glm::mat4 transform1 = glm::eulerAngleYXZ (euler.y, euler.x, euler.z); Your variable 'euler' must be the same sequence type as the function you specify to transform it into a rotation matrix. After looking here it looks like the function 'glm::eulerAngles' returns 'XYZ' as pitch, yaw, and roll.Given a vector r, you can convert r to a pure quaternion v (w=0) using: v = i r_x + j r_y + k r_z p = q* v q gives you the rotation of pure quaternion v with quaternion q. This should be straightforward to adapt to glm, and it should be more efficient and simpler than converting to a matrix rotation first.

When you cross 90 though, say to 91°, glm wants to keep y less than 90, so it picks an equivalent Euler angle triplet, (180, -89, 180).

Converting quaternions to matrices is slightly faster than for Euler angles. Quaternions only require 4 numbers (3 if they are normalized. The Real part can be computed at run-time) to represent a rotation where a matrix requires at least 9 values. However for all of the advantages in favor of using quaternions, there are also a few disadvantages.However it still doesn't give me full solution to my problem. It works when converting from euler to quaternion and from the same quaternion back to euler, but when I create a quaternion from axis angle using this equation: qx = ax * sin (angle/2) qy = ay * sin (angle/2) qz = az * sin (angle/2) qw = cos (angle/2) and convert it to euler angles ...glm::mat4 transform1 = glm::euler AngleYXZ (euler.y, euler.x, euler.z) ; Your variable 'euler' must be the same sequence type as the function you specify to transform it into a rotation matrix.
