<br />
This module can be used as an alternative to ModelMaker to generate a smooth triangulated surface of a segmented label with improved (in the opinion of the author of this module) control over the number of triangles in the output surface, as well as improved visual appearance of the result. In the example below, the Marching Cubes output has 18750 triangles (blue), ModelMaker with 0.5 smoothing and 0.5 decimation generates 11173 triangles, (red) and the output of QuadEdgeSurfaceMesher (yellow) contains 1606 triangles. The result produced by ModelMaker with decimation setting set to 0.99 (a parameter similar to the decimation constant of the module being presented) produces triangulation that looks too embarrassing to show here.<br />

<br />
This module was motivated by the need to generate smooth compact surface triangulations for prostate MRI images.<br />
<br />
The module operates by applying Marching Cubes algorithm to the input segmentation, and then uses the ITK filters implementing the approach described in [1]. Currently, the module does not support multiple labels.<br />
