Hello all,  
I have a legacy .vtk file with STRUCTURED\_POINTS in scalar format but the volume I want to render is not parallel to the global coordinate system. Can anyone tell me how can I convert this data to a STRUCTURED\_POINTS with unitcell geometry? Attaching the vtk file along with. (Cell parameters specified in the first line)  
FYI, I already tried creating a grid of all the points, but the file becomes too big!
