An ellipsoid is a three-dimensional shape that looks like a stretched or squished sphere. It is defined by its three axes, which can be of different lengths. The most common example of an ellipsoid is the shape of the Earth, which is slightly flattened at the poles and bulging at the equator. This shape helps scientists understand various geographical and physical phenomena. In mathematics, ellipsoids are important in fields like geometry and physics. They can be described using equations that represent their surface. Additionally, ellipsoids are used in computer graphics and modeling to create realistic representations of objects, making them essential in industries like gaming and animation.
