QBasic/3D Graphics

Simple 3D Box
3 Dimension or 3D graphics in Qbasic is nothing, but including an additional 'z' axis and to extend the 2 dimensional structure along that axis. This can be achieved by drawing a box, or the structure you want, each time at a new x and y position. It is quite like animation, except, we do not erase the structure after it being drawn, and there is no need of any intermediate pause. You can better understand by looking at the 3d box program given below.
