Create a 3D mesh from sparse spaced 2D segmentation

Thanks, Will! I mean that, if you consider the 3D volume as a stack of 2D images, I’ve labeled the same structure in images with index 0, 20, 40, etc.
The technique is isotropic thus each voxel is 10x10x10um, but the annotations are spaced by 200um.

See an image attached with blue labels and an attempt at interpolating in red.

And here is a sample data: https://www.dropbox.com/scl/fo/88uakloxk442oasw7nh5o/ABRmsYnEJ_FwYWPXbxEgi2c?rlkey=z6iwc4vop9fvqvis2fwtm1yap&st=81rm75rm&dl=0
