Defines the settings for the selection of surface areas
By changing the surface options you can influence the surface detection. The selection of proper
settings depends on the geometrical characteristics of the model.
Considering the defined surface options, a surface is generated beginning with a start triangle
(reference triangle). To achieve this, the neighbours of the triangles already contained in the
surface area are tested recursively. If necessary they are added to the surface.

Surface definition
Plane distance: The distance between the planes is used as the criterion for checking the
neighbour triangles of the surface.
Curvature angle: The angel between a plane and its neighbour triangle is used as the test
criterion.
Compare only with reference triangle: If this option is enabled, neighbour triangles are only
compared to the starting triangle. Otherwise, two triangles that are directly in contact are
compared. One of these triangles has to be contained in the surface, the other has to be a
neighbour.
