meshで読み込むmaterialに6面の画像を設定しておく。
設定する順番は、右→左→上→下→正面→後ろ

				var materials = [
					new THREE.MeshLambertMaterial({map:texture_px,side:2}),
					new THREE.MeshLambertMaterial({map:texture_nx,side:2}),
					new THREE.MeshLambertMaterial({map:texture_py,side:2}),
					new THREE.MeshLambertMaterial({map:texture_ny,side:2}),
					new THREE.MeshLambertMaterial({map:texture_pz,side:2}),
					new THREE.MeshLambertMaterial({map:texture_nz,side:2})
				];
				material = new THREE.MeshFaceMaterial(materials);
				geometry = new THREE.CubeGeometry(100, 100, 100);
				
				mesh = new THREE.Mesh(geometry, material);
				
				scene.add(mesh);
