SoVRLdmFileBorderReader::SoVRLdmFileBorderReader | ( | ) |
Default Constructor.
|
virtual |
Returns the border flag.
If 0, tiles do not overlap. If not 0, they do. Since OIV 9.0 always returns 0.
Reimplemented from SoLDMReader.
BuildTileMethod SoVRLdmFileBorderReader::getBuildTileMethod | ( | ) |
Return the current method used to build tiles in lower resolution.
|
static |
Returns the type identifier for this class.
|
overridevirtual |
Gets the characteristics (file header) of the data volume.
See SoDataSet::setVolumeData().
You can use the convenience method setFilename() to specify the file location, in which case you will not have to open the file yourself. Then you can use the convenience method getBuffer() to read the header in order to get the requested information.
NOTE: We strongly recommend that readers implement this version of getDataChar, introduced in VolumeViz 5.1, because it uses SbVec3i32 for the volume dimension.
Reimplemented from SoVRLdmFileReader.
Returns the size of a data tile.
Reimplemented from SoLDMReader.

virtual |

Reimplemented from SoVRLdmFileReader.

Return true as this reader is thread safe.

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 SoLDMFileReader). 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.
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 readers (can be used for mapping to a different index scheme). |
Returns a pointer to an allocated buffer containing the data.
Reimplemented from SoLDMReader.
void SoVRLdmFileBorderReader::setBuildTileMethod | ( | BuildTileMethod | method | ) |
Set the method used to build tiles in lower resolution.
Default value is AVERAGE.
|
virtual |
Specifies the path of the file.
Returns 0 for success. Any other return value indicates failure.
