Abstract
A three-dimensional rendering device may project an image on a movable display through a collimating device, which collimates the rays from the display into a narrow solid angle. The narrow solid angle may allow the rays from the display to be projected only to a viewer located at a particular position relative to the display. As the display moves, the information displayed may change to be that appropriate for the particular position, so that a three-dimensional image of the object may be perceived by the viewer as the viewer changes positions around the three-dimensional rendering device.
Claims20
A three-dimensional image rendering device, comprising:
- at least one movable light source displaying different image data as a function of position of the at least one light source;
- and
- at least one array of collimators disposed adjacent to the movable light source, having at least one collimator which collimates light from the light source, and directs rays of light from the light source into a limited cone of illumination which allows the different image data to be viewed from different positions.
A system for rendering a three-dimensional image, comprising:
- a movable display for displaying different image information as a function of position of the display;
- at least one collimating array, which directs light from the display into a limited cone of illumination which allows the different image information to be viewed from different positions adjacent to the display;
- a motor for moving the display through a first and a second predefined distance;
- and
- a controller which directs the display to display first image information while the display is moved through the first predefined distance, and to display second image information while moving the collimator array through the second predefined distance.
A method for rendering a three-dimensional image, comprising:
- displaying first image information from a pixel array through a collimator array while moving the pixel array and collimator array through a first predefined distance;
- and
- displaying second image information through the collimator of the collimator array while moving the pixel array and collimator array through a second predefined distance.
