Picking updated mesh

[Dejan]

Hi guys,

I have a problem with mesh picking and it is a specific case.

When I create a ribbon like this, I can see it on the scene:

 var someRibbon = BABYLON.Mesh.CreateRibbon("ribb", [[new BABYLON.Vector3(0, 0, 0), new BABYLON.Vector3(10, 0, 0)], [new BABYLON.Vector3(0, 10, 0), new BABYLON.Vector3(10, 10, 0)]], false, false, 0, _scene, true, BABYLON.Mesh.FRONTSIDE);
            

On mouse down I am writing the name of the picked mesh in the log:

handleMouseDown: function(event){

var pickResult = _scene.pick(_scene.pointerX, _scene.pointerY);
var pickedPoint = pickResult.pickedPoint;
console.log(pickResult.pickedMesh.name); // writes ribb when I click on it
}

BUT, when I update the ribbon mesh after creation, like this:

  var someRibbon = BABYLON.Mesh.CreateRibbon("ribb", [[new BABYLON.Vector3(0, 0, 0), new BABYLON.Vector3(10, 0, 0)], [new BABYLON.Vector3(0, 10, 0), new BABYLON.Vector3(10, 10, 0)]], false, false, 0, _scene, true, BABYLON.Mesh.FRONTSIDE);
  someRibbon = BABYLON.Mesh.CreateRibbon(null, [[new BABYLON.Vector3(0, 0, 5), new BABYLON.Vector3(10, 0, 5)], [new BABYLON.Vector3(0, 10, 5), new BABYLON.Vector3(10, 10, 5)]], null, null, null, null, null, null, someRibbon);

Then I can see that the ribbon that is updated (moved 5units along z axis), but it can't be picked. Actually, the picker "thinks" that the ribbon is still in the old position.

Does someone have any idea how this could be solved?

Ping @jerome

this bug is fixed in the 2.5 : https://github.com/BabylonJS/Babylon.js/blob/master/dist/preview release/what's new.md

• Added BBox update on each ribbon based shape (ribbon, tube, extrusion, etc) on dynamic updates (jerome)

just refresh the ribbon._boundingInfo() else

Oh boy, it works now! Thank you for the quick response.
I really enjoy working with this engine. Keep up the good work
