Glm quaternion to euler

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). This is equivalent to yawing 180° opposite to the way you were facing, then pitching over backwards to reverse your heading, then rolling over to correct for the inversion. ie. paypal hiring process

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.
