Changing edge orientations to optimize image matching quality in Tgi3D SU PhotoScan

We recently introduced a new "Flip if necessary" command within the "Image based Surface Modeler" Tool of Tgi3D SU PhotoScan. This command automatically changes the topology of the mesh to capture sharp discontinuities in the surface. The edges are flipped as in the "Flip Edge" tool of the Sandbox Plugin to optimize the image matching quality.
