These nodes are for working with quaternions.

A **quaternion** is a way of representing a rotation in 3D space using 4 coordinates (x, y, z, w). Unlike rotations expressed in Euler angles (yaw, pitch, and roll; or angles about the x, y, and z axis), quaternions avoid the problem of gimbal lock.

- Combine Quaternion Rotations (vuo.quaternion.combine): Finds the rotation that would result after rotating by each of the terms.
- Make Quaternion from Angle (vuo.quaternion.make.angle): Calculates a quaternion that represents a rotation in 3D space.
- Make Quaternion from Vectors (vuo.quaternion.make.vectors): Calculates a quaternion that represents a rotation in 3D space.
