What is the volume display?
The volume display is a type of graphical display device that can create three -dimensional (3D) images. Images from volume displays are really 3D and have width, height and length. This makes images more realistic than simulated 3D graphics, such as those that are displayed on a standard flat screen. The three -dimensional graphics created by this type of display can be seen from any angle. More people can display a volume monitor image at the same time, and each viewer can observe the image from a different perspective. This gives viewers a very natural viewing experience.
Several different methods can be used to create volume graphics. One type uses a technique known as a "swept surface". The volume display of the sweeping surface uses a visual trick called the Persistency of Vision. The human eye looks like a fast -moving light as a picture such as the arc of the light that appears when the flashlight quickly waving through the air. Many volume devices use rapidly developing POVRCHY to create an illusion of solid shape.
The second method that is used to display volume 3D images is called static volume. There are no moving parts in this technique in the display area. Instead, mirrors and lenses are used to control bright light, such as laser. Very fast laser light pulses are focused on different points in the air. The persistence of vision convinces the eye that these light points are part of a single fixed object.
volume devices have many different applications. These types of displays are useful for medical training and diagnosis. For example, a 3D display can display a realistic image of a skull or heart and allow a group of medical students to study a structure on the eve of Angle. Volume displays are also useful for architects and builders who can visualize a construction project in three dimensions.
Research is underway in terms of intente methodsRakce with volume display. Sensors can enable users to manipulate and edit graphics without using the keyboard. For example, a camera connected to the display can watch hand movements and turn pictures as needed. These advanced methods of volume -interaction allow a very intuitive experience where users can literally address and touch three -dimensional images.
