Abstract: Embodiments of the present disclosure relate to simulation, generally, and in some embodiments, more specifically to simulating a flight path of a golf ball. In such embodiments, a computer may be adapted to determine a first trajectory of the golf ball based on one linear expression; determine variations based on a flight path of the golf ball according to a first plane and a second plane, the first plane and second plane having orthogonality; adjust the first trajectory based on the variations; and provide a virtual golf ball with a virtual flight path based on the adjusted trajectory.

Abstract: Collapsible golf simulators include an enclosure mounted over a base. The base has a play surface configured to support a person using the golf simulator, and the enclosure is configured to receive golf balls hit from the play surface. A container is configured to be removably mounted to the base, and at least one component of at least one of a computer system and a graphical display system is disposed within the container. In additional embodiments, collapsible golf simulators include a collapsible enclosure mounted over a base. The enclosure is configured to receive a physical golf ball hit from a play surface on the base. The collapsible enclosure includes a plurality of arcuate rib members each having ends pivotally mounted to the base. The rib members are configured to pivot relative to the base and carry a sheet of pliable material. Methods of using such apparatuses are also disclosed.
