Hi dear List
I have a question regarding my Wiimote-OSC experiments.
The wiimote data gets into PD via OSC, either through OSculator or
through a linuxbox running the wiimote external.
So i have problems computing really really fast movements from the
wiimote and i would like to ask if somebody knows about the speed
of messages, be it in OSC, PD or Osculator
1) What do you think is a reasonable message-rate for fast motion-
data ? I have the impression i need to slow down the data (with
speedlim, pipe or resample) to be able to process it
properly - any experience with that or recommendations ?
Pd can handle all of the data that the wiiremote sends, that is not a
problem, unless you are on a machine that is 300MHz or less, then it
might start to be too much.
2) What would you consider the bottleneck ?
Probably in the transmission rate and polling rate of bluetooth.
3) Could it be an advantage to transform incoming OSC-messages into
a signal ? instead of dealing with floats ?
I doubt it.
The idea behind it is to combine x-y IR Data from the wii with the
accelleration data (Mapping accelleration to velocity, but catch
the note from the IR-Position)
Did anybody find a good solution for that ?
I'll bet there is code that does that already, but probably not in
Pd. For example, in one of Johnny Chung Lee's projects. You could
either grab some C code and make an external, or translate the code
into Pd.
