Is there a 2d sprite library for webgl?

Question

I am looking to build a 2d game using WebGL. I want the hardware acceleration that WebGL provides and I cannot get this from the 2D canvas context in the canvas tag.

With that said, is there a tutorial on creating 2D sprites using webGL? Or, better yet, is there a 2D sprite library for WebGL? Ideally, I'm looking for something like cocos2d ported to WebGL.

Not surprisingly, all of the demos, tutorials and libraries I have found for WebGL focus on 3D manipulation. Are there any WebGL libraries that support 2D sprites?

Answer 1

I may be mistaken, but I thought that the 2D canvas API was designed in such a way that browsers can make use of hardware acceleration, but they have chosen not to yet. I expect the implementations of canvas 2D to improve dramatically as WebGL progresses.

Answer 2

2D in 3D is extremely easy to do. You just have to place all your objects in a plane and scale your viewport to draw the desired portion of that plane.

In any case, there is approx 10 years 'till you can expect to find WebGL capability in most peoples browsers. With the right methods you can get a long way without using canvas, the trick of using prerendered rotations of your graphics is a must know to any JavaScript game developer, along with "sprite" animations.

The important question is, are you just playing with the tools, or are you making a game that people should be able to play and enjoy?
