Drone World 3D Map
Drone World is a ThreeJS demo where you can view an entire 3D terrain using your mouse and arrow keys.
The experiment is set in a lush, green mountainous area surrounded by a body of water. After you’re done exploring the place, you can tweak the settings a bit.
There are a variety of options for changing the level of details, including drone position. You can also tweak the appearance of the sun, sky, and ocean to a certain extent.
