Member Data Documentation

◆ bufferDimension

SbVec3i32 SoLDMDataAccess::DataInfoBox::bufferDimension

Dimensions of the 3D data (in voxels).

It depends on the resolution. It is equal to the subvolume if resolution = 0.

Definition at line 343 of file SoLDMDataAccess.h.

◆ bufferSize

int64_t SoLDMDataAccess::DataInfoBox::bufferSize

Size of the requested data in bytes.

Used by the application to allocate buffer.

Definition at line 339 of file SoLDMDataAccess.h.

◆ errorFlag

ErrorValue SoLDMDataAccess::DataInfoBox::errorFlag

Error indicator.

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