   ambientLight(); // 添加环境光
   threeObj.render(); // render函数必须调用 才会渲染
   threeObj.initLight(); // 添加灯光
   threeObj.initAxesHelper(1000) // 添加辅助线
   loadGlb("/model/pump.glb",undefined,[10,5,5]); // 添加glb模型
}

checkIntersection

// 初始化的代码已省略
document.addEventListener("pointerdown", (event) => {
    checkIntersection(event, (model) => {
        console.log(model) //获取鼠标点击的模型
        return true;
