I was making a 3d game and wanted to calculate the degree of rotation of the character. I have the quaternion points in (x, y, z, w) format and wanted to convert it to [0-360] angle. I looked at examples of how to do it here on SO and other website too but all I could find was wrong conversion methods and outdated ones. What is the right way to convert quaternion to angle degrees. This website does the conversion but doesn't show the MATH how: quaternion to angle degrees convertor. Any help is appreciated. Thanks in advance
