Member Data Documentation

int64_t SoLDMDataAccess::DataInfo::bufferSize

Size of the data tile in bytes.

ErrorValue SoLDMDataAccess::DataInfo::errorFlag

Error indicator.

Use enum ErrorValue. Note that even when errorFlag is CORRECT, bufferSize may be zero meaning no data was returned.

void* SoLDMDataAccess::DataInfo::tileData

Pointer to the data tile, valid until the releaseData() method of SoLDMDataAccess is called or the associated SoVolumeData is destroyed.

SbVec3i32 SoLDMDataAccess::DataInfo::tileDimension

Dimensions of the data tile in voxels.

SoLDMTileID SoLDMDataAccess::DataInfo::tileID

LDM tile ID of the tile that contains the data at tilePosition.

SbBox3i32 SoLDMDataAccess::DataInfo::tilePosition

Position of the data tile in voxel coordinates (min = lower left back corner, max = upper right front corner).
