Nehru Science Centre, Worli, Mumbai, has opened its new film 'BUGS' in 3D Science Show  for its visitors from 7^th August 2008. This state-of-the-art facility is one of its kinds in this part of the country. The visitors to the 3D Science Show will experience an out of the world immersive experience in which the near realistic visuals will appear to come out from the static screen right in front of their eyes.
The shows would be conducted every hour at the Centre for the general public & school groups. Each visitor can avail this facility at an extra entry ticket of Rs.20/-. Organised School groups will, however, be offered 50% discount.

How it works?
Humans perceive 3 dimensional (3D) view of the surrounding using two eyes. Both our eyes see a slightly offset view of the scene. Our brain combines the two slightly different views in a complex way that creates a unique perception of depth. That’s why we need two eyes. The working of 3D show is really very simple. It works the same way as our eyes. A distance of about 2.5 inches separates our eyes, and because of this distance we see objects from two different points of view. While 2.5 inches seems quite small, it's good enough to accurately gauge distances as far away as 25 feet. The images from these two different viewpoints are sent to the brain and this difference, which is termed as parallax, is interpreted as depth.The 3D Science shows system reveals a two-eye view of the world from the screen. In this 3D system, depth-of-field is simulated using Polaroid glasses, which allow light to pass selectively based on a phenomena of physics known as Polarization.
History of 3-D: The first experiments with 3D movies started in the 1920s and 1930s, but the 3D technology was patented in around 1900 in Great Britain, US and France. It started with red and green (or blue) glasses. This combined dual projection was shot from slightly different angles into one three-dimensional perspective. Like most film technology, it was put on hold during the Second World War. Initially the 3D technology was considered just a novelty but soon changed with the onset of television that began to keep ticket-buyers at home and out of movie theaters. 3D movies were marketed as unique and innovative and not present in the TV.  Along with such advances as Cinemascope and Stereophonic Sound, 3D movies became a popular attraction in the early 1950s. The successful 1952 release of Bwana Devil, a low-budget action feature, created a massive flood of 3D, or stereoscopic cinema, as it was technically named, released to the public over the next few years. In India too films like Shiva and Chhota Chetan were created in the 3D films category.
The technology used in the 3D projection system at NSC, Mumbai projects slightly different viewpoints of same images, which are projected through left and right polarizers. This polarized light from the screen enters your eyes through polarized glasses. The special spects enable the left eye to see only the left eye image and right eye to see only the right eye image. The polarized glasses allow only one of the images enter into each eye because each glass has a different polarization angle. The lenses used in Polarized 3D Glasses are specially cut at opposing angles. These are used for viewing stereo pairs projected through left and right polarizing filters, thus making it possible to see 3D impression of the movies projected. 
The film BUGS  is based on two different creatures having altogether very different lifestyles. It describes Mantis and Butterfly, from their birth to their inevitable encounter in the rainforests, where predator meets its prey. ‘Bugs’ stars Papilio, a butterfly, and Hierodula, a praying mantis. The two go through growth phases and attain maturity following a cycle. Finally fluttering amid the blooms, Papilio dips her proboscis deep into the base of the flowers to drink sugary nectar, pollinating the plants as she forages, a process essential to her survival. Unbeknownst to her, Hierodula is lurking nearby, awaiting his daily meal. It is survival of the fittest, as Hierodula snaps her up in his extended jaws, releasing her wings, which flutter down to the surface of the river. Papilio’s brief life may be over but it has not been wasted. Nearby, her daughter has just hatched, and the cycle of life goes on.
