示例
请考虑以下示例，了解上述代码的工作原理 −
解释
我们使用 new BABYLON.Vector3(x,y,z) 进行定位的方式，也可以应用相同的旋转方式。在这里，您可以使用 new BABYLON.Vector3(x,y,z) 进行旋转，也可以使用 box.rotation.x,box.rotation.y,box.rotation.z。
要旋转，您必须以弧度为单位给出角度。一度等于 0.01745329252 弧度:1° = π/180° = 0.01745329252 弧度。例如，boxb.rotation = new BABYLON.Vector3(Math.PI/2,0.5,0);
