Achieving this kind of anti-aliasing?
Dec 30th, 2008, 11:41am  
Hello all,

Here is one of my all time favorite processing works:
http://incubator.quasimondo.com/processing/ornamism.php
http://incubator.quasimondo.com/processing/ornamism2.php

But the source is not provided unfortunately. Does anyone have an idea how he achieves such smooth curves and delicate lines in a processing program?

Its also demonstrated here:
http://incubator.quasimondo.com/processing/beziers_ballet.php

and Mr. Klingemann says here that:

"From a technical point of view I'd say that the smoothness of the curves is worth mentioning. That is indeed some haute-couture antialiasing - not the regular stuff that comes with the box."

Any ideas?

I can only guess, as Mario's works are always technically stunning, but...  I suspect he's manually rendering the beziers - see bezierPoint() for how to walk along a bezier.  Then plotting them with subpixel sampling  - where if you need to plot at [1.4,2.7] for example, you simulate that float coordinate by plotting to the four (or 9, or 16, or...) neighboring integer pixels by dividing up the alpha as a ratio of coverage from the floating point pixel center, producing anitaliased pixels.  just a guess, hth
