In differential geometry and geometric optics, a caustic is the [[Envelope (mathematics)|envelope of rays either reflected or refracted by a manifold.
It is related to the concept of caustics in optics.
Description
The ray's source may be a point (called the radiant) or parallel rays from a point at infinity, in which case a direction vector of the rays must be specified.
