Although various three-dimensional technologies have been developed in recent years, few are able to display real time 3D images and video from any angle in the same way an object would appear to us in the real world. The new concept is a true three-dimensional display that allows users to view moving objects from any angle with the unaided eye, simply by walking around them as you would if you were looking at real 3D objects. I have invented a 3D Volumetric Display with clear picture and super clear depth; it has a 360 degree horizontal and 270 degree vertical viewing angle. New 3D volumetric display is entirely different from existing 3D TVs which produce translucent images even if input is solid image. This new 3D display can provide variable occlusion (0-100%) and variable opacity (0-100%) and partial or full cross-section view and cutaway view without losing parallax or perspective.
The major novelty of the 3D display I invented is that it gives more clear and realistic picture. In existing designs light from front and back of an object will pass through resulting in clogged image. In my 3D display this problem was remedied by using a new individual picture cells named sphexel (spherical picture cells). This sphexel has control over the direction of light to be emitted thus solving the above problem. The sphexels provide occlusion and opacity without losing perspective or parallax. Using this we can make images of 3D display from completely solid to translucent to transparent. The new 3D volumetric display can be used for R&D of complex systems especially for medical imaging.
Every frame, approximately 100 planar cross-sections of a 3-D volume are displayed on the LEDs in this volumetric 3-D display. For example, the 3-D scene is computationally decomposed into a series of "slices," which can be rectangular, disc-shaped, or helical cross-sectioned, whereupon they are displayed from a display surface undergoing motion. The image on the 2D surface (created by LEDs embedded in the surface) changes as the surface rotates. Due to the persistence of vision humans perceive a volume of light. The light-scattering characteristic of LED enclosures assures that it is visible from angles it is supposed to be.
Essence of the system is an planar surface where sphexels are arranged on it or helically arranged rods (like DNA molecules) and Sphexels arranged on each rods. The planar surface or rods are rotated at 1800 rpm and Sphexels are illuminated intermittently. Since rods are rotating we will not see the rods, we only see the part of the Spexels that is being illuminated for a fraction of a second. (Just like we can see rotating fan's leaves in fluorescent light but not in daylight) If input is programmed for an image or movie, we can view movie or picture on the rods.
