Wikipedia
In projective geometry an ovoid is a sphere like pointset (surface) in a projective space of dimension . Simple examples in a real projective space are hyperspheres ( quadrics). The essential geometric properties of an ovoid $\mathcal O$ are:
- Any line intersects $\mathcal O$ in at most 2 points,
- The tangents at a point cover a hyperplane (and nothing more), and
- $\mathcal O$ contains no lines.
Property 2) excludes degenerated cases (cones,...). Property 3) excludes ruled surfaces (hyperboloids of one sheet, ...).
An ovoid is the spatial analog of an oval in a projective plane.
