Specifies the volume data, including dimensions, data type and number of significant bits.

Contains true if the volume contains RGBA values rather than scalar values.

When using multiple OIV.LDM.Nodes.SoDataSet nodes, the OIV.LDM.Nodes.SoDataSet.dataSetId field uniquely identifies each data set used in the compositing.

If set to an appropriate OIV.LDM.Nodes.SoLDMDataTransform object, the object's transformFunction method is called after each tile is loaded, but before it is stored in main memory.

The real size (extent) of the volume in modeling coordinates.

Indicates the file location containing the data set.

If set, the user-defined function is called after each tile is loaded, but before it is stored in main memory.

Contains an OIV.LDM.Nodes.SoLDMResourceParameters object which allows you to set LDM resource parameters.

If true, VolumeViz stores an additional copy of each loaded tile.

For a volume containing scalar data values, controls whether scalar values (true) or RGBA values (false) are loaded on the GPU (the name is historical).

Note: On graphics boards that support programmable shaders, this field is ignored (virtually all graphics boards support programmable shaders).
