Define Quaternion Math

Quaternions form an interesting algebra where each object contains 4 scalar variables sometimes known as euler parameters not to be confused with euler angles these objects can be added and multiplied as a single unit in a similar way to the usual algebra of numbers. In mathematics the quaternions are a number system that extends the complex numbers. X y z w.

Unit quaternions also known as versors provide a convenient mathematical notation for representing spaceorientations and rotations of objects in three dimensions.

Define quaternion math. Quaternions are a skew field of hypercomplex numbers. The helperdrawrotation class is used to illustrate several portions of this example. They were first described by irish mathematician william rowan hamilton in 1843 1 2 and applied to mechanics in three dimensional space. They have found applications in aerospace computer graphics and virtual reality.

Both vectors are assumed to be unit length. Both vectors are assumed to be unit length. Quaternion is defined by four floating point numbers. Vierheit sind ein zahlenbereich der den zahlenbereich der reellen zahlen erweitert ähnlich den komplexen zahlen und über diese hinaus.

Quaternions extends a rotation in three dimensions to a rotation in four dimensions. Quaternion defines a single example of a more general class of hypercomplex numbers. This avoids gimbal lock and allows for smooth continuous rotation. Compared to euler angles they are simpler to compose and avoid the problem of gimbal lock compared to rotation matrices they are more compact more numerically stable and more efficient.

Die quaternion von lateinisch quaternio ionis f. Sets a quaternion to represent the shortest rotation from one vector to another. In matlab quaternion mathematics can be represented by manipulating the quaternion class.
