I was going to write two chapters on Core Image, unfortunately, the advanced chapter turned out to be too difficult and contained some bugs (marrying Core Image with Cocos2D can be problematic) so I only ended up writing one. However, I will be posting that stuff here next month. I’ll show you how to use Core Image to apply some cool effect to your games in Cocos2D. And, I’ll tell you where that starts to break down.
However, that one chapter is awesome! In it I show you how to build a complete video recording app that uses Core Image filters to do real time video processing effects. Here’s a video that shows the various filter effects that you can do. (I took this video with the app, all in one take).
Using the project you build in that chapter, it is very easy to add tons of other effects using Core Image.
You should definitely check out the new book, in addition to my Core Image chapter, there are tons of other chapters covering the new APIs that were made available to us devs last week.
