iOS on QC

Has anyone heard anything from Zugakousaku about their iOS experiments with Quartz Composer? I'm greatly interested in this...

I know right? Imagine this in conjunction with Quartz Builder...

Re: iOS on QC

Well, there is no QC on iOS. Unless they somehow got hold of a beta of iOS 6.0? ;)

Most likely they're streaming video to the ipad, so it's actually running on the mac (funny how they show the same comp running, perfectly in sync, no?) Perhaps with touch input from the ipad sent back to the mac? Could be fun, but it'd be pretty limited.

If it's "real"... then how? You'd have to replicate a whole load of stuff from QC on the ipad. It'd be a ton of work. And for what?

That's what I thought when I saw it.

Maybe someone with XCode experience can glean some clues from the full size screen shot? http://twitpic.com/52o368/full

I seem to remember asking him at the time if it was faked or executing QC code on iPad and he said +executing+. Can't find the email maybe i asked on twitter.

Of course even if he is executing code on the iPad, App Store would never allow it to be distributed being non-std frameworks.

Re: iOS on QC

wow this is amazing! The xcode screenshot hints to it being an actual iPad app built against the iOS 4.3 SDK!

Technically this could be possible. A QTZ is simply an XML file. It's very plausible that someone could write a custom QTZ loader, and then replicate the patches with native cocoa and opengl es. The composition seen in the screenshot and video has very straightforward patches (image loaders, sprites, lfo's, interpolators, basic arithmetic etc.) so it's very doable. And technically it should be within the apple submission rules. The QTZ is only data while all the binary still comes from native cocoa / xcode and could be implemented without using private frameworks. (Analogous to the PureData parsers on iOS, like RJDJ).

Potential is huge! This is a pretty impressive development!

Re: iOS on QC

Good points Memo. I assumed a literal but disallowable port of the QC framework, my bad. Whatever it is believe @zuga is legit — v high credibility regards work.
