Hello,
Thanks very much to you and Troy for enabling me to find this stuff
- Snow was the example I was after.
Im very impressed with the performance of the sample CL particle
system. This stuff is perfect for me as I am not good enough to code
such things from scratch, but when I look at the code I can
understand it & butcher it for my own purposes!
Ive already had fun splicing the Snow sample with the default music
visualisation template.
This leads me to ask a silly question - Will I be shot if I
distribute compositions that contain the particle openCL code from
the snow sample? If so then I need someone to recreate similar
functionality but in a way that can be freely distributed by myself
and others. Any takers? I have some money I could throw someones way
for doing this, but its not a huge amount (equivalent of about £100)
so Im not sure if there will be any takers or whether this offer may
appear insulting.
Cheers

Currently, the only WWDC 09 sample posted is called "Snow". I did
not see it earlier either because searching for [snow] shows you
all samples updated for Snow Leopard, and searching [Quartz
Composer] does not show it either. You need to do a query for
[quartz] and then scan that page for a sample called "Snow". This
will be a good example of generating points using JavaScript and
feeding them into OpenCL to power a particle system.
Here's a direct link:
http://developer.apple.com/mac/library/samplecode/Snow/index.html
There's also a demo of the new Interaction functionality (first
presented at WWDC 2008) :
