ADULT film-makers have jumped on the Avatar bandwagon by revealing 3D porn movies.

Hot on the heels of James Cameron's hi-tech blockbuster, Bad Girls in 3D has launched films that can be watched on an exclusive 3D setup.

The Bad Girl's system — described as a "turnkey digital 3D viewing system" — was revealed at the AVN Adult Entertainment Expo in Las Vegas yesterday.

Film producer Lance Johnson said: "For several decades, the adult entertainment industry has driven adoption of every significant new entertainment delivery system - the VHS home-video craze in the 1980s, the satellite television mania in the 1990s and the present day Internet.

"2010 and beyond will be all about 3D."

Visitors to the Las Vegas show flocked to the hi-tech stall to don the 3D "active shutter glasses" to try out the virtual films.

The firm's 3D package consists of a 60-inch (152-centimeter) 3D TV, a compact computer server, and shutter glasses that sync with the screen to trick eyes into viewing in 3D.

The Bad Girls system is priced at £2,000 and a subscription to the online video library costs £10 a month.
