You can utilize a 2D canvas as a texture for the object you wish to "paint" on
var canvas = document.createElement('canvas');
var texture = new THREE.Texture(canvas);
var material = new THREE.MeshBasicMaterial( {map: texture, side:THREE.DoubleSide } );
var mesh = new THREE.Mesh(
new THREE.PlaneGeometry(canvas.width, canvas.height),
material
);
Remember to update the texture when changing the canvas content.
