Sign only reliable for watertight meshes? #4

Hi,

as in Robert Bradson's code, I assume that the inside/outside test only works for (more or less) watertight meshes, right? I am specifically referring to line 173 in the code.

Thanks!

That's right. If the mesh is not watertight, then inside/outside is ill-defined, so you won't likely get a consistent/meaningful result.

Thanks for the clarification!
