👉 In computational geometry and computer graphics, a "pre-bound" is a set of points that are contained in some plane or surface but not necessarily on it. This can be used to represent objects that lie outside the plane or surface they're currently defined on. For example, if we have a 3D object represented by a set of vertices and edges, and we want to capture the shape of this object in a computer graphics pipeline, we might define an "outer bound" for the object's
