Re: Quartzcomposer programming in C

Since Objective C is a superset of C, you should be able to run C code in it without any change. The simplest solution is just to make an Objective C project with all of your C files, and then only use Obj C when you need it.

Obj C is *very* easy to learn for those who already know C. I think you will like it.

Thanks,

Hi Folks.

I saw someone else post the same request yesterday, and I wanted to get some clarification on the options.

- We are developing a fairly large app, which as a part of its functionality, needs to be able to open, render and control Quartz Composer compositions (from within our app)
- Its vitally important that we get good dynamic control over the elements of the composition in real time
- We need to write this app in C. The whole of the rest of the code base for this large app is already C.

So, my questions:
1) Is it possible to play Quartz Composer compositions using C (perhaps via QuickTime). If so, how do we discover and control the published inputs
2) If not, what is needed to call the Objective C stuff from C. Our experience with Cocoa is very limited.

We need to determine the best way to add controlled Quartz Composer playback to an app which is basically all C.

Any advice would be appreciated.
