Class for converting volume data sets into the LDM format.
This class converts existing volume data sets into the LDM (Large Data Management) format.
The LDM converter classes provide many powerful features. Information common to all converter classes is documented in SoConverter, including:
You can subclass from SoVolumeConverter to use a custom volume reader, provide a custom subsampling method, etc. A custom volume reader can be used to convert almost any data format into LDM format. To use a custom volume reader, derive a new class from SoVolumeReader and override the getReader() method. To use a custom subsampling method override the sampleTile method. See for example $OIVHOME/examples/source/VolumeViz/Converters/custom/LDMConverterExample.cxx.
