            semantic:'MODELVIEWPROJECTION'
        },
        u_diffuse: {
            semantic: 'DIFFUSE'
        }
    },
    diffuse: new Hilo3d.LazyTexture({

        src: '//img.alicdn.com/tfs/TB1va2xQVXXXXaFapXXXXXXXXXX-1024-710.jpg'
    })
}).then(material => {
    var geometry = new Hilo3d.PlaneGeometry();
    var plane = new Hilo3d.Mesh({
        material: material,
        geometry: geometry
    });
    stage.addChild(plane);
