Hello All!
I am currently attempting to draw three-dimensional function plots in Pascal,
but am having troubles converting a point with three-dimensional coordinates
into two-dimensional coordinates for display.
What I desire is to specify a Rotation angle and an Elevation angle for the
eye, and then scale the resulting graph to fit within my display. Does
anybody have an algorithm for such a conversion? If not, could someone
point me in the direction of a volume or two on graphic algorithms that could
provide me with the necessary information?
Please E-Mail answers so as to not clutter the Net with bits of code.
Thanks profusely in advance.
(If the .signature doesn't work!)
