It can be used to perform SLERP (spherical-linear interpolation) between two rotations. Adding quaternions also cheaply adds the rotations, however quaternions need to be often normalized, or else they suffer from precision issues. mono Question Sorry about the click-bait, I know there are many many reasons why Quaternions and Bases are better than using Euler-Angles. You do not need to know the math behind quaternions, as Godot provides several helper methods that handle it for you.

Quaternion A quaternion is a mathematical representation used to describe 3D rotations in a way that avoids the "gimbal lock" problem associated with Euler angles. 0. basis I get some 3x3 matrix but I can't figure out which part, if any, is supposed to be the world rotation. spherical_cubic_interpolate, as well as the * operator. stable Question I am a new learner for GameDev in general, so I am trying to be thorough in my learning to avoid bad habits. So what you'll need to do is work out the Quaternion for the rotation, then multiply the vectors with that Quaternion. However quaternions need to be often renormalized, or else they suffer from precision issues. If I understand correctly, the quaternion should rotate the character around the axis (which was aligned with the basis). Surely there's some property or function to simply tell the object's global orientation, right?
