A javascript helper library for writing interactive WebGL apps.
The library is built around a single core file kangas-core.js
that defines wrapper objects for WebGLRenderingContext,
WebGLShader and WebGLProgram. This core can be used on its own,
and is already useful. However, for convenience the core
functionality is extended in a modular way:
-
kangas.js-- extends the graphics context object defined inkangas-core.js, to include handling of touch/mouse events, cleanup before page unload, and fullscreen requests. -
kangas-transforms.jsandkangas-constants.js-- some 3D math and constants. -
kangas-renderer.js-- an object that manages the animation loop and the vertex and index data. -
kangas-texture.js-- a wrapper object around WebGLTexture; aids in creating textures from various sources (image file, frambuffer attachment, raw pixel data, etc.), and managing texture parameters. -
kangas-noise.js-- generating noise textures: White noise, Worley (cellular) noise, and fractal noise. -
kangas-bumpmap.js-- extendskangas-textureby providing functionality for generating a bumpmap texture from a given input texture. -
shader-source-load-- A web worker script for loading shader files and organizing shader source code for the rest of the application. -
webgl-app.css-- an extremely basic css stylesheet for WebGL apps; mostly for fullscreen applications. -
The library contains a third-party minimized script for building Voronoi diagrams. The script is copyrighted

The library's functionality is accessed through a single global
object (named Kangas by default), which is the constructor for
the graphics context wrapper object, mentioned above.
Examples of WebGL apps using the library are available at http://ido.filin.fi/showcase.html and https://github.com/idofilin/webgl-showcase.
