Direct Known Subclasses:

SoVolumeData
```
public abstract class SoDataSet
extends SoNode
```
Data set node. This class specifies the data set and its properties, and also provides utilities for extracting a subset of the data set and for resampling the data set. The data can be read from directly from a file or can be accessed via a user-defined volume reader. This class is the parent class of the VolumeViz data nodes SoVolumeData and SoMeshGeometry. These nodes provide the data for VolumeViz nodes (SoVolumeRender, SoOrthoSlice, SoObliqueSlice, etc.).
The data set can be specified by:
- Setting the fileName field
  This implies that the data set is stored on disk, in one of the file formats for which LDM has a built-in reader. LDM will automatically select a reader based on the file extension, for example ".am" for the AmiraMesh file format.
Calling the setReader() method
This is the most general method because an application can specify one of the standard LDM readers or implement a customized subclass of SoVolumeReader. LDM will get the data set properties (dimensions, size, data type, etc) and access the data through the specified reader object. This allows the application to completely control how, and from where, the data is loaded.

  - FLOAT
```
@Deprecated
public static final int FLOAT
```
    Deprecated. Use SoDataSet.DataTypes.FLOAT instead.
  - dataSetId
```
public final SoSFInt32 dataSetId
```
    When using multiple SoDataSet nodes, the dataSetId field uniquely identifies each data set used in the compositing. It also specifies the OpenGL texture unit in which the textures for this data set will be stored when doing render compositing. It is 1 by default (texture unit 0 is reserved for the color lookup table by default). The number of available texture units depends on your hardware. You can query this number using getMaxNumDataSets.
    Note: The SoDataSetId node can also be used to define dataSetId. If an SoDataSetId node is traversed before the SoDataSet node, the id from the SoDataSetId node is used and this field is ignored.
    
    Since:
    
    Open Inventor 6.0
  - fileName
```
public final SoSFFilePathString fileName
```
    Indicates the file location containing the data set. Default is an empty string. Depending on the file type, the corresponding SoVolumeReader (if it exists) is used.

    The filename extension is not case sensitive.
    Note: SoDataSet and its derived classes (SoVolumeData, etc) do not search the SoInput directory list to find files specified in this field. To check file existence and other properties the SbFileHelper class may be useful.
  - useCompressedTexture
```
public final SoSFBool useCompressedTexture
```
    Controls use of the OpenGL lossy texture compression extension (if available). false means don't use it. Default is true. A significant advantage of compressed textures is that they conserve texture memory space. At the moment, the extension works on RGBA textures only, not on paletted textures. The compression factor is about 5.
  - texturePrecision
```
public final SoSFUShort texturePrecision
```
    Specifies the color index texture storage size in bits. It defines the n first significant bits that will be used for the rendering. The valid values are 0, 8, and 16. When set to 0, LDM chooses the best precision, i.e., the first valid precision greater than or equal to a certain value, which is the number of significant bits if it is defined, or the size of the current data type otherwise. Default is 0.
    
    Since:
    
    Open Inventor 6.0
  - extent
```
public final SoSFBox3f extent
```
    The real size (extent) of the volume in modeling coordinates. Default is -1,-1,-1 to 1,1,1.
    Note this can be used to define a volume with non-uniform voxel spacing. For example, if the volume dimensions (voxels) are 64x64x64, but the voxel spacing in Z is twice the X and Y spacing, then you might specify the volume size as -1 to 1 for X and Y but -2 to 2 for Z.
  - dataTransform
```
public final SoSFLDMDataTransform dataTransform
```
    If set to an appropriate SoLDMDataTransform object, the object's transformFunction method is called after each tile is loaded, but before it is stored in main memory. This allows you to modify the original data (for example, scaling or filtering) before it is displayed. Default is no transform.
    Note: Before Open Inventor 8.0, the data transformFunction was set using the setLDMDataModifier method. That method is now deprecated.
    
    Since:
    
    Open Inventor 8.0
  - allocateResourceOnRender
```
public final SoSFBool allocateResourceOnRender
```
    Indicates if resource allocation is done only on first render traversal or as soon as the node is created. Default is true. It must be set to false if the dataset is not inserted in a scene graph but will be used for data access for example. Otherwise, memory resources will still remain on default value.
  - ldmResourceParameters
```
public final SoSFLDMResourceParameters ldmResourceParameters
```
    Contains an SoLDMResourceParameters object which allows you to set LDM resource parameters.
- Method Detail
  - setLDMDataModifier
```
@Deprecated
public void setLDMDataModifier(SoDataSet.LDMDataModifier transformer)
```
    Deprecated. As of Open Inventor 9.9, should use dataTransform field instead.
    
