Hi, So I've been stumped and have been trying to think about a solution for this problem.

Suppose you have 2 hollow spheres, an outer sphere with a radius of 4 and inner sphere with a radius of 2. Though this example is relatively easy, I am looking to extend this to a general case. I am working with CAD and STL files, which are being stored as a series of Triangles and points, but I am struggling on figuring out on how to extract this volume.

Is there some way to create a region growing algorithm for this type of problem?

Thank you
