Hi
I am pretty new to graphics but I want to create an iphone/ipad app that does free hand drawing. That is as the finger moves, a path is painted. Where do I start (books, resources, etc)? The stuff I see on apple's docs talk about lines and arcs. These are simple. They talk about bezier curves briefly. Is this what I should be looking into? Should I even be using quartz for this type of drawing since the number of interpolations would be very high (I presume) and thus make this type of drawing quite inefficient?
Thanks
