In processing theres a library called glgraphics that allows to use vertex arrays,this allow to calculate vertices in the gpu and it is very fast, i can draw up to 80 000 vertices in my computer.
Is it possible something like this in pd? Is it possible to access to vertex arrays commands from pure opengls from gem?
any idea?

hello,
the repeat/gemlist trick is very fast. it can be used to render lot's more point in real time. (try pmpd example 57 : 2000 points are rendered at 50 fps on my computer with no problem)
ok, good to know. by the way: the examples in pd-ext go only until 51, but i found the others (not there: drpichon.free.fr/pmpd/ google top result) but http://www.chnry.net/ch/?081-pmpd
i suspect that the bottleneck is the list parsing.
i see.
one trick to speed this is to put the list in a table, and use tabread to access the data.
to you know how tables compare to iemmatrix? the advantage of a matrice would be that i can get a whole row at once.
(i did not have a look a the patch, so i may be wrong).
i'll try.
thanks cyrille!

look at the gemvertexbuffer object. it's 1 year old, so with a bit of luck it should be included in latest pd-extended. cheers c

Ages ago I created a set of vertex_ objects that does exactly this. It was too hard to use most of the objects and shaders more or less replaced a lot of the functions anyway. There is a vertex_tab_read that would allow uploading of table data to the GPU.
The other option is to use the tables as textures.

FxRxB! (Feed the Radio Back!) is an experimental collaborative piece
for radio, in which the composer depends on the audience for the
continuity of the piece. Asking the participants to record the program
with an "open mic" in the environment they are in, using their
creativity to the recording techniques, and then send the recording back
to radio. Each program will be composed by the mixing and manipulation
of recordings submitted by the public. This process is repeated weekly,
accumulating these recordings and re-recordings of listeners.This
program is part of the installation mobile-radio created by the artists
Knut Aufermann and Sarah Washington presented at the 30th Bienal of São
Paulo,for more info:http://mobile-radio.net/

RECORDING TECHNIQUE:
After the recordings and the participation at mobile-radio at the
Bienal, a cd of the work will be released, which will include the names
and the requested information of all participants.
how to participate:
record the show live broadcasted by http://mobile-radio.net/, or any
time from www.soundcloud.com/feedtheradioback with an "open mic" in your own environment using any sound recording technique, and then return it to us using yousendit or upload it to our soundcloud page.
