How to convert a 3D vector to screen (or view) pixel coordinate system

How to get the central point of an entity or asset and convert it into the 2D screen or view coordinate system?
(ios / android)

There was a similar question some time ago, but they wanted to to the inverse - convert a screen point to a 3D point:

You want to project a 3D point to a screen coordinate. This is done by simply multiplying the 3D point with the viewProjection matrix. This will give you a point in normalized coordinates (-1 .. 1 on all axis). If the result is lower than -1 or bigger than 1 on any axis, then it's out of screen (actually out of the frustum). You then center and scale the result to convert to pixel coords.

Thanks! Will try and update this discussion once done.
