SoSurfaceFittingApproximation3d surface approximation.
This engine adjusts the positions of the vertices in a structured quadrilateral mesh based on "weight" values given in a volume. These values normally represent some features / structures in the volume, e.g. weights could be the distance to the outside of a wall.
The engine will search for a best fit along a direction specified for each vertex (the vertex surface normal by be default) up to a distance defined by the parameter distance. A voxel will be considered as a best fit based on a criterion given by the detectionType. A regularization can be applied on the resulting surface to smooth it and limit the effect of outliers.

| SoSFEnum SoSurfaceFittingApproximation3d::detectionType |
Defines the criterion on which a vertex will be kept as the best fit.
Use enum DetectionType. Default is MAXIMUM.
Definition at line 134 of file SoSurfaceFittingApproximation3d.h.
| SoMFVec3f SoSurfaceFittingApproximation3d::directions |
Defines the search direction for each vertex.
If the field is empty or if its size is different from the input surface number of vertices, the vertex normals are used as directions. Default value is SbVec3f( 0.0f, 0.0f, 0.0f ), so by default vertex normals are computed for the surface.

| SoSFFloat SoSurfaceFittingApproximation3d::smoothing |
A regularization is applied on the fitted mesh in order to smooth it and limit the effect of outliers.
The smoothing factor defines the strength of this regularization. The greater the value is the greater the smoothing will be. A smoothing value of 0 will disable the regularization. Default is 1.
Definition at line 120 of file SoSurfaceFittingApproximation3d.h.
