1.3.8 Euler Angles
Euler angles are often used to describe rotations. They represent an orientation in three
parameters, angles commonly referred to as yaw, pitch and roll. Euler angles apply rota-
tions sequentially over the axes of a coordinate system, each axes will be rotated by its
respective angle such that the roll will be applied in
z
, the pitch will be applied in
x
and
finally the yaw will be applied in
y
.
