I'd like to make an incremental version of a drawing, i.e.
when displayed it starts of with just a line and gradually
adds more lines, points, color fill-ins etc, which one can
then display as an animation.
I've thought of this approach:
1. Make a Metapost drawing of each stage, with the visible parts
in black and the not-yet visible parts white. This is the
same drawing each time with only the colors varying so that
there is no problem about superimposing frames of different size.
2. Import the Postscript files into GIMP and get it to make them
into an animated GIF.
1. If you straight off know amuch better way, please tell me.
2. For stage 1, is there a way in which I can implement the
following algorithm in Metapost?
a. Draw everything in white
b. for k=1 to n, draw k-th stage in black and export current
version of the drawing as postscript.
