Virtual cameras and 3-D gaming environments in a gaming machine

A disclosed gaming machine provides method and apparatus for presenting a plurality of game outcome presentations derived from one or more virtual 3-D gaming environments stored on the gaming machine. While a game of chance is being played on the gaming machine, two-dimensional images derived from a three-dimensional object in the 3-D gaming environment may be rendered to a display screen on the gaming machine in real-time as part of the game outcome presentation. To add excitement to the game, a 3-D position of the 3-D object and other features of the 3-D gaming environment may be controlled by a game player. Nearly an unlimited variety of virtual objects, such as slot reels, gaming machines and casinos, may be modeled in the 3-D gaming environment.

Gaming machine having transparent LCD in front of variable display device, the LCD having a light-guiding plate and a reflective plate

During a slot machine game, game effects are also displayed on a liquid crystal panel 39d provided in a reel display window unit 39, and thus the liquid crystal panel 39d serves as a new machine component for performing game effects. Therefore, new effects for the game can be performed on the liquid crystal panel 39d, which facilitates maintaining the novelty of game effects. Further, the openings 5b, 6b and 7b are formed corresponding to the rows of the variable displays of the symbols. Accordingly, by means of the light guiding plates 39g also located between the opening 5b and the opening 6b, and between the opening 6b and the opening 7b, the light from the cold-cathode tubes 40a is guided toward the liquid crystal panel 39d.

One method of the invention includes first verifying the identity of a potential player of a gaming event, such as by verifying the age of the player. If verified, the fingerprint of the player is obtained and the fingerprint is stored in association with an assigned identification code. When a player requests to participate in a gaming event from a remote location, the player's identification code is received from the player and is used to locate the corresponding stored fingerprint. The player then transmits their scanned fingerprint. If the transmitted fingerprint and stored fingerprint match, the player is verified as entitled to participate in the gaming event.
