Connection of 2 surfaces in 3D with side faces (geological data)

Hello!

I have a problem I have been trying to solve for a long time. The task is to connect two surfaces, located strictly one above the other with drawing side faces. The surfaces are geological strata, which would be combined in geological model like this:

 

I was trying to use Extrusion of triangles in combination with CSGBuilder for getting an intersection of 2 extrusions, but this method working unstable (or, which is more possible, I'm doing something not right):

Maybe there is other way to get side walls of surfaces and merge them with surfaces into solid?

 

Thank you!

Some of the techniques described here may assist, but rely on the input surfaces being in the form of a raster

Thanks for the suggestion, but the option with voxels did not fit due to the large size of the data obtained and the pixel-like final image. So it might be suitable for work, but not for visualization.

 

Anyway, the issue was solved by a separate triangulation of each side face with a turn of 90 degrees in 3D space with the subsequent collection into one object
