Isocaps between to isosurfaces of different isovalues

Hi,

I've recently been trying to fill the volume between two isosurfaces corresponding to different isovalues but can't find out how to do. Any help would be welcome. The objective would be to only have the green parts on the borders of my volume.

Thank you for your help

Hi, I have the same question. I wonder if you solved it already?

I am thinking about calculating the overlapping area of the isocap above the lower isovalue and below the higher isovalue. Not sure if it works.

Thanks.
