Hello Adrian,
there is a way of combining level set files. After all, they are all
image files, so here's how you do it:
in case they are all produced from the same input image (i.e. they
have the same geometry), you can go
vmtkimagecompose -ifile ls1.vti -i2file ls2.vti -ofile ls_combined.vti
If you have more than 2, you'll have to call another vmtkimagecompose
on the result of the former;
in case they are produced from different input images (hence they
have different spatial extents) you'll first have to resample them onto
a common grid using vmtkimagereslice; let me know if this is your case
and I'll provide you with more details.
Best,
Luca
