ImageVoxel* operator[](int i) const

get line voxel operator

Returns:

desired voxel or 0 if voxel index exceed segment length

Parameters:

i - voxel index (0 for line starting point, > 0 for voxels in direction and < 0 for voxels in -direction

ImageVoxel* getVoxel(int i) const

return a voxel given its index

Returns:

desired voxel or 0 if voxel index exceed segment length

Parameters:
