How to Render a Waypoint

[Paperclippy]

Hello, essentially what I am trying to create is a waypoint. A point in the world is selected and text is rendered to the screen, always facing the player, with the same scale, but seemingly at this point in the world. I've been thinking about something in minecraft similar to this, or maybe a mod that does essentially this that is open source, but I can't think of anything. All of the mods that I have looked at that have something like this are not open source. Any ideas?

Well you know the position of the waypoint and the current position of the player. You also know the current rotation and yaw of the player as well. You can also figure out when to check for if the area is loaded. Take that as you will.
