Split sharp polygon mesh edges with a large feature angle between the adjacent cells.
Split sharp manifold edges where the feature angle between the adjacent polygonal cells are larger than a threshold value. The feature angle is the angle between the normals of the two polygons. Two polygons on the same plane have a feature angle of 0. Perpendicular polygons have a feature angle of 90 degrees.
When an edge is split, it adds a new point to the coordinates and updates the connectivity of an adjacent surface. For example, consider two adjacent triangles (0,1,2) and (2,1,3) where edge (1,2) needs to be split. Two new points 4 (duplication of point 1) and 5 (duplication of point 2) would be added and the later triangle's connectivity would be changed to (5,4,3). By default, all old point's fields would be copied to the new point.
Note that "split" edges do not have space added between them. They are still adjacent visually, but the topology becomes disconnectered there. Splitting sharp edges is most useful to duplicate normal shading vectors to make a sharp shading effect.

Specify the feature angle threshold to split on.
The feature angle is the angle between the normals of the two polygons. Two polygons on the same plane have a feature angle of 0. Perpendicular polygons have a feature angle of 90 degrees.
Any edge with a feature angle larger than this threshold will be split. The feature angle is specified in degrees. The default value is 30 degrees.
