Quaternions are often used in computer graphics because of both issues with Euler angles (like gimbal lock) AND the computational complexity difference. Quaternions are just more efficient to compute.

Quaternions are one of at least two ways to model rotations in a 3D space. Most people are familiar with the classic Euler angles which cover yaw, pitch, and roll.

Irish physicist, astronomer, and mathematician Sir William Rowan Hamilton introduced quaternions, a non-commutative extension of complex numbers, on October 16, 1843.. Benjamin Olinde Rodrigues had ...

Our senior research engineer Hamish Todd will be speaking on Tuesday 21st March on “Math in Game Development Summit: A Visual Guide to Quaternions and Dual Quaternions.” In case you didn’t know, a ...

October is the anniversary of the discovery of quaternion algebra, a discovery made by an Irish man, who graffitied his idea on a bridge along the Royal Canal in the 19th century. William Rowan ...
