The closest you'll find I think is the CIVector class.

Of course you could. But it's not uncommon to need a 3 dimensional coordinate, so we were just wondering if there's one built in. Obviously 2 dimensional coordinates are everywhere, and as such the appropriate struct is included in the frameworks. We were thinking that with 3 dimensional graphics becoming more and more common, there might be one built in already.

Hi everyone,

I was asked yesterday if there's a struct in Cocoa that has 3 float members. The person asking me was looking for a struct that could contain a 3 dimensional point (so like a CG- or NSPoint, but with a z member).

My quick searches didn't reveal anything, but I was wondering if any of you knew of one.

Thanks,

Dave

Surely you could define one of your own?
