SceneJS Version 2

SceneJS is a lean and fast scene graph framework for WebGL, designed to be a browser interface for model and data visualisation systems.

Verson 2 refocuses SceneJS on it's original goal, which is to render large numbers of articulated objects at the highest frame rate possible while placing the minimum load on JavaScript and the CPU.

Essentially, SceneJS V2 is an optimised list of WebGL calls with a simple scene graph on top. As updates are made to the scene graph, SceneJS rebuilds affected portions of the display list, keeping the list lean and fast in the process.

Some key features:

JSON API
fast
automatic shader generation
GPU state change minimisation
sharable OpenSG-style node cores
multiple scenes in a page
geometry morphing
text
texture animation
render-to-texture
color, specular, glow, transparency and bump mapping
arbitrarily-aligned clipping planes
multi-layered textures
texture atlass support
render-order layers
debugging modes
messaging system
IoC container
and more..

Building

To build SceneJS, you'll need Java and ANT. Then at the same level as build.xml, type:

ant all

Create the "dist" directory, which will contain all the SceneJS libraries, JSDocs and examples.

If you are modifying the source code and testing it with a new example or your own project the following ant tasks which complete in just a couple of seconds may be helpful. These tasks do not clean the dist directory so previously-generated JSDocs will still available

ant package-lib

Create the "dist" directory and populate the lib directory with scenejs.js, scenejs.min.js, and the plugins and utils directories.

ant packge-examples

Create the "dist" directory and populate the lib directory and the examples directory.
