Hello everybody , i was reading a paper that describe the software swarm music(Blackwell and Bentley 2002). This software uses 7 dimensional boids instead of 2 or 3 . I was wondering how can i implement this in pd? Is it possible to add more dimensions to the boids2d or boids3d external? how can i do that? how can i implement boids with more dimensions? If its not possible wouldnt be any difference if i use 2 boids3d objects to control 6 audio parameters? would it be the same having 2 boids3d objects controlling 6 parameters and having one boid of 6 six dimentions?
thanks in advance.

I'm not familiar with these externals. If they are implemented similarly to 'msd' externals, you might be able to recompile for any number of dimensions (fixed at compile time) with a simple flag or so.
how can i implement boids with more dimensions?
With a vector representation of the rules for the boids to follow it should be possible to have as many dimensions as you like: for example, checking that a boid can see another boid:
V `dot` P
----------- > -0.5 , where V = view direction, P = boid direction ||V|| ||P||
This equation doesn't specify dimension, so should work for any.

No - because you don't get transfer of energy/vibes/whatever between the two sets of 3 dimensions - they remain disjoint. It's not just about the total number of dimensions, but how they are connected together (at every point in the space).
