SoVolumeReaderReadTile Method (Int32, SbNativeArrayByte, SbBox3i32)

Note: This API is now obsolete.

Given an index, reads a tile if the data is organized in tiles (for LDM). In the default LDM architecture, the LDM data is based on an octree topology (see SoVRLdmFileReader). The index passed is 0 for the tile of lowest resolution representing the entire volume (octree root node). The index increments linearly going down through the octree.

)

Parameters

index
Type: SystemInt32
buffer
Type: OIV.Inventor.GenericSbNativeArrayByte
tilePosition
Type: OIV.InventorSbBox3i32

Return Value

Type: Boolean
Remarks

Indexing works as follows: Tile 1 is the lower back left corner of the cube. The index increments on X, then Y, and finally Z. So the back tiles are: 3 4 1 2 And the front tiles are: 7 8 5 6 The tiles of full resolution are the leaf tiles. index specifies a fileID, the id of an existing tile (fileID=tileID in a cubical volume). tilePosition specifies the position of the data in the associated volume data of the tile corresponding to the given index. In the default SoVRLdmFileReader, the tilePosition isn't actually used but it is passed as a convenience for customized reader (can be used for mapping to a different index scheme). The data is returned in the allocated buffer.
