yes, I think so

I think the help in the class refers to the signed distance transform 
from the STL mesh measured on each node of the structured data set

offset 0 should refer to the voxels (in your structured data set) 
intersecting your surface mesh

Let´s see if someone else can add more insights

good luck,
