Returns true if the voxel is split into 8 sub-voxels.
| void Voxel_OctBoolDS::OptimizeMemory | ( | ) |
The method searches voxels with equal-value of sub-voxels and removes them (remaining the value for the voxel).
| void Voxel_OctBoolDS::Set | ( | const Standard_Integer | ix, |
| const Standard_Integer | iy, | ||
| const Standard_Integer | iz, | ||
| const Standard_Boolean | data | ||
| ) |
Defines a value for voxel with co-ordinates (ix, iy, iz). If the voxel is split into 8 sub-voxels, the split disappears. Initial state of the model is so that all voxels have value 0 (false), and this data doesn't occupy memory. Memory for data is allocating during setting non-zero values (true).

| const Standard_Integer | iy, | ||
| const Standard_Integer | iz, | ||
| const Standard_Integer | ioct, | ||
| const Standard_Boolean | data | ||
| ) |
Defines a value for a sub-voxel of a voxel with co-ordinates (ix, iy, iz). If the voxel is not split into 8 sub-voxels yet, this method splits the voxel. Range of sub-voxels is 0 - 7.
| void Voxel_OctBoolDS::SetZero | ( | ) |
The method sets all values equal to 0 (false) and releases the memory.
