I don't want to be negative but its not that hard. Its not a three
dinensional
problem but a 2-dimensional problem.

I do believe that the person said x,y,z, which means that distance from 0,0,0
would count. That makes it 3-D. Though of course the display itself might be
2-d or the person might have a new sort of display in mind that shows true
depth as well as width and height.