    This method allows you to modify the original data (for example, attribute calculation) before it's displayed. The modifyData method of the given LDMDataModifier is called after each tile is loaded.
    
    Since:
    
    6.0
  - setReader
```
public void setReader(SoVolumeReader reader)
```
    Calls setReader(reader, false).
  - startEditing
```
public int startEditing()
```
    Initiate an editing transaction.
    Returns true if successful and also returns a unique transaction id. This value is required for finishing the edit transaction (see finishEditing()) and for undo/redo (see undoEditing() and redoEditing()). Multiple transactions may be active at the same time.
  - getLdmDataAccess
```
public SoLDMDataAccess getLdmDataAccess()
```
    Returns a reference to the SoLDMDataAccess object.
    This object can be used to query data from the volume.
  - readTile
```
public void readTile(SoLDMTileID tileID,
                     SoBufferObject buffer,
                     boolean transform)
```
    Copies the specified tile into the provided buffer.
    Applies the data transformation (set in dataTransform field) if transform is true.
  - writeTile
```
public void writeTile(SoLDMTileID tileID,
                      SoBufferObject buffer,
                      SoVolumeWriter writer)
```
    Write the specified tile using the specified writer. No operations are done on buffer (dataTransform or edition), the buffer is written as is. The writer must be initialized and handles must be properly set (see SoVolumeReader.closeAllHandles and SoVolumeWriter.restoreAllHandles), ie. the current reader's handles must be closed, and the specified writer's handles must be opened.
  - finishEditing
```
public boolean finishEditing(int transactionId)
```
    Terminate an editing transaction.
    Returns true if successful. May only be called with a valid transaction id returned by the startEditing() method. On error does nothing. The finish method will schedule a redraw so the correct data is displayed. To commit the edits, in other words to save the edited data back to the data source, call saveEditing().
  - editSubVolume
```
public int editSubVolume(SbBox3i32 subVolume,
                         double value)
```
    Replace the contents of a subvolume with the specified value.
    The subvolume is specified in voxel/cell coordinates. Call startEditing() before calling this method. Returns 0 if successful.
  - editSurfaceShape
```
public int editSurfaceShape(SoNode surfaceShape,
                            float thickness,
                            double value)
```
    Replace all voxels intersecting the polygons or lines defined by the surfaceShape and given thickness with the specified value. surfaceShape is defined in the same 3D space as the dataSet. thickness is defined in voxels. The surfaceShape can be deleted after calling this function.
    Call startEditing() before calling this method. Returns 0 if successful.
    Warning The modification may be postponed until the tiles are really needed. Therefore the surfaceShape node (and children if any) must not be modified until after saveEditing() is called.
  - editTile
```
public int editTile(SoLDMTileID tileId,
                    double value)
```
    Replace the contents of a tile with the specified value.
    Call startEditing() before calling this method. Returns 0 if successful.

public int editTile(SoLDMTileID tileId,
                    SoBufferObject userData)
```
    Replace the contents of a tile with the given data.
    The buffer size (in bytes) must match the tile size (in bytes) exactly. Call startEditing() before calling this method. Returns 0 if successful.
    Warning The modification may be postponed until the tile is really needed. Therefore the contents of the userData buffer must not be modified until after saveEditing() is called.
  - editSubVolume
```
public int editSubVolume(SbBox3i32 subVolume,
                         SoBufferObject userData)
```

