What is Quaternion?

In 3D computer graphics, a quaternion is a mathematical representation of rotation. Unlike Euler angles, which are prone to gimbal lock issues, quaternions provide a more stable solution for representing orientation. Quaternions use four parameters (scalar and vector components) to describe rotations in three-dimensional space.

Meaning of Quaternion

The significance of quaternions lies in their ability to address challenges associated with representing rotations in 3D space. Gimbal lock, a phenomenon where certain orientations result in a loss of one degree of freedom, is avoided with quaternions. They provide a more robust and computationally efficient way to interpolate between rotations, making them a preferred choice for animating 3D objects.

Application of Quaternion

Quaternions are extensively used in 3D computer graphics, animation, and game development. They play a crucial role in character animation, camera movement, and object manipulation. By providing a stable representation of rotations, quaternions contribute to smoother and more realistic motion in virtual environments. They are also employed in robotics, physics simulations, and spatial orientation applications.
