Quaternion algebra extends complex numbers into four dimensions, offering a powerful tool for representing rotations and orientations in three-dimensional space. It is fundamental in fields such as computer graphics, robotics, and aerospace engineering due to its efficiency in avoiding gimbal lock and its compact representation of spatial rotations.

Complex numbers extend the real numbers by including the imaginary unit 'i', which is defined as the square root of -1, allowing for the representation of numbers in the form a + bi, where a and b are real numbers. This extension enables solutions to polynomial equations that have no real solutions and facilitates advanced mathematical and engineering applications, particularly in fields like signal processing and quantum mechanics.

Three-dimensional space is a geometric setting in which three values, often referred to as dimensions, are required to determine the position of an element. It is the physical universe we live in, where objects have length, width, and height, allowing for the representation and manipulation of objects in a realistic manner.

Gimbal lock occurs when using Euler angles to represent 3D rotations, causing a loss of one degree of freedom as two of the rotational axes align. This can lead to unexpected behavior in systems relying on these rotations, such as in animations or aircraft control, necessitating alternative representations like quaternions to avoid the issue.
