Questions tagged [quaternion]
Mathematical constructions, number systems. In 3D-graphics quaternions are used alongside vectors and matrices. One of the benefits of quaternions is that they overcome some rotational problems (known as gimbal locks) that are inherent to vectors and matrices.

How do you rotate an object that uses a quaternion to represent orientation in 3D from a 3 vector input with values from a gamepad?
I'm using unity3d to create a six-degree of freedom flying game. The game takes in input from a standard dual-stick gamepad (like the Logitech f310).
In unity each of the gamepad's joystick's axes are ...
