It uses a special filter ( parallax barrier) so that each of our eyes sees different images (polarization) to create a 3D illusion. Nintendo has already showed us it’s possible with its 3DS gaming system. With wearable gadgets like Google Glass and Memoto, taking firsthand videos or snapshots of what you are doing. How to Capture Impressive 360-Degree Videos and Panoramas Non-intrusiveness aside, another reason why the idea of not having to wear special 3D movie glasses is so welcomed is because we want to see images in 3D with our naked eyes (or with our glasses or contacts) where we just don’t feel “artificial”. The same kind of enthusiasm in 4D films is also present since the 2000s, with the likes of major Hollywood films such as Avatar, Titanic, Iron Man 3 screened in 4D. It perhaps explains why the interest in 3D films was kindled again and again since the “golden era” in the 50s, when the first color 3D film from a major American studio, The House of Wax was released. The jump from 2D films to 3D and beyond satisfies the desires of the masses because it means we’re moving ahead in the realism department. With so much demand and emphasis on realism, it’s understandable why 3D and 4D films are gaining a foothold with the masses. Although 3D glasses aren’t the main cause of the undesirable physical sensations (they’re also partly due to the brain getting confused over the artificially created perspectives and angles onscreen), not having to wear those tinted glasses is still a big step forward in the pursuit of the ultimate immersive experience. The next logical step for the industry then may be to remove the need for 3D glasses altogether. Simplistically speaking, anaglyph films use color filtering, while the polarized 3D system limits the amount of light that enters each eye, whereas the active shutter system utilizes LCD screen technology to darken each of the two lenses of the 3D glasses in quick successions.Īll in all, the common goal across these systems is to make 3D imagery as natural and close to reality as possible.Īpart from enjoying high-quality 3D imagery, users also look forward to no uncomfortable physical symptoms like headaches, dizziness and nausea caused by prolonged usage of 3D glasses. However, these three types of 3D glasses aren’t interchangeable as each of them is designed for a specific 3D system. If you’ve tried those red and cyan anaglyph 3D glasses before, you’d probably agree that the polarized or shutter glasses offer much better visual quality. Synchronicity is especially crucial, as the flow of the movie is very delicate and can easily be disrupted when the special effects don’t match. With an audience that’s so physiologically and mentally engaged with a movie, it becomes even easier to detect any out-of-sync physical sensations that accompany the 3D or 4D film. We essentially lose ourselves in the movie. The coordination of scenes that rouse our " fight or flight" response, for instance a car chase scene, combined with vibrating or moving seats, makes the brain register the effect and even cause us to feel as if we are in the scene we are watching. What we see stimulates our sight, what we feel trigger our physiological reflexes intensely. For the latter, physical effects occur at the exact points of the movie where such effects are expected.įor instance, the viewing of a cartoon character sneeze at the audience gets the 4D effect when water sprays or air spurts are utilized with precision timing. This is where synchronicity comes into the picture not just for 3D, but also 4D films. It goes without saying that the illusion of depth won’t work unless the two perspectives play at the same time. Read more Synchronicity & Physiological Arousal Turn Your iPhone Into A 3D Camera With PoppyģD is seeing a revival in terms of innovations – from absolutely breathtaking 3D street art to 3D. This is how the perception of depth comes into play in reality whenever we visually process our physical 3D environments. The 3D illusion is created when our brain receives different images from each of our eyes and automatically merges them into a single image. This overlapping explains why the screen looks blurry if you’re not wearing 3D glasses).ģD glasses are to be worn, so that the images are correctly filtered to your left or right eye. This can be done by using two cameras to capture the filming at different angles at the same time, or with the cheaper (but more tedious) alternative of creating layered images with computer technology.Įach of the two perspectives is meant to be seen by either your left or right eye – each of your eyes will see different perspectives simultaneously. Put simply, a stereoscopic 3D film works by emphasizing the illusion of depth perception, which is achieved by artificially creating two perspectives for the film. Unleash your inner film buff with these 10 websites dedicated to movie trivia.
