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.) | |
SetSynchronizable | Sets this to be a ScaleViz synchronizable object. | |
SetToDefaults | Sets all fields in this object to their default values. | |

For an introduction to geodesy, see section OIV.ImageViz.Engines.MathematicalMorphology.GeodesicTransformations.
The result of the OIV.ImageViz.Engines.MathematicalMorphology.DistanceMaps.SoGeodesicPropagationProcessing2d Command, applied to a binary image without holes, is a grey level image where each pixel has a grey level value equal to . The following image contains the result of a geodesic propagation on an image to differentiate the various grey level values appearing as stripes or rings. For the largest particle, has a minimum of 36 and then values spread until 70 at the extremities. It means that the shortest distance is 36 and the length of the particle can be considered as equal to 70. For particles close to a disk, the geodesic center is located at the center of the particle, and points with the same grey level value are concentric rings.
The geodesic function has a minimum for each particle which is either a point or a region, named the geodesic center of the particle. The value of this minimum is named the geodesic radius of the particle, as a circle drawn from any of the geodesic center points with such a radius will hit the extremities of the particle.The maximum is reached at points usually located at the extremities of the particles named geodesic extremities. The value of this maximum is named the geodesic diameter and is seldom equal to 2 times the geodesic radius. In the case of a disk, the center is the geodesic center and the diameter is the geodesic diameter.
