I'm working with three.js and attempting to create procedural texture which can be stored and then applied to objects later in a session.
Ideally, I would like to create these textures only once each.
I would like to be able to sample from existing assets to create new textures.
Within the three.js example, a version of this is shown where the texture is re-rendered every frame. http://threejs.org/examples/webgl_rtt.html
I have created an example of what I hope to achieve here: http://www.forsako.com/ThreeJS/RenderTest.html
Unfortunately, to make this work, I had to re-render the texture each frame.
Is there a way to perform this rendering so that the texture persists over multiple frames until I tell it to be released? Source from my main program follows.

I've created pointcloud with all points in an exact plane. I want the pointcloud to be highlighted and shown as a rectangle shape when the mouse is rolled over. For that, I think the pointcloud has to be converted in to a mesh, first.
I've googled for hours and tried to read thee.js documentation too. But couldn't find any solution. Could you please help me convert this pointcloud to a mesh. Thank you very much

Here is a quick and dirty modification of your sample, basically it creates a thin box with the same dimensions than your pointcloud and toggle its visibility when the mouse is getting over (using a raycaster). As far as I know there is no direct/built-in way to turn a pointcloud into a plane/mesh.

I am using three.js to create a scene that has a model on it. I have a plane on which the model sits, and a spotlight shining on the model.
The model is made up of a number of different objects. All of the objects are set to receive and cast shadows. Shadows are being cast on the model itself from other areas of the model.
The plane, however, won't receive shadows. I'm unsure why.
I have adjusted the spotLight.shadowCameraNear and spotLight.shadowCameraFar properties to ensure both the model and plane are within the shadow area. Still nothing.
Below is a screenshot of the model with the spotlight visible.
I have the shadowmap enabled and set to the soft maps:
renderer.shadowMap.enabled = true; // Shadow map enabled
renderer.shadowMap.type = THREE.PCFSoftShadowMap;

I am getting an error that says : TypeError: array[i].call is not a function
and is pointing to line 7484 of three.js library.
I have included the three.js library using:
<script src="https://cdnjs.cloudflare.com/ajax/libs/three.js/r73/three.js"></script>
So as you can see, its the v73 and I haven't touched the code. What could be the problem?
The error only comes after screen is clicked and then mouse pointer is dragged, so it must have got to do with that piece of code.
Assuming that you want the scene to render when OrbitControls sends a change event, you'll have to change the code to:
controls.addEventListener( 'change', render );
.
.
.
function render() {
renderer.render( scene, camera );
}
renderer.render( scene, camera );
I'm using some sample code and I just added my model using the JSONLoader. I can load objects with just one texture and they paint just right. But after I import an object, in this case a house with different textures/materials (grass, roof, windows, etc), but my model just appears in plain gray.
This is my example up and running:

What's the right way to load mats/textures to an object like mine?
Thanks so much.
You are importing only the geometry from the JSON model file, why not importing both geometry and materials?
loader = new THREE.JSONLoader();
loader.load( "models/residential_001.js", function( geometry, materials ) {
house = new THREE.Mesh( geometry, new THREE.MeshFaceMaterial( materials ) );
house.position.set( -120, 100, 1 );
house.scale.set( 1, 1, 1 );
scene.add( house );
} );
I use three.js TrackballControls for rotating object.
Here is simple application - http://zheden.elitno.net/
I cannot rotate object horizontally when mouse position is on left side of scene. Vertical rotation is ok.
Could you please tell me what is wrong?
Here is my code:
var scene = new THREE.Scene();
var camera = new THREE.PerspectiveCamera(75, 1, 0.1, 1000);
var controls;
var renderer = new THREE.WebGLRenderer();
renderer.setSize(500, 500);
document.body.appendChild(renderer.domElement);
var geometry = new THREE.CubeGeometry(1,1,1);
var material = new THREE.MeshLambertMaterial(
{
overdraw: true,
color: 0x00aa80,
shading: THREE.FlatShading
});
var cube = new THREE.Mesh(geometry, material);
scene.add(cube);
var directionalLight = new THREE.DirectionalLight( 0xffffff );
directionalLight.position.x = 1;
directionalLight.position.y = 1;
directionalLight.position.z = 1;
directionalLight.position.normalize();
scene.add( directionalLight );
var light = new THREE.DirectionalLight( 0xffffff );
light.position.set( -1, -1, -1 );
scene.add( light );
var light1 = new THREE.AmbientLight( 0x222222 );
scene.add( light1 );
camera.position.z = 3;
controls = new THREE.TrackballControls( camera );
controls.rotateSpeed = 1.0;
controls.zoomSpeed = 1.2;
controls.panSpeed = 0.8;
controls.noZoom = false;
controls.noPan = false;
controls.staticMoving = true;
controls.dynamicDampingFactor = 0.3;
controls.keys = [ 65, 83, 68 ];
controls.addEventListener( 'change', render );
