| GetStringName | (Inherited from SoBase.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| HasDefaultValues | Returns true if all of the object's fields have their default values. |
| IsEvaluating | Returns true if the engine evaluation is in progress. |
| IsNotifyEnabled | Notification is the process of telling interested objects that this object has changed. |
| IsSynchronizable | Gets the ScaleViz synchronizable state of this object. |
| Set | Sets one or more fields in this object to the values specified in the given string, which should be a string in the Open Inventor file format. |
| SetName | (Inherited from SoBase.) |

| regularizationType | The type of regularization used to enforce the smoothness of the mesh. |
| rightBoundaryCondition | The type of boundary conditions for the right boundary. |
| smoothing | A regularization is applied on the fitted mesh in order to smooth it and limit the effect of outliers. |
| thresholdLevel | Defines a range of values that can be considered for the best fit. |
| topBoundaryCondition | The type of boundary conditions for the top boundary. |
| UserData |
Gets or sets the user data to be contained by the field container.

| OnProgress | Event raised while processing is running. |
RemarksThis 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 OIV.ImageViz.Engines.ImageSegmentation.ComputationalGeometry.SoSurfaceFittingApproximation3d.distance. A voxel will be considered as a best fit based on a criterion given by the OIV.ImageViz.Engines.ImageSegmentation.ComputationalGeometry.SoSurfaceFittingApproximation3d.detectionType. A regularization can be applied on the resulting surface to smooth it and limit the effect of outliers.
