World To Screen Point

Questions
#1

Whether there is a method to calculate the world coordinate XYZ to the screen point XY coordinate in Babylon. For example, U3D’s camera.WorldToScreenPoint (obj.transform.position);

may be this will help
var coordinates = BABYLON.Vector3.Project(vector3,
BABYLON.Matrix.Identity(),
scene.getTransformMatrix(),
camera.viewport.toGlobal(
engine.getRenderWidth(),
engine.getRenderHeight(),
));

So this is supposed WorldToScreenPoint

Yo @Atul_Sharma … What about ScreenToWorldPoint … How we we do that ?

I think i found the answer: If world to screen to point is Vector3.Project … then Screen To World point must be Vecter2.Unproject

From @Deltakosh

var vector= BABYLON.Vector3.Unproject(
                        mousePosition,
            	        engine.getRenderWidth(),
                        engine.getRenderHeight(),
                        BABYLON.Matrix.Identity(), scene.getViewMatrix(),
                        scene.getProjectionMatrix());

where mousePosition is the Vector2 with the screen X/Y coord you want to convert to world space

Right ???

Yes that is the right function but the first parameter is a vec3: you also need to provide a z value in screen space (value between 0 and 1).
