Is there no support for rotation by Euler angles?

Boost.QVM does not seem to support rotation by Euler angles.

I think that following overload should be added.

• rot_mat by Euler angles
• set_rot for matrix type by Euler angles
• rotate for matrix type by Euler angles
• rot_quat by Euler angles
• set_rot for quaternion type by Euler angles
• rotate for quaternion type by Euler angles

Function template euler_angles should be added that convert quaternion to 3-dimensional vector type. It probably use zero_magnitude_error.

If you like, I will fork, implement it and send a pull request.

I've implemented this for matrices, both for Tait–Bryan angles and Euler angles.

Thank you.

Is this method implemented. I would love a euler_angles method or is it named something else?

See:

• https://boostorg.github.io/qvm/#rot_mat
• https://boostorg.github.io/qvm/#mat_set_rot
• https://boostorg.github.io/qvm/#mat_rotate

Thank you for the response, but was hoping to either extract the euler angles from a matrix or a quaternion. These methods seems to only apply euler angles to the matrices.

Right, that's what this issue was about. There is a conversion of matrix to a quaternion, if that helps: https://boostorg.github.io/qvm/#quat_convert_to.
