This tool was made as a request to mimic a tool in Unity that creates a miniature version of the scene that the developer to make changes to their levels.
What you are seeing here is a faked 3D miniature scene of the current level. This is done with a single plane that rotates to face the developer. From there I did some math to project the location and angle of the VR pointer on the 2D plane to match up with were the developer would be clicking in the actual scene.
The end result is that you can select actors in the scene via the faked miniature. This 3D minimap can be taken with you around the level so that you can edit pieces of your scene without having to actually move around in VR. You can bring the area you want to modify to you.
