When I first tried your composition I didn't get any meaningful
results. After trying several times, I realized there was a problem
with my MightyMouse.
After I replaced the MM, I can see what you meant to do.
Nice work!
But, I did notice that the large "Desktop Pictures" images (typically
2560x1600 pixels) did not look as good as the originals when scaled up
by your composition.
I fiddled around a bit...
In the Download and Process Images---> Image Resize patch--->Input
Parameters--->Resize Condition--->Only if Image is Bigger
If you set the condition to "Only if Image is Smaller", the images
will scale up properly.
Would love to play with this on a MultiTouch screen & I hope tat Apple
comes out with some larger MultiTouch screen devices... real soon
(while time is to their advantage).
Your composition illustrates how readily a "light table" capability
can be prototyped for, say, Aperture, iPhoto, Pages...
... It would be really fun to use an iPhone/iPodTouch as a MultiTouch
input device and a HD TV connected to AppleTV as the output display.

Hi,
I'm a newbie in QC with background on microsoft tech like
silverlight/wpf and xdk. Charmed by the Surface photo browsing demo
and as a real mac lover I tried to implement a prototype of it on QC.
I looked at some other implementations of it, from iPhone to several
RIA demos (SVG, silverlight etc.), but I figure out that Apple multi
touch approach is far more than let the user put their fingers on
the screen, especially big screen. I believe that big screen multi
touch is very fun and there are lot of stuff you can do in QC using
tools like the Wiimote but I think that asking the user to always
hold on their arms is not the real solution for me.
For operation like zoom and rotate I've planned to use the new
MacBookAir trackpad gesture for pinch, swipe and rotate but in the
view of the fact that first I don't have a MacBookAir and second
gesture SDK doesn't seems to be available at the moment I simulate
the pich effect with the scroll up/down gesture and the rotation
with the scroll left/right gesture of a MacBook regular trackpad.
An interesting side effect of this roundtrip by the way is that it
works even with a mighty mouse, that in some way it also implement a
sort of multi touch experience.
Well the composition in attach is just a prototype and doesn’t
implement all the features of the original demo but there are some
consideration about the development of it that I’d like to share
with you.
As I just said I’m not a expert at all here and this was really my
first experience with this tool but I found extreme advantages from
Quartz Composer. I found it a very high level tool, easier to use
then any other traditional development environment and I believe it
implements a real visual approach on graphic programming. I really
appreciate how it's so easy to reuse graphic components. Actually I
focused only on the script that handle user input and move photos,
all the graphics effects have been just copied from the samples in
the SDK.
It’s amazing how it is so easy and transparent to add complex
animation and graphic filtering. I found outstanding how few lines
of code I had to write to build such a user interface prototype.
I really believe that QC has lot of potential but as a newbie I've
found no book and few stuff on the SDK and on the web helping me to
understand the potential and the right usage of this tool.
I’m investigating the easy integration with Cocoa Bindings,
DashCode, QuickTime and even Safari but my question is if QC is the
right tool to build an application like this one or if it better to
directly code in Cocoa and Quartz2D/OpenGL ? Please review the
prototype and let me know.
Thanks in advance,
jacopo mangiavacchi
