Paper Example on 3D Technology

Introduction

Three-dimension technique describes images by providing a perception of depth. In situations where a 3-D model is made interactive such that users feel involved with the occurrence in the scene, the experience is referred as a virtual reality. The technology of 3D can get drawn back to the times of photography. In the year 1844, an invention called stereoscope was made to for taking 3D photographic images. Improvements in technology became very common around the world, and in with times, the craze for stereoscopic cameras got employed. Early in the twenties, studio movies released films in 3D but using the latest versions of video cameras such as high definition (HD). A big push has been made towards 3D televisions in that there are channels displaying music performance, sports events, and educational shows in 3D.

How 3D Technology Works

For a vivid understanding of how the technology works and the involved techniques, it would be essential to describe the performance of human sight. Typically, humans have two eyes, 3 inches apart, and this distance provides slight different images which get transmitted to the brain. Consequently, the brain makes a space in where accurately the depth and range can get perceived. The 3D technology works in a way that to produce a similar area in the human brain, it requires tricking the brain into seeing various images from a familiar source. Well, minutely, multiple images are placed over each other alternating successively. With the use of devices like 3D glasses, for example, it helps dissect image and transmit to the right eye. Apparently, there is two dominant type of 3D glasses technology, active and passive. Active glassless changes the display electronically while passive dissect images in the absence of electronics. Mainly, the modern technology is trying to replicate how the human brain perceives the images. Automatically, the brain can figure out involved geometry concept like angles so that to synch the views.

Films are one of the 3D pioneers and thanks to its technological daring that 3D is achieved in motion pictures, polarized glasses, and anaglyph (Larkin, 2015). Usually, the term anaglyph refers to red and blue glasses wore to project a film in such colors. In that way, the eyes get individual perspective while the brain put the effect together. Also, other types of colors can be used as long as they are distinct enough to get isolated on the screen. The most common technique is the use of polarized glasses, which assumes that light can get polarized to take different positionings. For instance, while one image can be projected vertically, another can resume the horizontal direction. In that way, corresponding glasses allows a horizontal polarization in one eye, and a vertical in the other. The only challenge with the technique is that it requires a person to maintain one position of the head. Otherwise, tilting can distort waves propagation to the eyes, hence interfering with the 3D effect and colors.

In television, to project an image in 3D require the wearing of electronic glasses. Unlike in films which use unique silver coated screens that reflect light to viewing audience, Tv is not painted. Active and passive electronic glasses are synced to television for active opening and closing shutters in eyes, allowing each sight to observe one screen at a time. However, the shutters move quick in that they are hardly noticeable and are enabled by the refresh rate on the television sets. A 3d enabled Tv usually has high refresh rates.

Regarding how 3D images are created, the concept is based on geometry and precisions. To obtain a 3D image, it requires two versions of similar screen filed from a precise angle as if eyes are seeing the same scene. Typically, filmmakers require triangulating distance between cameras so that they tend to focus on one object (Larkin, 2015). Zooming, tracking and moving with a same is enhanced to sync up images. In modern films, cameras are bolted into a place to prevent unwanted jostling.

Controversial Issues in 3D Technology

One issue revolving a 3D technology, especially printing, is in treatments. There are ethical concerns about new treatments like the use of 3D printing in that it is not mainly clear whether the approach is safe and effective. The materials used in 3D printing bone replacement, like titanium, have already been used in orthopaedical surgeries and their safeties were tested over an extended period. Therefore, it not sure that those materials are still safe, as new risks might have developed. Also, concerning technology advancement, the printing might get combined with stem cell, derived cell lines, to make printed functioning organs in place of damaged patient's organ. However, it raises a question on how to tell in advance whether the approaches are safe.

Another controversy is whether a 3D printing can get used in human enhancement. A raised question is if technology can get utilized to develop organ or bone replacement, would it be right to use it formulate human capacities beyond the normal functioning? In other words, it not clear whether it is okay to consider replacing biological bones with artificial ones which are much stronger. In other instances, it is noticeable that 3D printing brings down issues of time and cost. Advancement in personalized medicine revolving 3D technology is in handy with increased disparities, between wealthy and well-abled individuals. Therefore, it remains controversy on whether specific treatment should stay available only to those who can afford additional costs.

Future Developments in 3D Technology

In future, material options and blended applications will increase in volume. From the bottom line, people are intensively relying on technology, and have become obsessed with additive manufacturing trends of 3D tech (Wimpenny, Pandey & Kumar, 2017). Printing industry informs that materials fit the gaps between production and prototyping thus increasing the number of technology applications. Developing materials is a high priority for many vendors, consequently bringing in more available high temperature, structural and flexible resources. In shutter glasses market, the available types are battery powered, and in future, it is anticipated that active shutter 3D glasses will be rechargeable design. Concerning active 3D technology, Tv syncs with glasses that uses infrared emitters, and are bulky and uncomfortable to wear. In future times, the development will reach the passive level where 3D glasses will not require to communicate via the emitter. Lighter and more comfortable glasses will get developed.

Other future developments include many industries and market adopting 3d printing solutions. For instance, in manufacturing processes, tooling and fixtures will be made in 3D while preceding the traditional machining. Additionally, business sectors will reap significant benefits in the design cycle, for instance where the nature of 3D becomes a core component of smartphones, laptops or tablets. There are speculations that food will someday be created using 3D technology, as offered by an experience of project nourished. New medical casts will get availed in large scale, created using 3D printing technology and it will help in fixing broken bones.
