Abstract: A display system for presenting a holographic image to a viewer may comprise a coherent light source, a display element, and a computing device operatively connected to the coherent light source and the display element, the coherent light source emitting a light that enters the display element from the same side of the viewer, and the display element comprising a liquid crystal layer and a partially-transmissive-partially-reflective layer, wherein the computing device is configured to provide a control signal to the display element to present the holographic image, wherein the liquid crystal layer receives light from the light source and is controlled by the control signal to modulate a phase of the light from the light source, and wherein the partially-transmissive-partially-reflective layer receives light from the liquid crystal layer and reflects the light back through the liquid crystal layer to the viewer.

Abstract: A 3D model system is configured to validate and optimize for 3D printing an unprocessed 3D model described by an input data file. The 3D model system is configured to detect printability issues associated with the unprocessed 3D model and automatically address these issues. Such issues can include boundary edges, non-manifold geometries, structural deficiencies, etc. Upon resolving these issues, the 3D model can be optimized for 3D printing. Optimizations can include hollowing to reduce printing cost and exterior surface smoothing. The resulting validated and optimized 3D model can be converted into an output data file which can be an input to a 3D printer or a 3D printing service for printing the object depicted by the 3D model. The 3D model system can operate as a network or cloud-based service. Users are able to interact with the 3D model system using a series of web-based user interfaces.

Abstract: Methods, systems, and devices for up-scaling a source input video from a lower, first resolution to a desired output video having a higher, second resolution, using fractal zooming techniques to replace each individual source pixel of each respective frame of the source input video with a multiple of proposed replacement pixels in the vertical and horizontal dimensions having similar characteristics as the individual source pixel, reducing noise associated with each respective frame of the desired output video, re-sizing, as necessary, each respective replacement frame to the second resolution, and outputting each zoomed replacement frame to generate the desired output video having a higher, second resolution, which is the up-scaled version of the source video. The fractal zooming techniques include identifying a plurality of candidate pixels from the source video and selecting a group of pixels from the candidate pixels that best matches the individual source pixel.
