enableDamping: true,

dampingFactor: 0.05,

autoRotate: false,

enableRotate: true,

enableZoom: false,

enablePan: false,

isLockRotate: true, //是否锁定旋转。

enablePolar: false,

polarSpeed: 0,

enableDolly: false, // 禁止缩放

// 关键配置：锁定垂直方向（上下）的旋转角度范围为0，彻底禁止上下操作

minPolarAngle: Math.PI / 2, // 最小俯仰角 = π/2 (90度)

maxPolarAngle: Math.PI / 2, // 最大俯仰角 = π/2 (90度)

// 水平方向（左右）旋转无限制，可360°旋转

minAzimuthAngle: -Infinity,

maxAzimuthAngle: Infinity,

},

这个配置有问题吗?怎么无法实现禁止模型的上下转动呢?
