Hi Ben,
I'll give it a shot:
- first turn your mesh into a surface data type without throwing out data (i.e.
all the nodes of the mesh will be preserved)
vmtkmeshtosurface -ifile mesh.vtu -ofile mesh_s.vtp -cleanoutput 0
- then compute the distance
vmtksurfacedistance -ifile mesh_s.vtp -rfile ref_surface.vtp -distancearray
Distance -ofile mesh_sd.vtp
- then turn your surface back to a mesh data type
vmtksurfacetomesh -ifile mesh_sd.vtp -ofile mesh_sdm.vtu
- last project your distance values onto your original mesh
vmtkmeshprojection -ifile mesh.vtu -rfile mesh_sdm.vtu -ofile mesh_d.vtu
At this point mesh_d.vtu should contain an array named Distance with the
desired values.
Hope this works for you
Luca

Virtualization & Cloud Management Using Capacity Planning
Cloud computing makes use of virtualization - but cloud computing
also focuses on allowing computing to be delivered as a service.
