 Methods
Methods| Name | Description | |
|---|---|---|
|  | AbortEvaluate | Abort current processing as soon as possible. | 
|  | Copy | Creates and returns an exact copy of the engine. | 
|  | CopyFieldValues(SoFieldContainer) | Calls CopyFieldValues(fc, false).(Inherited from SoFieldContainer.) | 
|  | CopyFieldValues(SoFieldContainer, Boolean) | Copies the contents of fc's fields into this object's fields. | 
|  | Dispose |  
Releases all resources used by SoDisposable.
(Inherited from SoDisposable.) | 
|  | EnableNotify | Notification at this Field Container is enabled (if flag == true) or disabled (if flag == false). | 
|  | Equals | Determines whether the specified Object is equal to the current Object.(Inherited from Object.) | 
|  | FieldsAreEqual | Returns true if this object's fields are exactly equal to fc's fields. | 
|  | Get | Returns the values of the fields of this object in the Open Inventor ASCII file format in the given string. | 
|  | GetAllFields | Returns a list of fields, including the eventIn's and eventOut's. | 
|  | GetEventIn | Returns a the eventIn with the given name. | 
|  | GetEventOut | Returns the eventOut with the given name. | 
|  | GetField | Returns a the field of this object whose name is fieldName. | 
|  | GetFieldName | Returns the name of the given field in the fieldName argument. | 
|  | GetFields | Appends references to all of this object's fields to resultList, and returns the number of fields appended. | 
|  | GetHashCode | 
Overrides GetHashCode().
(Inherited from SoNetBase.) | 
|  | GetName | Returns the name of an instance. | 
|  | GetOutput | Returns a reference to the engine output with the given name. | 
|  | GetOutputName | Returns (in outputName) the name of the engine output (output). | 
|  | GetOutputs | Returns a list of outputs in this engine. | 
|  | 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. | 
|  | StartEvaluate | Evaluate engine and dependencies in another thread without blocking the current one. | 
|  | ToString | 
Converts this SoBase structure to a human readable string.
(Inherited from SoBase.) | 
|  | Touch | Marks an instance as modified, simulating a change to it. | 
|  | WaitEvaluate | Wait for the end of engine evaluation. | 
 Properties
Properties| Name | Description | |
|---|---|---|
|  | inSymmetricMatrixImage | A matrix image containing symmetric 2x2 matrices. | 
|  | IsDisposable | ISafeDisposable interface implementation.
(Inherited from SoDisposable.) | 
|  | outEigenValuesImage | Eigenvalues image. | 
|  | outEigenVector1Image | Eigenvector image containing the largest eigen value. | 
|  | outEigenVector2Image | Eigenvector image containing the smallest eigen value. | 
|  | outputSelection | Enable computation of selected outputs. | 
|  | UserData | 
Gets or sets the user data to be contained by the field container.
(Inherited from SoFieldContainer.) | 
 Events
Events| Name | Description | |
|---|---|---|
|  | OnBegin | Event raised when the processing begins. | 
|  | OnEnd | Event raised when processing ends and the result is available. | 
|  | OnProgress | Event raised while processing is running. | 
 Remarks
RemarksThe input image must have three channels, where each channel contains one of the unique components of a 2x2 symmetric matrix. (The redundant fourth component is not necessary.) This engine creates output images containing the eigenvectors and/or eigenvalues of the input matrix image.
Let  be the matrix at position
