Adding nodes programatically

[Tim]

I'm working on a 3d data visualization prototype.  I create a scene with the x/y/z axis as planes then programatically add data points, e.g.:

SceneJS.createScene({

type: "scene",

id: "theScene",

canvasId: "theCanvas",

nodes: [....

Then I instantiate the scene like many of the examples:

var scene = SceneJS.scene("theScene");

Finally I add data points programatically with this code:

var n = scene.findNode("disclosure-events");

var deptArr = getDisclosureEvents();

for ( var i = 0; i < deptArr.length; i++ )

{

n._targetNode.addNode(generateNode('p'+(i+1), deptArr[i]));

}

var generateNode = function(id, dept)

{

var pt = new Object();

pt.type = 'geometry';

pt.primitive = 'triangles';

pt.id = id;

pt.positions = dept.getPositions();

pt.normals = dept.getNormals();

pt.uv = null;

pt.uv2 = null;

pt.indicies = dept.getIndices();

pt.colors = dept.getColors();

return pt;

}

Finally I start the scene.  The axis show up and function like I would expect.  However the data points do not.  I suspect the scene is compiled when first instantiated and subsequent modifications ignored.

Any help would be appreciated.

(Btw, I first tried to use the geo-load service but couldn't figure out a way to add multiple nodes.)