```
public static int getMaxNumDataSets()
```
    Returns the maximum number of data sets that can be render composited on the current hardware (essentially the number of texture units - 1).
  - getLdmManagerAccess
```
public SoLDMMediator.LDMManagerAccess getLdmManagerAccess()
```
    Returns a reference to an LDMManagerAccess.
  - numSigBits
```
public int numSigBits()
```
    Returns the number of significant bits.
  - getMinMax
```
public long[] getMinMax()
```
    Returns min and max values of the data set data.
    Returns nullif the requested data is not available (for example, if no data set exists).
    
    NOTE: This method might force LDM to load the entire data set if the volume reader does not respond to the getMinMax query. Normally for an LDM format data set, the min and max values are stored in the LDM header. For a non-LDM data set, if a filename and/or reader have been specified and the data set has not yet been loaded, LDM will load the entire data set to compute the min and max values. For a large data set this may take a long time.
  - getReader
```
public SoVolumeReader getReader()
```
    Returns the current data set reader object.
    The actual type will be a subclass of SoVolumeReader, either one of the predefined subclasses or an application-defined subclass. Returns NULL if no reader is currently being used (for example if setVolumeData() was called).
  - getLDMReader
```
public SoLDMReader getLDMReader()
```
    Returns a pointer to the current data set reader object.
    The actual type will be a subclass of SoVolumeReader, either one of the predefined subclasses or an application-defined subclass. Returns NULL if no reader is currently being used (for example if setVolumeData() was called).
  - setLDMReader
```
public void setLDMReader(SoLDMReader reader)
```
    Sets the LDM volume reader object to use.
    This method allows the data to be read directly from the disk using the specified subclass of SoVolumeReader.
  - setReader
```
public void setReader(SoVolumeReader reader,
                      boolean takeOwnership)
```
    This method allows the data to be read directly from the disk using the specified subclass of SoVolumeReader. If the takeOwnership parameter is false (default), LDM will not delete the specified instance. Otherwise, LDM will automatically delete the specified instance, for example, when the SoDataSet node is deleted. If filename is not set before setting the reader, LDM will display an error message just to warn reader did not open any file yet. LDM still work has expected.
    Note: When using a custom reader, any reader method that changes the volume properties (dimension, size, data type, etc) should notify the SoVolumeData node by calling the reader's touch() method. If this notification is not done, SoDataSet fields, for example SoDataSet.extent, won't be updated correctly.
  - isTimeDependent
```
@Deprecated
public boolean isTimeDependent()
```
    Deprecated. As of Open Inventor 9000 See documentation for more details
    
    Indicates if this data set is time dependent.

  - getDoubleMinMax
```
public double[] getDoubleMinMax()
```
    Returns min and max values of the data set.
    Returns nullif the requested data is not available (for example, if no data set exists).
    
    NOTE: This method might force LDM to load the entire data set if the volume reader does not respond to the getMinMax query. Normally for an LDM format data set, the min and max values are stored in the LDM header. For a non-LDM data set, if a filename and/or reader have been specified and the data set has not yet been loaded, LDM will load the entire data set to compute the min and max values. For a large data set this may take a long time.
  - getDataType
```
public SoDataSet.DataTypes getDataType()
```
    Returns the data type.
  - getNodeFrontManager
```
public SoLDMNodeFrontManager getNodeFrontManager()
```
    Returns a pointer to the LDM node front manager.
  - redoEditing
```
public boolean redoEditing(int transactionId)
```
    Redo all modifications associated with the specified transaction id. Returns true if successful. On error does nothing. May only be called after the specified transaction has been terminated (see finishEditing() method) and undone (see undoEditing() method). Schedules a redraw so the correct data is displayed.
    Note: Redo is no longer available after transactions are saved. After calling saveEditing(), the transaction ids are no longer valid and the modified data is the new reference.
  - hasEditedTile
```
public boolean hasEditedTile()
```
    Returns true if DataSet has edited tiles.
  - undoEditing
```
public boolean undoEditing(int transactionId)
```
    Undo all modifications associated with the specified transaction id. Returns true if successful. On error does nothing. May only be called after the specified transaction has been terminated (see finishEditing() method). Schedules a redraw so the correct data is displayed.
    Note: Undo is no longer available after transactions are saved. After calling saveEditing(), the transaction ids are no longer valid and the modified data is the new reference.
  - editSolidShape
```
public int editSolidShape(SoNode solidShape,
                          double value)
```
    Replace all voxels intersecting the given shape with the specified value. The geometry defined under solidShape must represent a list of closed surfaces otherwise the result is unpredictable. solidShape must not contain any lines or open polyhedrons (polyhedron with shapes). The result is based on the odd-winding rule, so the result is not necessarily the union or the intersection of the closed surfaces. If you want to voxelize lines or single polygons, see also the editSurfaceShape method.
    If the goal is to define a shape which is the results of the intersection/union of multiple closed surfaces, see the SoCSGShape node.
    solidShape is defined in the same 3D space as the dataSet. The solidShape can be deleted after calling this function.
    Call startEditing() before calling this method. Returns 0 if successful.
    Warning The modification may be postponed until the tiles are really needed. Therefore the surfaceShape node (and children if any) must not be modified until after saveEditing() is called.
  - editBoxes
```
public int editBoxes(java.util.Collection<SbVec3i32> boxCenters,
                     int boxSize,
                     double newValue)
```
    Replace all voxels in the region defined by a list of boxes with the specified value. boxCenter and boxSize are defined in ijk (voxel) space.
    Call startEditing() before calling this method. Returns 0 if successful.
