionally used zyx. For example, when loading an image with vedo.load(image), the array order is xyz, but the io.imread(image) from skimage and tifffile etc. returns zyx. I am swapping x and z for now, but it might be the best to use zyx order by default.

Thanks!

Hi! You are right and this is quite annoying.. vedo always assumes real world coordinates and I'm afraid it is too late to change convention on this one.. But I understand it can be a source of confusion.
I can add some documentation and maybe a keyword option , something like
Volume(..., assume_zyx=True)
is maybe helpful?

Yes, that would be very helpful! If more vedo users process scientific image data, it might be worth making assume_zyx=True by default.
