public class SoVRLdmFileReader extends SoLDMReader
The default VolumeViz LDM file format is based on an octree topology. The data is stored in tiles of different subsampling resolution.
The first tile in the file represents the entire volume at its lowest resolution and corresponds to the root of the octree. The next 8 tiles represent octants of the entire volume at a lower subsample step. There is another set of 8 tiles for each of these tiles, and so on, until reaching tiles of full resolution.
The tile index starts at 0 for the root and increments linearly into the octree (1 to 8 for octree children, 9 to 16 for children of tile 1, and so on).
The data of a tile is accessed with the readTile function by passing an index and allocated buffer. This function is called by the SoLDMTileManager when it needs to load a tile in main memory.
Note: SoLDMTileManager is declared SoEXTENDER and is intended for advanced users. For details see its header file.
