[Paraview] color unstructed surface mesh using a field on structured grid

[Yongcheng Zhou]

Dear all,

I am wondering whether it is possible to color a unstructured 
triangulated 3D surface using the scalar field stored in another
file with structured 3D grid. I can manually interpolate the
data on surface mesh from the 3D structured grid but thought that
paraview might have some proper filters for this purpose.

Thank you!
