I hope this helps . I may be mistaken, but I thought that the 2D canvas API was designed in such a way that browsers can make use of hardware acceleration, but they have chosen not to yet. I expect the implementations of canvas 2D to improve dramatically as WebGL progresses.

wish help you to fix your issue I am brand new to three.js and am having some difficultly creating a simple 2d circle sprite in Webgl. , Here is the pattern to follow:
code :
function generateTexture() {

    var canvas = document.createElement( 'canvas' );
    canvas.width = width;
    canvas.height = height;

    var context = canvas.getContext( '2d' );

    < insert drawing code here >

    return canvas;



var texture = new THREE.Texture( generateTexture() );
texture.needsUpdate = true; // important!

var material = new THREE.SpriteMaterial( { map: texture } );

sprite = new THREE.Sprite( material );

fixed the issue. Will look into that further Looks as if the WebGL code was all correct. However, I was never invoking the function bindAllTextures to actually set up the texture with webgl for rendering.

Hope that helps Here is an update fiddle. http://jsfiddle.net/6sygocvb/1/
Note that all elements added to a SpriteContainer must have the same SpriteSheet.
code :
var stage = new createjs.SpriteStage("canvas");
var container = new createjs.SpriteContainer(ss);

around this issue If I'm not mistaken your sphere has a radius of 5 while your sprite is positioned way beyond the sphere at 128,128,128. You need to either increase your sphere radius or reduce your sprite position to something that lies within the radius.
code :
var geometry = new THREE.SphereGeometry(256, k, k);

This might help you Probably the most common way is to use a unit quad with unit quad texture coordinates and pass in a texture matrix to multiply the texture coordinates to select the part of the texture you want.
code :
 // vertex shader
 attribute vec2 texcoord;
 uniform mat4 texMatrix;
 varying vec2 v_texcoord;

 void main() {
    v_texcoord = (texMatrix * vec4(texcoord, 0, 1)).xy;
 // vertex shader
 attribute vec2 texcoord;
 uniform vec2 uvOffset;
 uniform vec2 uvScale;
 varying vec2 v_texcoord;

 void main() {
    v_texcoord = texcoord * uvScale + uvOffset;
