An oblate spheroid is a three-dimensional shape that is like a sphere but slightly flattened at the poles and slightly bulging at the equator. It is often used to describe the shape of certain celestial bodies, such as planets like Earth. The term "oblate" refers to the flattening at the poles.
The word "sphere" originates from the Latin word "sphaera," which came from the Greek word "sphaira" meaning "globe" or "ball." The term has been used to describe a round, three-dimensional geometric shape with all points on its surface equidistant from the center.

The term for the creation of the illusion of three-dimensional texture on a two dimensional surface is "visual texture." There are many ways of achieving visual texture, including relief, shading, and perspective.
