Euler vs Quaternion - What's the difference?

Video Description

3D software describes orientation and interprets rotation using math, and the most common way to do this is with Euler and Quaternion Values. Euler is the common X, Y, and Z, 3 dimensional, ordered, series of values that suffers from gimbal lock. Quaternion represents the W, X, Y, and Z 4 dimensional, spherically interpolating (SLERP), series of values that do not suffer from gimbal lock; Though, may be harder to visualize.
