Allow access to methods to control the camera in VR (the camera or scene methods)

[dianafonte]

I need to focus on a node and reset the view to the starting point programmatically. At this moment this is not possible in VR because the library does not expose the camera, scene, renderer or controls methods.

I would like for these methods to be accessible, so I can change the camera's position.

@dianafonte thanks for reaching out.

These items are not exposed because in VR/A-Frame mode the environment is not quite the same as for WebGL/ThreeJS.

This component offers a simple use case of the force-graph A-Frame component. For more sophisticated cases, you can always use the aframe-forcegraph-component and setup the A-Frame scene/camera/controls scaffolding yourself. I'd suggest this approach if your case is custom.

An alternative option, albeit slightly hacky, is to manipulate the A-Frame monitored DOM elements. For instance, to modify the camera position using this method, you can do something like:

document.querySelector('a-entity[camera]')
  .setAttribute('position', '0 0 300')
