Hi Dafang,

You can map the mesh data onto the grid using MapFieldDataOntoNodes or
MapFieldDataFromSourceToDestination. You are right to use CreateLatVol. Use
the unstructured mesh as the input to CreateLatVol (it will use the same
bounding box) and you can pad the volume and set the resolution that you
want. Make sure the mesh data is set to some value(s) (you can use
CreateFieldData/CalculateFieldData) and use one of the mapping modules. set
the maximum distance to 1 or some other appropriate value and set the
default/background value to 0. This should give you the results that you
