The OpenLaszlo application below demonstrates animation along a line, a quadratic Bezier, and a cubic Bezier (the top three paths). It also demonstrates (the bottom path) animation along a path composed of multiple segments.

Drag the slider back and forth to display the point on each path at t=slider.value/100, or click the “Animate” button to animate t from 0 to 1.

I wrote this in order to animate the state markers along the edges of the graph in reAnimator. The GraphViz dot tool, which I’m using for graph layout, generates cubic beziers, so I had to write code to render and evaluate them.

JSON for OpenLaszlo is a JSON library for OpenLaszlo.

I wrote this in order to implement my regular expression visualizer.

There’s a live example below. Clicking on a button requests some JSON text from the server and parses it on the client. The source code to the example is here.

(When it runs off my web site, the debugger in the example displays a warning about not being able to connect to the LPS server. This means that the debugger can’t evaluate expressions, as it could if you were running it off the SDK. I’m just using the debugger here to print inspectable representations of the JSON parse results, and the warning doesn’t affect this.)
