Abstract
A desktop based projector screen having an inner concave display surface upon which a video image or a series of images is projected with a sense of realism comparable with natural viewing of three-dimensional physical reality. The viewing surface combines three concave sections which are derived from solid figures including a dome, cylinder and a plane.
Claims7
A multi-section hybrid projection screen positionable on a desktop, said hybrid screen having a concave three-dimensional (3D) viewing surface for receiving focused images projected on said concave surface, said hybrid screen comprising:
- a) a concave semidome ceiling section;
- b) a flat semicircular floor section having a diameter matching the maximum diameter of said semidome;
- and
- c) a semicylindrical wall section having a diameter matching the maximum diameter of said semidome, said wall section being edgewise joined between said ceiling section and said floor section to form a continuous concave viewing surface with said ceiling section and said wall section, and wherein said ceiling section is supported above said desktop when said floor section is positioned on said desktop;
- and
- d) wherein said multi-section hybrid screen displays images projected on at least a subsection of said hybrid screen.
Apparatus for viewing a three-dimensional object comprising:
- a multi-section hybrid projection screen positionable on a desktop, said hybrid screen having a generally concave three-dimensional (3D) viewing surface for receiving focused images projected on said concave surface, said hybrid screen comprising:
- a) a concave semidome ceiling section;
- b) a flat semicircular floor section having a diameter matching the maximum diameter of said semidome;
- and
- c) a semicylindrical wall section having a diameter matching the maximum diameter of said semidome, said wall section being edgewise joined between said ceiling section and said floor section to form a continuous concave viewing surface with said ceiling section and said wall section, and wherein said ceiling section is supported above said desktop when said floor section is positioned on said desktop;
- and
- d) at least one video projector for projecting focused images on at least a subsection of said hybrid screen.
