here’s my problem – i’ve used the shiva and vishnu objects to generate particles and i want to try and apply the individual particle coordinates (x and y only) to certain parameters in an audio system.

anyways, i cant work out how to read the information i need from the jit.matrix object. i’ve been messing around with jit.peek~ but i’m not too sure if this is the right thing to do.

any help would be appreciated, thanks!

though im still slightly confused about the jit.iter object. say if you’re generating 100 (or any number more than 1 i guess) particles then how does the jit.iter object differentiate between the individual particles when it outputs the numbers?

sorry, im not sure i phrased that right really. oh well!

thanks again

the jit.p.* objects differentiate particles based on particle id, and they store that id in the first plane of the matrix.
so for three particles, it’s something like this:

0 | life0 | x0 | y0 | z0
1 | life1 | x1 | y1 | z1
2 | life2 | x2 | y2 | z2

this is a 5 plane 3×1 matrix. the p objects would actually store it as a 3×2 matrix. the second dimension is the previous values from the previous iteration of the system.

you can retrieve the particle id by using the left most outlet from the unpack.

what i really would like is to be able to track the individual coordinates of say, eight separate particles from their birth to death. is this possible?

many thanks
