Watching cinema in 3D predates the runaway success of 2009's Avatar, but James Cameron's blockbuster has turned the screws on a burgeoning technology, making it again synonymous with summer tent-pole films.
The movement is creating massive revenues for studios and theaters throughout the world, with moviegoers readily plunking down premium coin for the experience of seeing the stars reach out and touch them.
Last week, Pacific University hosted a 3D technology forum. The conference, which drew experts from the realms of technology, film and medicine, focused on the future of 3D entertainment in the home and the theater and how that technology may impact the study of optometry.
The event drew 75 registrants to Pacific's Forest Grove campus to see presentations from 3D experts like Phil Lelyveld, who manages the Consumer 3D Experience Lab at the University of Southern California, and 3D filmmaker Chris Haws.
The technology to make 3D films dates back to the invention of motion picture cameras, but technical requirements for accurate 3D imaging made stereoscopic film twice as difficult to produce as 2D films.
Three-dimensional film hit its initial stride in the 1950s, when thrill-seeking filmgoers donned the iconic red-and-blue glasses to glimpse everything from Alfred Hitchcock's 'Dial M for Murder' to a rash of B-grade horror films such as the classic 'House of Wax,' starring Vincent Price.
But beyond the technical requirements of getting the image right, the technology imposes challenges for filmmakers as well.
'If your actors aren't looking at each other,' Lelyveld said, 'you can see it in 3D.'
3D made brief comebacks in the 1970s and 1980s, typically for derided horror fare like 'Amityville 3D,' 'Jaws 3' and the third 'Friday the 13th,' which all used their status as the third films of their respective series to cash in on inflated ticket prices.
Until recently, however, 3D was relegated to IMAX films and theme park rides tied in with such movies as 'Terminator 2: Judgment Day' and 'Honey, I Shrunk the Kids.'
In 2003, however, director Robert Rodriguez re-adopted the medium for his third 'Spy Kids' film, that year's only 3D offering. For each of the following years, the number of 3D films grew exponentially as filmmakers, particularly animators, used advances in technology to enhance their films.
In 2009, the movement came to a head with the release of 11 mainstream films, including blockbusters 'A Christmas Carol' and 'Coraline,' as well as the Oscar-winning animated film 'Up.'
But it was James Cameron's blockbuster 'Avatar' that seemed to seal the deal. The decade-in-the-making film used a specially designed 3D Fusion Camera System to add rich layers to films and went on to become one of the highest grossing films of all time.
Now, 3D appears to be here to stay, with 22 films released by major studios using the technology in 2010, including 'Toy Story 3,' 'How to Train Your Dragon' and 'Alice in Wonderland.'
So far this year, no fewer than 13 films have already debuted in 3D, including the most recent 'Pirates of the Caribbean' offering and the comic book adaptation 'Thor' - and the summer is just getting started. From the latest Harry Potter film to an update of 'Conan the Barbarian,' an additional 10 mainstream films will hit theaters vying for the 3D audience, with an additional 14 slated to hit theaters by year's end.
Below is a rundown of 3D flicks hitting cinemas like Cornelius Nine and Bridgeport Village this summer.

All in all, it'll be a multi-dimensional summer at the movies, so try to look good in those glasses.
