This article explains how to convert between the two representations. Actually this simple use of "quaternions" was first presented by Euler some seventy years earlier than Hamilton to solve the problem of magic squares. For this reason the dynamics community commonly refers to quaternions in this application as "Euler parameters".Oct 29, 2018 · The function quaternion_to_euler is designed to give you that sequence of Euler angles. The real weakness of the conversion function occurs when the pitch angle is ± π 2. Then cos β = 0 and the formulas for roll and yaw do not work.

Note that a quaternion describes just the rotation of a coordinate frame (i.e. some object in 3D space) about an arbitrary axis, but it doesn’t ... Oct 29, 2018 · The function quaternion_to_euler is designed to give you that sequence of Euler angles. The real weakness of the conversion function occurs when the pitch angle is ± π 2. Then cos β = 0 and the formulas for roll and yaw do not work. You can convert Euler angles to a quaternion and back to non-equivalent Euler angles.

If you need to use Euler, try to keep pitch in -90 to +90, and roll in -180 to +180; if (pitch > 90) { pitch -= 90; yaw += 180; roll += 180; } if (roll > 180) { roll = 360 - roll; } or something like that.
