Drawing arcs
Nov 11th, 2009, 8:28pm  
Hello,

I'm working on a Processing sketch inspired by Donald Knuth's MetaFont to draw letterforms composed of lines and circle segments. I know about arc(), but instead of using Processing's normal line drawing function, I'd like to draw different shapes or images at the different points along the lines or arcs that make up the letterforms.

Is it possible to override arc() somehow to provide my own drawing function? Or, can someone point me to an equation that describes the x, y coordinates along an arc so that I can write my own function?

Thanks in advance,
Andrew

you dont have to override you can just write your own arcs function.
I would probably use http://processing.org/reference/bezier_.html
if you dont want to use Arcs.
But whats wrong with arcs btw ?

You can look into Processing's code... Or take any geometry book, equation of an arc isn't that hard.
Or, even simpler, you can use bezier or curve family, particularly the bezierPoint or curvePoint functions (I think bezier is closer of arc).
