在模型中移动鼠标，在mousemove中执行raycaster导致CPU使用率高

Question

在模型中移动鼠标，在mousemove中执行raycaster导致CPU使用率很高，当我移动鼠标时，CPU使用率飙升至90% 这是我的代码：

this.container.addEventListener('mousemove', (e) => {
                console.log('intersect：', this.intersect(e, this.camera), this.objects)
                this.lastMove = Date.now()
            })
intersect(event, camera) {
            let raycaster = new THREE.Raycaster();
            let vector = new THREE.Vector2();
            vector.x = event.clientX / window.innerWidth * 2 - 1;
            vector.y = -event.clientY / window.innerHeight * 2 + 1;
            raycaster.setFromCamera(vector, camera);
            let intersectObj = raycaster.intersectObjects(this.objects, false);
            return intersectObj;
        }
