Assembly: Microsoft.Xna.Framework (in microsoft.xna.framework.dll)

Syntax

Copy

[TypeConverterAttribute("typeof(Microsoft.Xna.Framework.Design.QuaternionConverter)")]
[SerializableAttribute]
public struct Quaternion : IEquatable<Quaternion>

Remarks

Quaternions represent a rotation. Typically, they are used for smooth interpolation between two angles, and for avoiding the gimbal lock problem that can occur with euler angles.
