Member Function Documentation

void Voxel_ColorDS::Destroy ( )

A destructor of the voxel model.

Standard_Byte Voxel_ColorDS::Get ( const Standard_Integer  ix,

)
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.

void Voxel_ColorDS::Set ( const Standard_Integer  ix,
const Standard_Integer  iy,
const Standard_Integer  iz,
const Standard_Byte  data 
)

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).

void Voxel_ColorDS::SetZero ( )

The method sets all values equal to 0 (false) and releases the memory.
