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?
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.
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?
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).
