cool idea for a sequencer using jit.lcd

checkout this one: http://lab.andre-michelle.com/pulsate awsome, isn’t it?

for some time I’ve been trying to recreate this in Max. unfortunatelly with no luck ;>. So if anyone know how to implement hit test in jit.lcd please let me know. cheers

that is a fantastic synth!! totally addictive and elegant.

Not sure about the hit test stuff, there are probably a bunch of ways to do it, some taking much longer than they need to… though with circles that expand and contract at a given rate, you could probably keep a list of their radii and watch for overlaps. Could be a little tricky though.

you might look into the cosm~ externals from CNMAT, they might not do exactly what you need, but they do handle 3D sound spatialization/ambisonics… amazing. Maybe there would be a way to create the synth using them, as they can manage things like tracking and collision.

Your synth could go to the 3rd dimension, so instead of expanding and contracting circles, they’re spheres… and should you map images and video onto them? Of course you should!!

Ah man, i love this kinda stuff. I guess you could also use box2d for this. I haven’t used it myself but it handles physics and collison-detection.

Did you guys that attachment to run ok? I ran it and it appeared there were some connections missing and it didn’t function as expected.

Same here yes but the max-window didn’t show anything missing?

@seejayjames : thx for the CNMAT suggestion – I’ve found some good math there:)
@FRid : I got box2d but it was too hard for me to get around.

sorry for the wrong attachment.

now I’m few steps further and got something going – two circles ;)
hope this file will work OK..

cheers!

Here is a shot I took at it tonight…

4 circles, but you can easily add as many as you like. Probably better to use poly, but I thought that might be better to wait for adding the synth to it. Has some potential.

Hope this helped…
