This is one reason why I’m really digging Flex right now. I’m in the design phase with Sharon Daniel on a follow-up project to Public Secrets and we’re talking about dynamically generating a large number of curved forms as part of the design. All well and good, but how do I mock up the curves without drawing a million squiggly lines by hand? Easy—build a little Flex app that lets me set the parameters of the curve and generate as many as I want, then take screenshots and bring them into Photoshop. This is my first app using this many controls, and it only took a couple hours to put together. There’s a lot of ways in which Flex makes building this kind of thing feel as easy as it really should.
The curve is drawn using a cardinal spline algorithm (Update: c-spline source code) I first ported to Lingo back when I was working on Chroma, and then to ActionScript a couple years ago for Mobile Figures. I like it because it’ll run a smooth curve through any number of values without you needing to specify separate control points.
