volume operation crashes about vedo HOT 2 CLOSED

Hi Marco, Sorry for my late reply. I was just able to return coding.
Operation now it works great on logical operators also. Your interpolation under the hood saved my weeks.
I have used your interpolation and also vtkImageMathematics in order to Substract from one volume to another.
Without your interpolation, none of them was working
THANK YOU VERY MUCH and have a great day 🙇

Hi Umut, the problem is that the "+" sign means summing the scalar data inside volumes that have the same geometry.
If the volumes have different geometries (like voxel spacing or origin) some degree of interpolation is unavoidable.

I just extended operation() method to support logic operations, eg:

from vedo import Box, show
vol1 = Box(size=(35,10, 5)).binarize()
vol2 = Box(size=( 5,10,35)).binarize()

# vol = vol1.operation("+", vol2) # this will now give an error
vol = vol1.operation("xor", vol2)
print(vol)
show([[vol1, vol2], 
      ["vol1 xor vol2", vol]],
    N=2, axes=1, viewup="z",
)
