| SoVolumeData Properties |
The SoVolumeData type exposes the following members.
Properties| Name | Description | |
|---|---|---|
 | allocateResourceOnRender | Indicates if resource allocation is done only on first render traversal or as soon as the node is created. |
| data | Specifies the volume data, including dimensions, data type and number of significant bits. |
| dataRGBA | Contains true if the volume contains RGBA values rather than scalar values. |
| dataSetId | When using multiple OIV.LDM.Nodes.SoDataSet nodes, the OIV.LDM.Nodes.SoDataSet.dataSetId field uniquely identifies each data set used in the compositing. |
| dataTransform | 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. |
| extent | The real size (extent) of the volume in modeling coordinates. |
| fileName | Indicates the file location containing the data set. |
| IsDisposable | ISafeDisposable interface implementation.
(Inherited from SoDisposable.) |
| LDMDataTransformCallback | Obsolete. If set, the user-defined function is called after each tile is loaded, but before it is stored in main memory. |
| ldmResourceParameters | Contains an OIV.LDM.Nodes.SoLDMResourceParameters object which allows you to set LDM resource parameters. |
| Reader | Returns the current data set reader object. |
| texturePrecision | For scalar (non-RGBA) data, specifies the size of voxel values on the GPU in bits. |
| undefinedValue | Data with this value won't be rendered. |
| useCompressedTexture | Controls use of OpenGL lossy texture compression for RGBA data (if available). |
| useExtendedData | If true, VolumeViz stores an additional copy of each loaded tile. |
| usePalettedTexture | 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). |
| UserData |
Gets or sets the user data to be contained by the field container.
(Inherited from SoFieldContainer.) |
| useSharedPalettedTexture | Note: On graphics boards that support programmable shaders, this field is ignored (virtually all graphics boards support programmable shaders). |
| valueInterpretation | Specifies if this dataset corresponds or does not correspond to a segmented image. |
