FreeCamera

自由视角相机

const camera = new BABYLON.FreeCamera(); // 自由相机

ArcRotateCamera

该相机总是朝向一个指定的目标位置，且可以进行旋转，旋转中心为目标位置

const arcRotateCamera = new BABYLON.ArcRotateCamera(
  name: string,
  alpha: number,  // 绕着竖轴旋转
  beta: number,  // 绕着水平轴旋转
  radius: number, // 里目标的距离
  target: Vector3,  // 目标
  scene?: Scene,
  setActiveOnSceneIfNoneActive?: boolean
);

camera.parent = mesh; //跟随mesh变换
camera.lockedTarget = mesh; // 锁定mesh，此时无法变换alpha,beta，可以修改radius

FollowCamera

跟随目标移动

const camera = new BABYLON.FollowCamera(
  name: string,
  position: Vector3,
  scene?: Scene,
  lockedTarget?: Nullable<AbstractMesh>
);
