javascript - Correct UV mapping Three.js

Question

I'm trying to map the UV-texture correctly, but failing...

I've got the next result in my app:

The result isn't that I was awaiting. I want to have the next described view:

You need to look at PlaneGeometry.js and understand how the UVs are set. Then you will be able to figure out how to reset them. This should work -- there are two triangles per "face".

for(var i = 0; i < geometry.faces.length / 2; i++) {

    geometry.faceVertexUvs[ 0 ].push(
    [
        new THREE.Vector2( 0, 0 ),
        new THREE.Vector2( 0, 1 ),
        new THREE.Vector2( 1, 0 ),    
    ] );

    geometry.faces[ 2 * i ].materialIndex = i;

    geometry.faceVertexUvs[ 0 ].push(
    [
        new THREE.Vector2( 0, 1 ),
        new THREE.Vector2( 1, 1 ),
        new THREE.Vector2( 1, 0 ),    
    ] );

    geometry.faces[ 2 * i + 1 ].materialIndex = i;

    materials.push( createTexture( i ) );

}    

//geometry.computeFaceNormals(); // not needed
//geometry.dynamic = true; // not needed
//geometry.uvsNeedUpdate = true; // not needed since plane has not been rendered yet
