A-Frame - Raycast Three.JS 3D Object

我有两个对象，一个圆柱体和一个多边形，表示a帧场景中的Three.js 3D对象。我只想让多边形在悬停时发生变化，就像圆柱体一样。

我在这里有一个工作演示：演示

当光标悬停在圆柱体上时，文本HOVERED将显示在屏幕上，圆柱体的颜色将使用Raycaster组件进行更改。如何对多边形执行同样的操作？

多边形是这样创建的：

AFRAME.registerComponent('foo', {
init: function() {
let points = [];
points.push(new THREE.Vector2(0, 0));
points.push(new THREE.Vector2(1.5, 0));
points.push(new THREE.Vector2(2.5, 1));
points.push(new THREE.Vector2(2.5, 2.5));
points.push(new THREE.Vector2(1, 3.5));
for (let i = 0; i < points.length; i++) {
points[i].multiplyScalar(0.25);
}
let shape = new THREE.Shape(points);

let extrudedGeometry = new THREE.ExtrudeGeometry(shape, {
amount: 1,
bevelEnabled: false
});
// Geometry doesn't do much on its own, we need to create a Mesh from it
let extrudedMesh = new THREE.Mesh(extrudedGeometry, new THREE.MeshPhongMaterial({
color: 0xff0000
}));
this.el.object3D.add(extrudedMesh);
let geometry = new THREE.ShapeGeometry(shape);
let material = new THREE.MeshBasicMaterial({
color: 0x00ff00
});
let mesh = new THREE.Mesh(geometry, material);
this.el.object3D.add(mesh);
}
});

谢谢。
