A method and apparatus are provided for printing multicolored three-dimensional objects. The method includes: selectively exposing a photosensitive thermoplastic feedstock to light within an extrusion nozzle, the feedstock comprising a thermoplastic base mixed with a photosensitive material; extruding the exposed feedstock into a deposit to print an object; and photo-chemically developing the deposit to provide color to the deposit. An apparatus is provided for three-dimensional printing with an extrusion nozzle including a light exposing component for selectively exposing the photosensitive thermoplastic feedstock to light within the extrusion nozzle.

Printing multicolored three-dimensional products

A computer-implemented method of creating an artificially tiltable image display from an image containing Z distance values, the method comprising: separating the image into a plurality of layers using the Z distance values; expanding the plurality of layers by a factor dependent on the Z distance values, a layer closer to a viewer being enlarged by a larger factor than a layer further from a viewer, to create information in the layer further from a viewer that is occluded by the layer closer to a viewer; and responsive to a request to tilt the image display, moving the plurality of layers relative to each other so as to display the occluded information.

Artificially tiltable image display

Disclosed embodiments provide techniques for implementation of a photographic effect. An image is acquired while in a zoom configuration. The image is divided into pixel groups. A distance is determined for each group of pixels. The groups of pixels are based on the detected distance of the group of pixels from the camera. The detected distance can be based on the autofocus module within the camera. The detected distance can be a relative distance or an absolute distance. An expansion factor is determined for each group of pixels based on the corresponding determined distance. Expanded pixel groups are created for each pixel group based on the expansion factor. The expanded pixel groups are composited together to create the processed image.
