The VR controllers in the basic WebXR scene below are mere placehorders.
Their purpose is to show how the actual VR controllers - both in the Immersive Web Emulator's 3D viewport and in the WebXR scene the developer is building - would behave when using the "Point At" feature.
NOTE: WebXR frameworks/game engines like A-Frame, Three.js, Babylon.js, and PlayCanvas work differently. Therefore the primary goal of this prototype is to show the "Point At" feature, not to tell how to implement it.
