Just a quick note to say hello from Adobe MAX in LA. This is a short preview of a project I’ve been working on with Paul Taylor. At 360|Flex, we showed a demo where TinyTLF was used to layout text respecting a spline boundary. Paul showed scrolling with TinyTLF here at the 360|Flex Unconference. The next natural progression is to have both the text boundary and the scroller be organic; that is, both are based on the same Bezier spline. The scroller itself and the thumb are dynamically rendered in Actionscript. The small image below shows a preview of one test case.
Needless to say, there is a *lot* of math involved ranging from arc-length parameterization to interpolation models to a nonlinear model for scroller thumb interaction. The alpha component is being turned over to Paul for integration into a TinyTLF demo and further testing. Once it’s solid, we will work on a vehicle for distributing the code, which will include at least a white paper on all the math used in the scroller construction.
More to come later!
