What is a 3D projection?

three -dimensional or 3D projection, which is often called 3D projection mapping, is the transmission of three -dimensional data on a two -dimensional plane. Scientists, engineers and designers often use this type of mapping system to make computers or pen and paper models of three -dimensional objects. Objects can be attracted to a scale or with a perspective, but both properties cannot be maintained intact after translating three -dimensional coordinates to two dimensions. Although 3D projections usually refer to the modeling itself, it may also refer to the projection of images that seem to be in three dimensions, such as those that are seen in 3D movies.

The act of transferring three -dimensional information to a two -dimensional plane means that something must be lost. There are two main ways to use 3D projection, and each has its own positive and negative properties. One way to project a three -dimensional image on a two -dimensional surface is a perspective. Sterspective makes the image look into the eye as ifIt was three -dimensional, although the sizes of parts of this object, if measured, would not be proportionally correct. Another way to use two dimensions to represent three is the use of a system called orthographic projection. In this system, measurements are accurate, but the object will not seem to have depth.

For 3D projections there are a number of uses. The design and design of engineering use three -dimensional coordinate systems in designing buildings and structures. Computer graphics also use a 3D projection when modeling a three -dimensional object or environment in the two -dimensional space of the computer screen. Science and mathematics can also use this type of projection in modeling or graph of various natural phenomena and equations.

3D projection can also refer to the projection of two -dimensional images onto the screen in such a way that it seems that the viewer exists in three dimensions. The technology for creating a two -ups seems to beThe specific image has depth is available from the 1920s, and although many improvements have been improved, the basic principles are the same. Instead of one picture, two images are placed on the screen that slightly overlap, simultaneously. When a person is wearing special glasses, either colored filters or polarized filters, each eye is able to see only one of these images and the brain translates the information that each eye receives into one three -dimensional image.
