Jesse Louis-Rosenberg@BrunoLevy01 Does the first surface need to be a closed volume or can it be any open surface?
@nervous_jesse a-priori it needs to be a closed surface, but it is not impossible to make it work for open surfaces, I will think about it....
@BrunoLevy01 Naively, one could construct an infinitesimally offset surface, and just use that.
@nervous_jesse it will be simpler (and safer regarding numerical problems) to change the algorithm a little bit: the parts of the algorithm that refers to the normals of the facets of surface A need to be duplicated, once with the normal of the facet, and once with minus the normal of the facet. Your question is a nice idea (gives a way of "volumetrizing" a surface, and 3D-printing it !)
@nervous_jesse ... I need to resist testing the idea ... I have a @#@! project proposal to finish before !!!
