What are the types of mesh problems my STL can have?
Open faces- this occurs when
there is missing data, resulting
in a hole in the surface
Self Intersections- this occurs
when triangles contain
mismatched coordinates, and
they do not line up as
expected.
This creates an error because
the surface can be in two
places at once, or create
areas with zero thickness
Inverted Normals- this occurs
when the coordinates for a
triangle are stored in an incorrect
order, resulting in the "inside"
face being inconsistent with the
surrounding triangles
