The present invention is a system that allows a number of 3D volumetric display or output configurations, such as dome, cubical and cylindrical volumetric displays, to interact with a number of different input configurations, such as a three-dimensional position sensing system having a volume sensing field, a planar position sensing system having a digitizing tablet, and a non-planar position sensing system having a sensing grid formed on a dome. The user interacts via the input configurations, such as by moving a digitizing stylus on the sensing grid formed on the dome enclosure surface. This interaction affects the content of the volumetric display by mapping positions and corresponding vectors of the stylus to a moving cursor within the 3D display space of the volumetric display that is offset from a tip of the stylus along the vector.

The invention provides a multiple projector rotating screen based 3D display system, including: one rotating screen, driven by motor; an image processing device, decomposes the 3D physical model in the cylindrical coordinate system in a series of multiple angular 2D images and sent to the data processing unit of all projectors; at least two projectors arranged around the rotating screen, synchronously project a 2D image with the corresponding angle on one of the rotating screen, thereby restructured the 3D image similar with that of actual objects. The invention may improve the updating rate, resolution and gray step-scale, based on the current available technical level of software and hardware, the lower cost, high display effect of 3D display device may be manufactured.

A light surface display for providing a three-dimensional image including a plurality of particles suspended within a volumetric display. A first projection system projects sequential slices of electromagnetic energy of one or more wavelengths along the length and width of the volumetric display energizing particles to form a two-dimensional image. A second projection system projects translational slices of electromagnetic energy of one or more wavelengths that intersect with the energized particles across the depth of the volumetric display. A control system synchronizes the projection of the image source and the activation source such that the two-dimensional image and the translational slices energize the particles for a pre-determined length of time so that the particles illuminate to form an illuminated three-dimensional image.

Volumetric three-dimensional (3-D) graphical or computer displays are disclosed herein that are capable of presenting objects, data, scenes or other visual information in a realistic or solid-like manner, allowing for an unaided observer to observe such static or moving objects from multiple perspectives with natural depth-cues and superior image quality. We utilize in this refined approach moving-screens formed from particulate-arrays and we preferably optically project multiple image sub-slices on each such flying-screen as it passes through the image-volume thereby minimizing particulate mass-flow since only once screen per image-volume is needed to present the several or many necessary slices of each volumetric frame.

Methods and systems of and for using volumetric display technology including volumetric display technology to create three-dimensional objects for various industries, including, but not limited to solar, automotive and / or other technological areas that use 3D printing or additive manufacturing.

A volumetric display apparatus is disclosed which includes, one or more movable generator means to receive a multitude of light sources, wherein said light sources have a non-linear spatial distribution and are independently accessed for unequal access durations, in which said light sources have multiple-element structure with independent direction and intensity control, in which light blocking means controls a direction and intensity of light beams generated by light sources, and a method employing a psudo-uniform volumetric image space in which volumetric image elements have a sane size.

The present invention is a widget display system for a volumetric or true three-dimensional (3D) display that provides a volumetric or omni-viewable widget that can be viewed and interacted with from any location around the volumetric display. The widget can be viewed from any location by duplicating the widget such that all locations around the display are within the viewing range of the widget. A widget can be provided with multiple viewing surfaces or faces making the widget omni-directional. A widget can be continuously rotated to face all of the possible locations of users over a period of time. User locations can be determined and the widget can be oriented to face the users when selected.

The present invention is a system that creates a volumetric display and a user controllable volumetric pointer within the volumetric display. The user can point by aiming a beam which is vector, planar or tangent based, positioning a device in three-dimensions in association with the display, touching a digitizing surface of the display enclosure or otherwise inputting position coordinates. The cursor can take a number of different forms including a ray, a point, a volume and a plane. The ray can include a ring, a bead, a segmented wand, a cone and a cylinder. The user designates an input position and the system maps the input position to a 3D cursor position within the volumetric display. The system also determines whether any object has been designated by the cursor by determining whether the object is within a region of influence of the cursor. The system also performs any function activated in association with the designation.

The present invention is a system that allows a user to physically rotate a three-dimensional volumetric display enclosure with a corresponding rotation of the display contents. The rotation of the enclosure is sampled with an encoder and the display is virtually rotated by a computer maintaining the scene by an amount corresponding to the physical rotation before being rendered. This allows the user to remain in one position while viewing different parts of the displayed scene corresponding to different viewpoints. The display contents can be rotated in direct correspondence with the display enclosure or with a gain (positive or negative) that accelerates the rotation of the contents with respect to the physical rotation of the enclosure. Any display widgets in the scene, such as a virtual keyboard, can be maintained stationary with respect to the user while scene contents rotate by applying a negative rotational gain to the widgets. The rotation can also be controlled by a time value such that the rotation continues until a specified time is reached or expires.

The invention relates to a method of manipulating the visibility of image elements on the screens of a multi-screen display. In particular, methods of maximising the visibility of selected target image elements are identified.

The present invention is a novel, high resolution, color, three-dimensional (3-D) volumetric display system for dynamic images—the video cube. The video cube consists of an air-tight glass cube filled with a gas mixture and multiple planes of thin wires arranged in alternating orthogonal layers. These wires may be set at voltage potentials capable of producing a glow discharge at the intersection of pairs of wires. Using a computer capable of storing dynamic image data and electronic controllers capable of energizing pairs of wires appropriately at the proper time 3-D dynamic images may be formed from multiple glows between excited wire pairs. The video cube may be used to display complex real-time information from computers and other digital processors with high accuracy for unlimited number of simultaneous unaided observers.
