Getting distance between you and path. about arkit-scnpath HOT 3 CLOSED

To check if focusNode is on the path, all you really need to do is check if a hitTest at the centre of the screen hits the geometry of the SCNPath.

For the minimum distance to any point on the path, or any one of the control points, you can use this package I'd previously made for routing graphs. Build up the graph with SCNPathNode.path and then check Graph3D.findPointOnEdge(), or to find the closest control point use Graph3D. findNearestNode(). Passing the camera transform position as the parameter to each function.

FYI finding the closest point on the graph will only consider the centre of the path.

I wouldn't include something like that in this repository as SCNPath has the sole purpose of creating the geometry, not for being an end-to-end graphing and AR wayfinding package.

Thank you very much for your answer!
