Aren't gerber files used for PCB design? I remember my brother
mentioning them when he studied OrCAD in school. What I am talking
about is a Fanuc 3C CNC using a Fanuc 500 interpolator and no
high-level FAPT. My brother wrote a program that interprets the Fanuc
500 command script and interpolates the curves thus described, and I
added an export to POV prisms... but it is sloooow (imagine a
cubic_spline prism with 1500 control points!) Since the CNC is really
old, it only uses linear and circular interpolation, so in terms of
POV objects the output can be represented as linear_spline prisms and
pie slices of cylinders. The math to do this evades me, though. Any
help, anyone?
