PureData - floaty wiggly orb

a project i did for my digital signal processing class showing how lowpass filters can be used to imply momentum. if you'd like part or all of my code, drop me a message.

it doesn't do a whole lot, you'll get the just of it after the first 30 seconds. i probably let it go too long.

plz tell me the details of DSP,iwant to learn,and tell me its usage also,and tell me how did u do that

[vynl]

DSP = Digital Signal Processing. it's used mostly for changing sounds (adding reverb or echo, for example).

it'll probably take a few weeks to wrap your head around, but if you've got the time, download PureData from puredata[dot]info

all the graphics environment looks like gem, but in fact, I may think that you are using pdpp (or anything close to this - you know what I am referring, the physics package of pd) to send numbers from pd to processing by p5 (or something like this)

[vynl]

i didn't know PD had a physics package. i'll have to check that out.

but actually, all the movements are lowpassed white noise. 3 channels (X Y Z) for the center sphere, and then they're lowpassed further independently for the orbiting.. uh.. things.

[vynl]

it is GEM.

looks cool. i'm curious how this lowpass filter idea works. can you send me the patches? cheers

[andybient]

hi vynl,

please let me know your patches, that's really interesting stuff...

thanks, andy

screw u

Hey Vynl,

Nice!

I am working on project in PD using boids algorithm. Did you use gemOrb with a spaceOrb controller to move your orb? I would love to see your patch if possible. nice work!

thnx.

Hey man, that's really nice!

Any chance of seeing the source file? I'm trying to do something with PD similar to the 3d object manipulation (tho' not with the DSP bits) and could do with some tips! :-)
