In projective geometry, an ovoid is a specific type of geometric structure that can be thought of as a type of surface. More formally, an ovoid is defined as a closed, convex set in a projective space such that every line intersects the ovoid in at most two points. This makes ovoids analogous to ellipsoids in Euclidean geometry.
