Way of rendering an image above a block in 3d space?

[SecondAmendment]

Is there a way of rendering an image above a block in 3d space? So like rendering a diamond pickaxe above a diamond ore signifying that a diamond pick can be used to mine that ore. or another example could be, rendering pictures of a chest's contents above the chest.

A similar topic was covered here recently (although I can't find it with all this spam) for a modded block involving a TESR, but I'm not sure about vanilla blocks.

Use the RenderWorldLastEvent to do that.

One can do this without the need of TESR's, by using a HUD (Heads Up display), and RayTracing.

 

Create an EventHandler for the RenderGameOverlayEvent or RenderWorldLastEvent.

The BlockPos can be gained from Minecraft::objectMouseOver.

The player is always Minecraft::thePlayer, client-side.

 

If the block/tile you are looking at is what you want, call a new method, from hereof called HUDBlock, passing the Minecraft instance.

HUDBlock should of course extend GUI.
In here, you can use GL however you want. Bind & render an image, draw strings on the screen etc.
