I control the camera by adding “ArcRotateCamera()”.
I want to create points on specific areas, when I click there will be a path to the point click like this demonstration Interface interactive

I want to interact with my interface by moving the camera to the clicked area.

you will find attached my poor code

 <!DOCTYPE html>
 <html>

<head>
	<!--<meta charset="UTF-8">-->
       <style>
    html, body {
        overflow: hidden;
        width: 100%;
        height: 100%;
        margin: 0;
        padding: 0;
        font-family: OpenSans, tahoma, arial, sans-serif;
        color:white;
    }

    canvas {
        width: 100%;
        height: 100%;
        touch-action: none;
    }
</style>
<script src="/babylonTest/babylon.js"></script>
</head>

<body>
<canvas id="renderCanvas" touch-action="none"></canvas> <!--//touch-action="none" for best 
results from PEP-->
<script src="/babylonTest/coffrageScene.js"></script>
</body>

and the coffrageScene.js

   var canvas = document.getElementById("renderCanvas"); // Get the canvas element 
   var engine = new BABYLON.Engine(canvas, true); // Generate the BABYLON 3D engine

    BABYLON.SceneLoader.Load("", "coffrage.babylon", engine, function (scene) {

        //as this .babylon example hasn't camera in it, we have to create one
        var camera = new BABYLON.ArcRotateCamera("Camera", 0, 0, 7, new BABYLON.Vector3(0, 
       0, 0), scene);
        //camera.setPosition(new BABYLON.Vector3(0, 10, 0));

        camera.attachControl(canvas, false);
       
        scene.clearColor = new BABYLON.Color3(2, 1, 1);
        //scene.ambientColor = new BABYLON.Color3.Red;


        engine.runRenderLoop(function() {
             if (camera.beta < 0.1)
          camera.beta = 0.1;
        else if (camera.beta > (Math.PI / 2) * 0.92)
          camera.beta = (Math.PI / 2) * 0.92;

            scene.render();
        });

        window.addEventListener("resize", function () {
            engine.resize();
        });
    });

Best Regards
