如何在ARKit中将3D对象（如带有两个侧杆的玻璃）设置到面部？

Question

我正在将平面用于2D玻璃（不带侧杆）。我如何添加3D对象？？

let node = SCNNode(geometry: faceGeometry)
glassesPlane.firstMaterial?.diffuse.contents = UIImage(named: imageArr[index])
glassesPlane.firstMaterial?.isDoubleSided = true

let glassNode = SCNNode()
glassNode.geometry = glassesPlane
node.addChildNode(glassNode)
