2 a parametric alphabet
3 some fun with noise
When I first read the assignment, I thought John meant to add lower case
letters to the alphabet from ps5. Since my alphabet from last time was
a mix of lower and upper case letters (whatever I could muster from two
filled arcs), I decided to create a new representation for my letterforms.
Here I have a very geometric, parametric alphabet, created from vertical
stems, horizontal lines, diagonal stems, semi-circular arcs, pacman arcs,
and circles. A set of parameters (stroke width, cap height, lowercase height,
x-height, cross-bar position, descender position) determine the alphabet.
Each letter is drawn as a function, rather than a list of points.
This allows letter components to join correctly.
Here, I thought about the noise in terms of wave interference.
The stroke width for the alphabet changes with a sine wave. The mid-line
point changes with a different sine wave, determined by the degree.
