SyntaxThe PoCellFilter type exposes the following members.
Methods| Name | Description | |
|---|---|---|
 | AcceptCell | Returns true if the cell is accepted. |
| AffectsState | Returns true if a node has an effect on the state during traversal. |
| Callback | (Inherited from PoNode.) |
| Copy | Calls Copy(false). (Inherited from SoNode.) |
| Copy(Boolean) | Creates and returns an exact copy of the node. |
| 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.) |
| Distribute | (Inherited from SoNode.) |
| DoAction | (Overrides PoNodeDoAction(SoAction).) |
| 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. |
| GetAlternateRep | This method is called by actions to allow the node to provide an "alternate representation" when appropriate (typically depending on the action type). |
| GetBoundingBox | (Inherited from PoNode.) |
| 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.) |
| GetMatrix | (Inherited from PoNode.) |
| GetName | Returns the name of an instance. |
| GetPrimitiveCount | (Inherited from PoNode.) |
| GetRenderEngineMode | Returns the supported Render engine mode. |
| GetRenderUnitID | (Inherited from SoNode.) |
| GetStringName | (Inherited from SoBase.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| GLRender | (Inherited from PoNode.) |
| GLRenderBelowPath | (Inherited from SoNode.) |
| GLRenderInPath | (Inherited from SoNode.) |
| GLRenderOffPath | (Inherited from SoNode.) |
| GrabEventsCleanup | (Inherited from SoNode.) |
| GrabEventsSetup | (Inherited from SoNode.) |
| HandleEvent | (Inherited from PoNode.) |
| HasDefaultValues | Returns true if all of the object's fields have their default values. |
| IsBoundingBoxIgnoring | This method is used by getBoundingBox action traversal to know if the current node must be traversed or not, ie the bounding should be ignored. |
| IsNotifyEnabled | Notification is the process of telling interested objects that this object has changed. |
| IsOverride | Returns the state of the override flag. |
| IsSynchronizable | Gets the ScaleViz synchronizable state of this object. |
| Pick | (Inherited from PoNode.) |
| RayPick | (Inherited from SoNode.) |
| Search | (Inherited from PoNode.) |
| 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.) |
| SetOverride | Turns the override flag on or off. |
| SetSynchronizable | Sets this to be a ScaleViz synchronizable object. |
| SetToDefaults | Sets all fields in this object to their default values. |
| ToString |
Converts this SoBase structure to a human readable string.
(Inherited from SoBase.) |
| Touch | Marks an instance as modified, simulating a change to it. |
| Write | (Overrides PoNodeWrite(SoWriteAction).) |
Properties| Name | Description | |
|---|---|---|
 | IsDisposable | ISafeDisposable interface implementation.
(Inherited from SoDisposable.) |
| UserData |
Gets or sets the user data to be contained by the field container.
(Inherited from SoFieldContainer.) |
RemarksThis abstract class specifies the interface used to filter cells. Filtering cells is a way to specify which cells are used to build the mesh representation. When the method OIV.MeshViz.Nodes.PoCellFilter.AcceptCell(System.Int32, System.Single) returns false, this cell is not taken into account by the representation. It is as if the mesh did not contain this cell.
In order to define a custom cell filter, you must create a class derived from this class. The custom cell filter can be based either on a cell's index or its value. The data set used to check if OIV.MeshViz.Nodes.PoCellFilter.AcceptCell(System.Int32, System.Single) returns true or false is the current data set during the traversal selected by the field OIV.MeshViz.Data.PoMesh.valuesIndexForCellFilter.
WARNING: At this time, the classes inherited from OIV.MeshViz.Data.PoMesh2D ignore the cell filter.
