CheckOutwardNormals
Checks face/vertex list of closed triangulated objects to make sure all normals are outward facing.
Checks normals are outward facing and re-orders face if not.
Works with concave objects and with cavities. e.g. swiss cheese
Only works with triangular faces
Requirements: Function TriangleRayIntersection by Jarek Tuszynski
Input: faces, F (Nx3)
vertices, V (Nx3)
Output: corrected face list so all normals are outwards facing
list of any faces reordered
Assumptions: Normals are from clockwise orientation of faces. I.e. Right hand rule
Shape is closed and watertight.
No duplicate faces
Potential improvements: TriangleRayIntersection accepts multi-face, multi-ray input so should be able to speed up by removing the loop over the faces.
