# Quaternion to euler Unity

When you read the .eulerAngles property, Unity converts the Quaternion's internal representation of the rotation to Euler angles. Because, there is more than one way to represent any given rotation using Euler angles, the values you read back out may be quite different from the values you assigned. This can cause confusion if you are trying to gradually increment the values to produce animation. See bottom scripting example for more information When converting from quaternion to euler, the X rotation value that this implementation returns will always be in range [-90, 90] degrees. Though the difference is that of the Y and Z axis ranges. Unity has a range of [-180, 180] degrees, whereas this implementation uses [0, 360] degrees. It still functions identically due to the properties of trigonometric functions. If you do want the range in of all axes being in range [-180, 180] you can do Spatial rotations in three dimensions can be parametrized using both Euler angles and unit quaternions. This article explains how to convert between the two representations. Actually this simple use of quaternions was first presented by Euler some seventy years earlier than Hamilton to solve the problem of magic squares. For this reason the dynamics community commonly refers to quaternions in this application as Euler parameters Instead, the X, Y & Z values are converted to the Quaternion's internal format. When you read the .eulerAngles property, Unity converts the Quaternion's internal representation of the rotation to Euler angles. Because, there is more than one way to represent any given rotation using Euler angles, the values you read back out may be quite different from the values you assigned. This can cause confusion if you are trying to gradually increment the values to produce animation This is very very close to Unity's Quaternion.Euler and quaternion.eulerAngles. The discrepancies are small enough that they shouldn't matter for any application. public static Vector3 QuaternionToEuler (Quaternion q) { Vector3 euler; // if the input quaternion is normalized, this is exactly one

### Is there a conversion method from quaternion to euler

• Unity internally uses Quaternions to represent all rotations. They are based on complex numbers and are not easy to understand intuitively. You almost never access or modify individual Quaternion components (x,y,z,w); most often you would just take existing rotations (e.g. from the Transform ) and use them to construct new rotations (e.g. to smoothly interpolate between two rotations)
• Creating and manipulating quaternions directly Unity's Quaternion class has a number of functions which allow you to create and manipulate rotations without needing to use Euler angles at all, and these are the ones you should use in most typical cases. Each of these links to the Script Reference with code samples
• mathematics of rotations using two formalisms: (1) Euler angles are the angles of rotation of a three-dimensional coordinate frame. A rotation of Euler angles is represented as a matrix of trigonometric functions of the angles. (2) Quaternions are an algebraic structure that extends the familiar concept of complex numbers. While quaternions are much les
• Quaternions differ from Euler angles in that they use imaginary numbers to define a 3D rotation. While this may sound complicated (and arguably it is), Unity has great builtin functions that allow you to switch between Euler angles and quaterions, as well as functions to modify quaternions, without knowing a single thing about the math behind them

By specifying Euler interpolation you are telling Unity that you want the full range of motion specified by the angles. With Quaternion rotation however, you are saying you simply want the rotation to end at a particular.

### Unity - Scripting API: Transform

1. Unit quaternions, known as versors, provide a convenient mathematical notation for representing spatial orientations and rotations of elements in three dimensional space. Specifically, they encode information about an axis-angle rotation about an arbitrary axis. Rotation and orientation quaternions have applications in computer graphics, computer vision, robotics, navigation, molecular.
2. If you end up needing quaternion's to Euler angles, but you need an arbitrary rotation order, I came across a site with conversion code. Sometimes the trick is just finding the right rotation order. (Btw, the orders that have the same letter twice, like XYX, are proper Euler angles, but the ones like XYZ are Tait-Bryan angles)

Representing Attitude: Euler Angles, Unit Quaternions, and Rotation Vectors James Diebel Stanford University Stanford, California 94301{9010 Email: diebel@stanford.edu 20 October 2006 Abstract We present the three main mathematical constructs used to represent the attitude of a rigid body in three-dimensional space.

Quaternion to Euler Angle Conversion Fundamental Concept The underlying concept of the present method of converting a given quaternion, Q G, to the corresponding Euler angles of the given rotation sequence, i1 i2 i3 , is to perform the quaternion rotation operations on selected unit vectors and derive the required Euler angles from the results.
