Hi

Good question.  I think they will be sent to a graphics engine, on a different process. Essentially we want to keep ChucK computations where they are, and offload as much graphics as possible to a separate process.
Not sure how this will work in practice...

On the other hand, if we knew what we are doing, it wouldn't be research!

 
Maybe not usefull, but fluxus have a graphic engine implementation (and interface to the scheme language).
Something interesting is, I think, how can be used the concurrency in an spatial domain, compared with the time domine. Objects rather than sounds.

Cheers
