Abstract: The device makes 3 dimensional objects. Micro-displays with quick reactant of material enable to produce the 3 dimensional objects very rapidly and with high resolution. Optionally, the 3 dimensional input device is embedded to the system to create the instant duplication of 3 dimensional images/objects. Image can be artificially generated by CAD model. Imaged beams are projected to the materials. The materials react with imaged beams and are hardened, softened or cut according to the desired shape generated by the imaged beam. Image can be projected to the surface of material or inside of the material to generate 3 dimensional object.

Abstract: Color 3D image input device (digitizer) and 3D image output device (display) that captures and show 3D images having the light fields. Direction-position-color of the light fields are controlled by various methods such as liquid crystal masks with photo-sensors, liquid crystal masks with color-image-emitter. Alternatively, micro-lens-array, micro-pinholes, liquid crystal pinholes, varifocal micro-lens arrays and varifocal index-gradient lens, etc. are used together with high-resolution and high-speed pattern-generating means with photo-sensors and photo-emitters. This can be used for 3D communication, 3DTV, 3D camera, cloaking device.

Abstract: Color 3D image display devices that show realistic 3D images using the virtual light points fields. Color-intensity and directions of the virtual light points fields are controlled by various methods such as selection of directions of properly color-intensified light rays. For such methods, micro-pinholes, liquid crystal pinholes, varifocal micro-lens arrays and varifocal index-gradient lens, etc. are used together with high-resolution and high-speed 2 dimensional pattern-generating displays. By adding linear (reciprocating) and/or rotational motion to such 3D display makes higher resolution and view angles wider.
