Three.js纹理映射方向不正确

Question

我正在尝试将简单的纹理贴图应用到立方体，但是当应用纹理时，它会旋转90°CCW。

仅仅为了我的测试，我正在为所有面孔使用相同的uv映射：

window.head = function(){
    var txSplitX = 1/64;
    var txSplitY = 1/32;
    var mesh;
    var cube = new THREE.CubeGeometry( 100, 100, 100);
    var material = new THREE.MeshBasicMaterial( { map: THREE.ImageUtils.loadTexture('assets/charSkin/Superman.png') } );
    var faceTx= [
            new THREE.Vector2(0.125,0.75),
            new THREE.Vector2(0.25,0.75),
            new THREE.Vector2(0.25,0.5),
            new THREE.Vector2(0.125,0.5)   
        ];

    var j=0, k=1;
    for(var i=0; i<6;i++){
        cube.faceVertexUvs[0][j] = [faceTx[0],faceTx[1],faceTx[3]];
    cube.faceVertexUvs[0][k] = [faceTx[1],faceTx[2],faceTx[3]];
        j+=2;
        k+=2;
    }

this.mesh = new THREE.Mesh(cube,  material);  
}

如何在每张脸上获得正确的纹理方向？
