Amino 1.0 is released
After several months of work, nestled in between getting webOS 3.0 out the door and prepping the nursery for the pending arrival of my first child, I am happy to announce the release of Amino 1.0. I have been eagerly following the development of HTML 5 Canvas support in the major browsers as well as ensuring the HP TouchPad will have great support for it. Amino is a great way to use the power of Canvas is modern mobile and web applications.
What is Amino?
//setup var runner = new Runner(); runner.setCanvas(document.getElementById('canvas')); //create a rect filled with red and a black 5px border var r = new Rect() .set(10,20,50,50) .setFill("red) .setStroke("black") .setStrokeWidth(5); runner.setRoot(r); //animate r.x from 0 -> 300 over 5.5 seconds, and repeat runner.addAnim(new PropAnim(r, "x", 0, 300, 5.5).setLoop(true)); //kick off the animation runner.start();
See the results on the Amino homepage here
What can it do?
Amino can draw basic shapes (rects, circles, paths) and animate them using properties (width goes from 10 to 20 over 3.2 seconds) and callbacks. It also can buffer images to speed up common operations, manage varying framerates on different devices, and do Photoshop like image filtering (brightness, contrast, adjustment). And finally, Amino supports keyboard and mouse events on nodes within the scene, not just for DOM elements. In short, it's a portable scene graph for making interactive applications. Amino handles the hard work of processing input and scheduling the drawing to ensure a fast consistent framerate.
How about some examples?
I'm glad you asked. I've put together a couple of examples to show the variety of things you could do with Amino.
PlanetRover is a simple multilevel sidescroller game with jumping and collision detection.
Big Fish, Little Fish is a page from a hypothetical children's ebook, showing how text can be enriched with animation, images, and custom fonts.
This LineChart component is a super easy way to render graphical data in the browser with a minimal api.
These examples and more are available on the Amino Gallery Page.
How do I get it? What's the License
Amino is fully open source with the BSD license. You can download the source and binaries from here, or link directly to amino-1.0b.js from here in your app with a script tag.
