function point = gen_specific_point_3D(ranges)
% gen_specific_point - function generates point about which 2D object
% will be rotated.
% <a, b> - specific range for those points on x-axis
% <c, d> - specific range for those points on y-axis
% <e, f> - specific range for those points on z-axis
% point - point which will be returned in specific shape [x, y, z]
