Hello, I'm almost a newbye to Pure-Data even if I had some experience
with MAX/MSP. I've got experience in building systems for real-time
processing of video (live or movies) in order to generate data for
music/sound synthesis. I'm looking at writing PD externals to do that.
I'd like to know if it is possible (and how) to add a new datatype to
PD, ore, some advice on how to implement my ideas.
Reading the documentation I've seen that there are very few datatypes:
number, symbol, pointer and audio buffers. Given that I'm just beginning
to tackle the problem may be I'm asking some FAQ, anyway...
I can't understand what is the pointer datatype.
A symbol seems to be "just" a string. Can I add a value a pointer to a
It is possible to build something as audio buffers (image data type, or
multidimensional array)? Does that require modifications to PD?
The system I'm working on, allows to create a chain of processing on
images, then when the system begins to run there is an init phase where
each element of the processing chain is told what kind of images it will
receive, it initializes itself and its internal buffers, and then starts
working everytime it receives data. I think that it is more or less what
happens with the audio chain in PD.
Framestein has a different approach given what I've seen.
Something similar seems to be GridFlow, but I'm having a hard time
trying to understand its inner workings.
Well if somebody can give me some pointer to start think about... thanks
