SyntaxThe SoLDMDataTransform type exposes the following members.
Methods| Name | Description | |
|---|---|---|
 | Affect | Returns true if the transformation affects the specified region. |
| 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. |
| GetAffectedRegion(Queue) | Obsolete. Returns a list of IJK bounding boxes affected by this transformation. |
| GetAffectedRegion(IListSbBox3i32) | Returns a list of IJK bounding boxes affected by this transformation. |
| 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. |
| 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. |
| 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. |
| ToString |
Converts this SoBase structure to a human readable string.
(Inherited from SoBase.) |
| Touch | Marks an instance as modified, simulating a change to it. |
| TransformFunction | Data transform function. |
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 object defines a transform function to be applied to each LDM tile after it is loaded (returned from the volume reader) but before it is stored in system memory (LDM data cache). This allows you to modify the original data (for example, scaling or filtering) before it is displayed. It can also be used to create multiple data sets in memory from a single data set on disk.
Derive a new class from this one and implement the OIV.LDM.Nodes.SoLDMDataTransform.TransformFunction(OIV.LDM.Nodes.SoDataSet, OIV.Inventor.SbVec3i32, OIV.Inventor.Devices.SoBufferObject, OIV.Inventor.SbBox3i32, System.Int32) method. Create an instance of the new class and set in the dataTransform field of the OIV.LDM.Nodes.SoDataSet node.
Notes:
Applies to all volume data. A data transform can be applied to any type of volume data, not just data loaded from a .ldm format file. Internally all volume data sets are managed by LDM as tiles.
OIV.VolumeViz.Nodes.SoVolumeTransform The OIV.VolumeViz.Nodes.SoVolumeTransform node also allows a transform function to be applied to each LDM tile, but the transform is applied immediately before the tile is loaded onto the graphics board. OIV.VolumeViz.Nodes.SoVolumeTransform does allow the Data Access API to be used in the transform function.
OIV.LDM.Nodes.SoDataCompositor The OIV.LDM.Nodes.SoDataCompositor node allows a transform function to be applied in the special case where multiple volumes should be combined into a single volume.
