Flex for visual prototyping

Digital Humanities, Experiments, Flash, Flex, Interactive Design

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.
