jitter and poly~

September 15, 2008 | 8:09 pm

I’ve come across references to poly~ being used with jitter on several occasions and my interest has been peaked. Is poly~ being used to handle msp information that is later passed to jitter objects or is there a way to use poly~ like jit.gl.multiples? Does anyone have any example patches they’d be willing to share?

there’s not much to it.
poly~ is just really useful for managing multiple instances of some abstraction, from one object box.

check out the poly-for-movies patch in the jitter examples.
i remember finding that patch a little daunting at first, but it’s worth it to figure out what’s going on in there.

in the past i’ve used poly~ with the boids object, because i needed more control then gl.multiple allowed. however, gl.multiple will generally be faster for multiple instances of gl geometry.

search the forum, i’m pretty sure there’s more examples out there.

There’s one at http://2uptech.com/patches.html .

Think of poly~ as a for loop. One example of use could be as a
texture delay line where each instance of in poly~ hold a texture that
can be indexed by it’s poly id.

question: if poly~ is used as in the PolyForMovies example, do the jit.qt.movies get distributed to multiple processors? That would be great to take advantage of dual cores (and more…)
