For the second part of Machine Problem 2, you will write a simple flight simulator using WebGL to handle the display. Your "plane" will fly over the terrain you generated in the last MP.  Add a cloud of fog to your terrain.

Flight and Fog

The airplane should automatically move forward at a fixed speed. The user will control the pitch and roll of the airplane through the arrow keys.  This video explains airplane motion.

• Pressing the left (right) arrow key will make the plane roll to its left (right).
• Pressing the up (down) arrow key will cause the airplane to pitch up (down).
• Pressing the + (-) key will increase (decrease) the airplane's speed

You will need to implement the following:

1. A quaternion based viewing system.
   Note: The glMatrix library provides support for using quaternions...and you should use it [link].
2. A user interface that minimally implements the arrow-key and +/- key controls described above. You can add additional controls to affect yaw if you wish.
3. Your webpage should include text instructions describing how the user interface works. 
4. A cloud of fog, placed over and around your terrain. This tutorial should help with implementing fog (you'll have to modify some code from the tutorial).
   Note: The fog computation should be done per-vertex, which means implemented in the vertex shader. 
5. Implement controls which turn the fog on and off in the scene.

Grading

Name your submission as ${NetID}_MP2B.zip and submit it to Compass. Include all of the files necessary for your application to run locally (this includes gl-matrix-min.js and webgl-utils.js).  

The assignment will be graded based on the following scale:​

• 1 pts - Documented and interactive UI: Using keyboard or mouse to control your plane interactively and your user interface explained on your webpage
• 1 pts - Translation: The plane should move forward automatically.
• 1 pts - Roll: Apply correct rotation when your plane rolls left or right..
• 1 pts - Pitch : Apply correct rotation when your plane pitch up and down.
• 1 pts - Speed: Include the ability to speed up and slow down the plane.
• 1 pts - Fog: Include a layer of fog over and around the terrain (and a way to turn the fog off and on).
