Animating a path using processing js

[gatapia]

Hi,

I'm currently reviewing a few technologies for a product I want to
build. As such my knowledge of processing.js is limited to 30 minutes
of looking at the web site and playing with the online IDE. Before I
invest more time I just wanted to get the opinions of the serious
users as to wether this technology will meet my needs. Basically what
I am looking for is something that will allow me to animate a path
through vertices at given points in time. I.e. to do something like:

beginShape();
curveVertex(50, 50);
curveVertex(50, 50); // I would like to add a time point here. I.e
1000ms
curveVertex(200, 50); // 2000 ms
curveVertex(200, 200); // 3000 ms
curveVertex(50, 200);
curveVertex(50, 200); // 4000 ms
endShape();

However I would like to assign time points to the vertices and then
animate this path (smoothly, hence interpolating points). Actually I
would like to animate up to 100 of these paths concurrently (each a
different colour).

I'm very excited about the possibility of using processing.js as
having a smooth path through given vertices is something I have been
after for a considerable time so hopefully the animation component can
be done somehow.

Thanks for any help

If you use an irc client to connect to irc.mozilla.org/processing.js you
can find mql_ who will show you how to use his easing plugin for
Processing.js. This would allow you to animate along your curve in some
really cool ways.

Thanks Alistair,

I ended rolling up my own code. This allowed me to keep my library
dependencies down and the code was pretty straight forward (mainly
ported from a java open source project). However I then found that
the visual impact did not justify the performance degradation.

However I do wish I had started using processing.js from the beginning
looks like it would have made my life a lot easier.

Thanks for the help
