748.0. "Blanking on 3-D plots." by CSC32::RODAS () Tue Aug 11 1987 10:49

    In an attempt to re-write was has been written, no doubt, a thousand
    times before, I am looking for an alogrythm to do blanking on a
    3-D plotting routine.  I.E. How to determine which point on a plot
    would not be seen given some projection.  I can determine whether
    a point can be seen, but what is nessary is to calculate the
    intersection between the horizon on the plot and the diminishing
    line. 
    
    				Thanks for the help.
