Here are flight simulations and displays created using three.js. There are currently three versions:

• WebGPU versions with NodeMaterials (WebGPU) - the most advanced, mostly updated to r168.
• WebGL2 versions with NodeMaterials (WebGLN) - updated to r165.
• WebGL2 versions (WebGL2) - updated to r158, but will be updated to r168.

Note: NodeMaterials can no longers be used with WebGL2 - so these versions will eventually be deleted.

In these examples, you can fly and land an animated model aircraft (airplane or helicopter). In external view, you can look around the aircraft using the mouse and shift key. In the FM2, you can select an internal view with animated instruments and pilot.

Fly from an island base (with smoking volcano) over an animated ocean and a moving carrier:

* WebGL2	-	[rev 231014]

See here for flight instructions. Fly to an airbase over procedurally-generated farmland near mountains:

* WebGPU	-	[rev 240913] r168
* WebGL2	-	[rev 231014]

The horizon remains level since, unlike an airplane, a helicopter is primarily designed to fly upright. See here for more information about this simulation.

In these examples, you can select the camera viewpoint, including level, locked and cockpit (FM2 only). You can pan around the aircraft using the mouse and you can pitch and bank and turn the aircraft using the buttons at the lower left. The FM2 has animated parts that you can activate with various buttons on the upper right.

Here is a depiction of the Earth from space. Creating the image of earth is a common exercise for three.js programmers and many examples are available online. This version is more complex and depicts the earth using the correct angles for the sun, moon, stars and some planets. The moon is displayed in the correct position for a specific year. The texture for the stars was obtained from NASA. Here is a discussion of interesting facts I learned while creating this example.

This is an example of great circle navigation used in long distance flights. This shows the ferry route taken by B-29s during WWII.

This is a diorama showing the inner planets of the solar system. Not only are the orbits of the planets on different planes, they are not perfect circles. Consequently, I used data look-up tables to compute the position of the planets at different places in their orbits. This program shows how to rotate rotating objects around a common center - a useful feature of three.js.
