The default constructor technique is getting dirty, forcing us into inefficiencies, such as with ID registration:

SceneJS.Node = function() {
    this._nodeTyp...

Provide the option to create scenes from real JSON, ie. the purely declarative stuff without any function calls in it.

Each event is to be received at listeners as the complete, on which is available the name and event source URL:

SceneJS.node({ sid: "left-green-sphere",

This is an awesome use case for dynamic callbacks - worthy of a demonstration:

SceneJS.material(
    function(data) {

WebGLFloatArray and WebGLUnsignedShortArray have been replaced by the new Float32Array and Uint16Array respectively -https://cvs.khronos.org/svn/repos/registry/...

Add Node#addNodes([SceneJS.Node]) - useful for asset server's kd-tree server, which often needs to push multiple new child nodes to client BoundingBoxes

Signature for createTexture changed a while back - http://blog.tojicode.com/2010/07/obsolete-teximage2d-wha.html

Fixed by using new event management for picking also: https://xeolabs.lighthouseapp.com/projects/50643-scenejs/tickets/14...

Support the firing of events up the scene graph at render time, as shown below.

Basic Case

SceneJS has a two-pass event handling model: on the first traversal, ...

When a child node has been removed from a parent, store it on a "ophan" map until it has been attached to another parent. If a scene traversal is done while the...

Provide a Node#getID method, plus SceneJS#getNode method to find them individually. Node IDs will be auto-generated.

Initially, we'll just generate the node IDs...

Whenever we are at a node during traversal, we need to have a unique hash value for that particular traversal state. In other words, if we are at this node (not...

When pick events are handled within multiply-instanced Symbols, where the event originates within the subnodes of the Instances, the Symbol can get confused abo...

Sub-nodes of an Instance node are supposed to be temporarily inherited by the right-most leaf node of the target Symbol's subtree - algorithm described here: ht...

Nodes can be configured with callbacks, like this Rotate node that gets it's angle property off the data scope:

    SceneJS.rotate(function(data) {

Originally I thought it might be nice to control the scope of the listener the way ExtJS does, but there are other ways to do that, eg. using delegate functions...

Take "picked" listeners for example:

SceneJS.node({
            sid: "alpha",
 
            listeners: {
                "picked":{
                    fn: fun...

99% of the time a scene graph will be animated, and therefore rendered in a loop.

We need to encapsulate the render loop within SceneJS.Scene start and stop met...

At the moment a looping scene graph render goes at full-tilt, using a lot of CPU, even when not much is happening, ie. no animations.

Although SceneJS does its best to keep a pool of free WebGL resources available using LRU eviction, it should also be possible to explicitly free them.

At the moment the Picking Module computes pick shader colour for each object (node) thus:
