@Deltakosh can I zoom to where I click not to the target of camera ?
thank u dud :relaxed:

Not directly. You first need to set the target where your click then zoom

@Deltakosh and how can I get the clicked area ?

well that can be done with scene.pick (by retrieving pickResult.pickedPoint)

@Deltakosh I used :

scene.onPointerDown = function (evt, pickResult) {                  
   if (pickResult.hit) {
            clickedPosition.x = pickResult.pickedPoint.x;
            clickedPosition.y = pickResult.pickedPoint.y;
            clickedPosition.z = pickResult.pickedPoint.z;

but I want to avoid one click because I use one click and still pressed to rotate the camera, is there a function that use Double clicked, I searched in scene doc I didn’t find

you can use scene.onPointerObservable and check the evt type

See line #33:

Nice idea!!
