Stereogram drawing of mine workings system by means of microcomputer

Stereogram of mining workings system has been drawn conventional by free-hand drawing or special device, Such as affinigraph, axonome-tergraph in the past.
This paper deales with derivation of mathmatical model as well as programming. In addition the principle and drawing procedure are also studied by means of microcomputer and x-y plotter.
This new method has the following advantages, high efficiency of drawing; high accuracy and free selection of projection parameters, so as to obtain optimazal stereogram.
