The surface of a sphere is defined in that manner.
Because that is how a polyhedron is defined.
In geometry, a circle is a two-dimensional object, so it does not have a surface. Only three-dimensional objects have surfaces. A disc is a flat, circular three-dimensional object.
Perspective, perhaps.

Visual texture.
Trompe L'oeil, maybe, though it's not really related to the Math, Algebra, Geometry category.
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.

It is called perspective.
Linear perspective is the term defined as the use of horizontal and diagonal lines to create the illusion of depth in a two-dimensional artwork. By converging lines to a vanishing point on the horizon, artists can achieve a sense of space and distance on a flat surface.
