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, devices, and implementing technologies for up-scaling an original source video from a lower, first resolution to a desired output video having a higher, second resolution, using fractal zooming techniques to replace individual source pixels in each respective image frame of the original source video with a plurality 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, which is an up-scaled version of the original source video. The quality of the up-scaled output video is improved by using artifact filtering and linear smoothing techniques after the initial search and replace steps of the fractal zooming process.
