Detailed Description

Information about returned data when directly accessing the data rather than copying the data.

Used with the SoLDMDataAccess::getData(int, const SbVec3i32&) method.

Member Data Documentation

◆ bufferSize

int64_t SoLDMDataAccess::DataInfo::bufferSize

Size of the data tile in bytes.

Definition at line 505 of file SoLDMDataAccess.h.

◆ errorFlag

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.

Definition at line 496 of file SoLDMDataAccess.h.

◆ tileData

void* SoLDMDataAccess::DataInfo::tileData

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

Definition at line 510 of file SoLDMDataAccess.h.

◆ tileDimension

SbVec3i32 SoLDMDataAccess::DataInfo::tileDimension

Dimensions of the data tile in voxels.

Definition at line 500 of file SoLDMDataAccess.h.

◆ tileID

SoLDMTileID SoLDMDataAccess::DataInfo::tileID

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

Definition at line 498 of file SoLDMDataAccess.h.

◆ tilePosition

SbBox3i32 SoLDMDataAccess::DataInfo::tilePosition

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

Definition at line 503 of file SoLDMDataAccess.h.
