We all are accustomed with things like photocopier or 2D scanner. They took the picture of real objects and then turn it into 2D photos. The working style is more or less same in 3D scanner or 3D laser scanner, but the output is not 2D, the output you can see in 3D form. You can see its application especially in computer gaming field. The environments and various objects have been usually created in the 3D scanner and transformed into 3D objects, and then the experts incorporate them in to the game. That is why when you play 3D games you can feel as if you are actually inside the game and feeling the heat of the game.

Today 3D laser scanner is not only used in computer games, but also you can see their usage in special effect movies and computer generated movies. The most applications of 3D scanning are reverse engineering and prototyping, photogrammetry and industrial designs. You can find different scanning machines in different technologies. The looks, characteristics and price also vary with that. When you need to transform a real time object into digitized format you need to be very cautious so that the measurements can be perfect. The word photogrammetry has come from two commonly used words, photograph and science of measurements ?metric?. Earlier when there was only 2D modeling, the experts were unable to calculate the depths and other measurement correctly. That is why 3D surface modeling has come up so that one can understand the positions perfectly by seeing the pictures. They are just the miniature of the real object but in a bit more detailed form. You can observe even small details and measurements there.

The name reverse engineering can create a bit of confusion in many people's mind. When you analyze something to understand how it works and how the experts made it to work, is called reverse engineering. There are many old aged machines which need to be rebuilt. These reverse engineering can help us a lot to understand how these machine were built 3-4 decades ago, and they were supposed to work. After getting the detail reports, the experts can then start rebuilding these machines all over again. To accomplish these tasks successfully, you need to use laser scanning technology. It will capture the frame and then demonstrate all the functionalities in 3D virtual world. That is why many companies are using these techniques to make things easier for them. Though, you need to be cautious because it may happen that the result produced in 3D laser scanning is not 100% correct, that is why you need to test the whole thing and then start working in them.

3D animations have also become hugely famous. You can use these technologies to make 3D animations. But for that you first need to think about targeted audiences and then start working on that. 3D virtual world is interesting and can make you see many things which you were not able to see physically. Many companies are utilizing these features, especially those who work on GIS or digitized maps. 3D scanner, photogrammetry and reverse engineering have changed the definition of maps and digitized photographs. If the progress continues at this rate, soon we will touch some new sky of success.
