var loader = new THREE.TextureLoader();
loader.load ( texturefile, function ( thetexture )
// this defines a function to be called whenever the file is loaded
{
thetexture.minFilter = THREE.LinearFilter;
theobject.material = new THREE.MeshBasicMaterial ( { map: thetexture } );
});
You will now get something like the following:
