Quaternion Structure
Defines a four-dimensional vector (x,y,z,w), which is used to efficiently rotate an object about the (x, y, z) vector by the angle theta, where w = cos(theta/2).

Syntax
[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.
