The new Core Image filter in Quartz Composer 3.0 is loverly.
Using multiple Filter and Math patches a la QC 2.1.
Combining the two filter functions and processing input splitters inside the new Core Image Filter patch, using the Edit Filter Function option.
The only potential downside is that, with everything tucked away inside the one Patch, it becomes much less easy to trace the signal flow and see what’s going on at a glance.
It’s a trade off I’m happy to make though, for the sake of a tidier layout and less cable-spaghetti!
I’m going to try to resist the temptation to go back through all my old Compositions and retrofit them with this new feature…
