Smoothes the triangle mesh and reduces interferences
This is especially useful for the removal of noise and defects from Scan data as well as for the
smoothing of organic models. In case of technical CAD data, which has usually intended sharp
edges, these edges will also be rounded, if the smoothing values are too high. Consequently,
smaller values should be used as well as the maximum angle deviation should be defined for
technical CAD data in principle.
The smoothing function systematically displaces individual triangle points in order to smooth the
triangle mesh. This displacement depends on the adjacent triangles as well as on the selected
smoothing factor.
A smoothing pass displaces only single points depending on their surrounding area. The impact
of this displacement on the neighboring points will then be included in the following smoothing
passes.
The quality of the smoothing depends on the resolution as well as on the structure of the
triangle mesh. Basically, a higher resolution and a uniform triangle structure produce a better
smoothing result. If the surface resolution is very rough or if the triangle mesh contains many
very small or longish triangles, it is recommended to implement a subdivision of the existing
triangles previous to smoothing.
HINT: In order to enhance the smoothing effect, it is recommended not to set the smoothing
factor too high, but to vary the number of smoothing passes instead
INFO: If individual solids or surfaces are marked, the smoothing function is only applied to the
selected objects.

Preset for data type
Different presets for the differentiation of scan and CAD data can be selected here. This allows
an independent definition and application of standard parameters.
