Constructor & Destructor Documentation

Voxel_OctBoolDS::Voxel_OctBoolDS ( )

An empty constructor.

Voxel_OctBoolDS::Voxel_OctBoolDS ( const Standard_Real  x,
const Standard_Real  y,
const Standard_Real  z,
const Standard_Real  x_len,
const Standard_Real  y_len,
const Standard_Real  z_len,
const Standard_Integer  nb_x,
const Standard_Integer  nb_y,
const Standard_Integer  nb_z 
)

A constructor initializing the voxel model. (x, y, z) - the start point of the box. (x_len, y_len, z_len) - lengths in x, y and z directions along axes of a co-ordinate system. (nb_x, nb_y, nb_z) - number of splits (voxels) along x, y and z directions.

Member Function Documentation

void Voxel_OctBoolDS::Destroy ( )

A destructor of the voxel model.

Standard_Boolean Voxel_OctBoolDS::Get ( const Standard_Integer  ix,
const Standard_Integer  iy,
const Standard_Integer  iz 
) const

Returns the value of voxel with co-ordinates (ix, iy, iz). Warning!: the returned value may not coincide with the value of its 8 sub-voxels. Use the method ::IsSplit() to check whether a voxel has sub-voxels.

Standard_Boolean Voxel_OctBoolDS::Get ( const Standard_Integer  ix,
const Standard_Integer  iy,
const Standard_Integer  iz,
const Standard_Integer  ioct 
) const

Returns the value of a sub-voxel of a voxel with co-ordinates (ix, iy, iz). If the voxel is not split, it returns the value of the voxel. Range of sub-voxels is 0 - 7.

virtual void Voxel_OctBoolDS::Init ( const Standard_Real  x,
const Standard_Real  y,
const Standard_Real  z,
const Standard_Real  x_len,
const Standard_Real  y_len,
const Standard_Real  z_len,
const Standard_Integer  nb_x,
const Standard_Integer  nb_y,
const Standard_Integer  nb_z 
)
virtual

Initialization of the voxel model. (x, y, z) - the start point of the box. (x_len, y_len, z_len) - lengths in x, y and z directions along axes of a co-ordinate system. (nb_x, nb_y, nb_z) - number of splits (voxels) along x, y and z directions.

Reimplemented from Voxel_DS.

Standard_Boolean Voxel_OctBoolDS::IsSplit ( const Standard_Integer  ix,
const Standard_Integer  iy,
const Standard_Integer  iz 
) const

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).

void Voxel_OctBoolDS::Set ( const Standard_Integer  ix,
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.
