class ColorDS from Voxel inherits DS from Voxel
---Purpose: A 3D voxel model keeping 4 bits for each voxel (one of 16 colors).

---Purpose: 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.

---Purpose: Initialization of the voxel model.

is redefined virtual;
Destroy(me : in out);
---C++: alias ~
---Purpose: A destructor of the voxel model.
SetZero(me : in out);
---Purpose: The method sets all values equal to 0 (false) and
-- releases the memory.
Set(me : in out;
ix : Integer from Standard;
iy : Integer from Standard;
iz : Integer from Standard;
data : Byte from Standard);
---Purpose: Defines a value for voxel with co-ordinates (ix, iy, iz).
-- Only the first four bits are used!
-- Initial state of the model is so that all voxels have value 0x0000,
-- and this data doesn't occupy memory.
-- Memory for data is allocating during setting non-zero values (0x0101, for example).
Get(me;

---Purpose: Returns the value of voxel with co-ordinates (ix, iy, iz).
