1. Do any plotters exist with a mechanism for moving the pen in a smooth
line rather than across a grid of discrete locations? The pen still makes
a relatively smooth movement, but this is simply a desirable artifact.
(I was exposed to plotters for the first time, maybe in 1982 or 83 as a 9
or 10 year old when my Dad brought home a Sharp computer with a plotter
like this one: https://www.youtube.com/watch?v=CVkkii15TLo I found it
fascinating but noticed the pen and platen were still moving in discrete
2. In raster displays, lines look smooth, but I'd guess the line is still
being created with many discrete movements, and they blend together for a
similar reason as the pen on a plotter does - the electron beam cannot
change directly quickly enough to make such tiny jagged edges. Do raster
displays exist which can accomplish an actual straight line?
3. Finally, I think this has interesting applications for 3d Printers.
4. I have no idea how a CDC machine accomplishes curves, but I suppose when
you have a lathe or similar tool capable of smoothing edges it isn't
