3D Technology Information

While it is generally agreed that high definition television, the television technology is the future, there is a more advanced type of technology on the horizon that could eclipse! This technology is 3D HDTV.

It has a resolution of the image resolution of an HDTV set is comparable, but it is also capable of producing images that appear three dimensional. In fact, these devices can give the viewer the impression, surrounded by images. For example, a land surveyor, who attended a demonstration with a prototype of this kind of butterflies HD TV and petals fly off the screen by describing it as a very realistic!

Of course, technology 3D video is not really something new. In fact, 3D movies were popular for decades, but had the disadvantage that viewers wear special glasses to provide polarized glasses to create the illusion of a three-dimensional image. The 3D technology is based on the HDTV is different. A high resolution 3D monitor actually shows different images in different angles. In this way, each slightly different images in the eye of the viewer and give the illusion of depth. The different angles by more pictures of the TV screen, the more realistic three-dimensional effects.

Photo realistic 3D rendering is not just for fun and relaxation. It is a big business. Many industries use photo-realistic renderings. These include areas such as cinema and film, interior design, graphic design and product design.

What is ray tracing? This technique for producing an image by pursuing the path of light through a pixel in the image plane. The technique can produce images of greater realism than scan line rendering methods

In the past, Ray tracing is a very high quality and advanced. However, it is no longer the case. Rendering and virtualization technologies have addressed the state of hyper-realism. In the hyper-realism, rendering, and physical reality are very difficult to distinguish. Since many systems and rendering algorithms are physically correct in terms of simulation and calculation.

The latest technology for photo-realistic rendering, had the ray tracing core is exceeded global illumination. What is global illumination? It is a collective term for various technologies (including raytracing and radiosity) that are used to produce realistic renderings directly from the calculations and indirect lighting. Global illumination includes algorithms that take into account not only the light directly from light sources but also when light rays from these sources are indirectly reflected by other surfaces in the 3D environment.

Technology for the realistic representation of global illumination is the use of HDRI environment maps. HDRI stands for High Dynamic Range Imaging. This technology allows a greater dynamic range of exposure techniques to make digital standard, producing true to life imaging.

Industrial design has been revolutionized by 3D printing technology. All of a computer mouse on a mountain bike has been awarded 3-D shape. This technology has been extended to contour lines and the dynamics of new production.

Rapid Prototyping Technology

Before the advent of 3D printing, prototyping had laboriously by a master are manufactured in a large workshop that specialized tools. A model perfectly proportioned wood generally requires several days to finish even with the employment or work highly qualified and competent. There were significant delays between the design phase of a project, the prototype stage.

Completed drawings was time to bring a viable model, as the images are carefully followed to avoid errors. Rapid prototyping of a need for the physical model developed in a period shorter time produce a much lower cost. You can now this technology for 3D models on your printer with great attention to detail and precision printing. Successive layers are printed that he had to construct an image that can be used for the traditional wax or molding high-epoxy high tech.

Self-Replicating Printer

Self-replicating, rapid prototyping, or RepRap, which is currently allows you to unique and innovative ideas that are operational in a short period of time to create. Three dimensional objects can also be printed at home with a price cut expected from RepRap 3D printer classic. Rapid prototyping is a new level as a manufacturer of medical devices, industrial or jewelry designers and automotive engineers can be taken to create complex products and artifacts, without requiring costly infrastructure industry. The common assumption is that technology is another version of the original, you can quickly create parts and make parts defective resources low. It is ideal envisioned a future where you can design and build your own machine in the comfort of your home could.

The 3D printing technology comes into the fight in 1986, but has won only in 1990. In recent years, 3D printers are available in the market at low costs, but the performance levels are set high standards.

The technology is under rapid prototyping systems and includes a fully functional ink jet printing as well. The technology of 3D printing is preferable because it promotes full color prototypes.

The 3D object is created layer-wise, one after the other places a fine on another. A fine powder, consisting of plaster, corn starch and resins are used to build the layers. These layers are bonded by an adhesive to the inkjet printhead. The shape of each cross section of the desired object is determined by a CAD file. The force of these impressions may be increased, thermo-set polymer impregnation or wax.

Some printers use a liquid photopolymer for the formation of the layers mentioned. The photopolymer layer is a cure with a UV lamp (UV), is connected to the inkjet printer.

There is also a method called Fused Deposition Modeling (FDM), in which a nozzle deposits of molten polymer into a mold layer by layer. The strength of these objects can be increased by inserting a metal one.

The crossing of the finish cutting of thin layers allows an exact form of laminate. Each technology has its own advantages and disadvantages. However, consider the most important factors are the speed of the surface, the cost of the printer object and the materials used (powder or polymer) and the capabilities of color among others.

Some applications of 3D printers include architectural design, print organs, primary metal smelting, education and others.

Technological progress is a phenomenon sweeping in all areas of modern life. Brotherhood pressure is no exception, and 3D printing has revolutionized the printing industry with soaring pace of technological progress. 3D printing is the magic word in the mainstream of today’s technical fields. 3D printing is a special form of production, which is closely associated with traditional printing rapid prototyping. The creation of a three-dimensional object images in the printing process is carried out by the overlay and on consecutive cross-sectional view of the material. One merit of this common perception is that 3D printers are relatively cheap to buy and print faster than shared printers, technology-based production of food additives.

Although the prototype continued pressure from its dominance in the market also has 3D printing with outstanding merits and potential end users are customers. This technology is becoming increasingly popular jewelry, shoes and various designs. Areas of architectural and automotive and medical fraternities have also in the bottom of the 3D printing technology developed today.

This printing process is fast print output, in contrast to the typical prototype of the pressure which takes time and hard work preserved. This impression is satisfied with the speed and reduces the work with the output quality achieved. This is the cheapest way to produce prototypes with rapid prototyping, which the mark is made by 3D printing.

This impression outperforms the other methods and traditional printing methods, such as stereo lithography. The reason is that 3D printing for rapid and cost-designed. It is clearly defined guidelines, the space for critical reflection and the phases of construction, particularly in areas where the dimensional accuracy in design are less important. The presentation of this idea is as convenient for conceptual design engineering, where the strength of the prototype is not required. 3D printing resolution is made in the thickness of the layers and in the resolution in dpi XY. Standard thickness is usually / – 100 microns (0.1 mm). The XY resolution can be connected to the laser printer.

First a little history. The first began in 3D millions of years with humans. Yes, we see things in 3D. All human beings have binocular vision. This means that we have two eyes separated by a distance of 2-3 cm from each other. This allows us to see deep and see the world in 3D. This separation will be seen every look at the world from a slightly different angle. The brain combines these two images in a. It includes the spatial differences and uses them to calculate the distance. That’s how we measure the depth and distance.

A simple way to understand this principle is to keep your thumb at arm’s length and cover one eye with your hand. Then try your hand on the other eye. How do you switch between your eyes open your thumb, you should go “back and forth, view on the merits.

Stereoscopy was invented in 1838. There is much debate on the first 3D film, but “The arrival of the train” filmed in 1903 by the Lumiere brothers. They were the inventors of cinema, and is often described as the highlight film first time. When it was published, the public panicked because they thought the train was about to plunge right into it! The funny thing is it was probably one of the first remake. The film is remake of the original which was released in 1895! And you wonder why Hollywood keeps remake films. He was practically born for this!
