[Paraview] [ParaView] How to add slice thickness ?

[Cory Quammen]

Chaturi,

I'm still not clear on what your input is. Are you loading a series of
2D images? Is that working? What kind of data set do you get after
loading (look under the Information tab under Type:)? Do you see just
one slice when the data is loaded or an outline of a 3D box?

Please provide step-by-step what you are doing in ParaView up to the
point you want to specify the spacing between slices. Links to
pictures of what you are seeing are often helpful as well.

Thanks,
Cory
