I'm doing some research on how Starling could help us to bring our Goalscape software (http://www.goalscape.com) to mobile devices with fast GPU accelerated graphics.
Goalscape view is based on the pie-like component which consists of the central circle and many arcs around it which represent goals with subgoals that might be dynamically resized to display goal's importance (see http://www.goalscape.com/sites/all/themes/goalscape/i/importance.gif ) or partially filled to display goal's progress (see http://www.goalscape.com/sites/all/themes/goalscape/i/progress.gif ).
Currently we're using classic Flash DisplayList with its Drawing API. So I was not much interested to take a look at Starling without any support for drawing API. But when Starling-Extension-Graphics (https://github.com/unwrong/Starling-Extension-Graphics) occurred it immediately got my attention so I decided to dive into the Starling framework and the Graphics extension.
I'm not too much familiar with Stage3D graphics but I understand it's pretty complex behind the scenes where Starling really helps. After checking Graphics extension for Starling I found out there are some primitives which can draw basic shapes very easily. And it seems there is even some NGon primitive which can be used to draw arcs out-of-the-box! But I was not yet able to fully understand how this can be used to draw filled arcs with stroke.
So please, could somebody help me out to understand and/or outline any feasible approach how I could draw arcs with some fill and stroke using Graphics extension for Starling?
