Yes hdcookbook project is a framework that helps seting up a blu-ray java developemnt enevironment (Blu-ray discs use JavaME for building menus based on Xlets kind of Applets, the name comes from JavaTV).
GRIN is the scene graph that comes with hdcookbook framework and it is used for the UI. It is similar to JavaFX but optimized for blu-ray disc players and JavaME (no swing). The core of GRIN is the animation engine (in GWT the animation engine extends Animator). It runs and tries to render a Show file (or more than one). The Show is the Animator client that is called periodically by the Animator's onUpdate() method to paint the next frame of a Show. In GRIN a Show is a set of Segments (only one Segment is active at a time) and a Segment displays a set of Features (the visual elements). The GRIN show file is a simple TXT file that contains all the Show elements and their relations. For example, the demo: http://mosaic.arkasoft.com/GRIN4/ could be a slide show, or a presentation. The GRIN Show file for that demo is: http://pastebin.org/425611 Lines: 74-111 contain the description of each segment in this show. The first segment "Segment0" is triggered by the GWT EntryPoint class. This is why this Show element is exported at line 5. Each Segment can have a set of Features in two states: 'setup' or 'active'. Segment0 is used to setup: F:Scaler and F:Box1.Translator but has to active features. Segment0 will not show any visual elements and once setup is done it will move the Show to Segment1 (line: 80). Segment1 has two active Features (those that are already setup by Segment0) and will display them. Segment1 will then setup F:Scaler and F:Box2.Translator and the Show will be moved to Segment2 after the F:Box2.Transtor is done (see: line 23). And so on, until the Show is moved to Segment3 and back again to Segment0 (see line: 61). About Javelin this is a dead link, I assume this was a project that was using XML instead of TXT for the GRIN Show files. I am still playing with GRIN port to GWT. At least so far one could use it for presentations or games. Kind Regards, George. On 28 Ιούλ, 17:27, Nathan Wells <[email protected]> wrote: > I'm a little confused...
