Publication number: 20240013497Abstract: A computing system and method can be used to render a 3D shape from one or more images. In particular, the present disclosure provides a general pipeline for learning articulated shape reconstruction from images (LASR). The pipeline can reconstruct rigid or nonrigid 3D shapes. In particular, the pipeline can automatically decompose non-rigidly deforming shapes into rigid motions near rigid-bones. This pipeline incorporates an analysis-by-synthesis strategy and forward-renders silhouette, optical flow, and color images which can be compared against the video observations to adjust the internal parameters of the model. By inverting a rendering pipeline and incorporating optical flow, the pipeline can recover a mesh of a 3D model from the one or more images input by a user.Type: ApplicationFiled: December 21, 2020Publication date: January 11, 2024Inventors: Deqing Sun, Varun Jampani, Gengshan Yang, Daniel Vlasic, Huiwen Chang, Forrester H. Cole, Ce Liu, William Tafel Freeman

Publication number: 20230298269Abstract: Systems and methods of the present disclosure are directed to a method that can include obtaining a 3D mesh comprising polygons and texture/shading data. The method can include rasterizing the 3D mesh to obtain a 2D raster comprising pixels and coordinates respectively associated with a subset of pixels. The method can include determining an initial color value for the subset of pixels based on the coordinates of the pixel and the associated shading/texture data. The method can include constructing a splat at the coordinates of a respective pixel. The method can include determining an updated color value for a respective pixel based on a weighting of the subset of splats to generate a 2D rendering of the 3D mesh based on the coordinates of a pixel and a splat.Type: ApplicationFiled: August 31, 2020Publication date: September 21, 2023Inventors: Kyle Adam Genova, Daniel Vlasic, Forrester H.

Patent number: 11170134Abstract: Disclosed is a parametric feature-based 3D CAD system that allows multiple users to simultaneously edit a parametric feature-based 3D CAD model consisting of 3D parts and assemblies of those parts (3D Model). Several CAD users, each using their own computer, phone, or tablet, can edit the same 3D Model at the same time. Editing may be separate and simultaneous—there is no need for users to worry about locking, checking out, or otherwise restricting each other's access to 3D Models. As a result, users see each other's changes occur in real-time, and may also identify what aspects other users are actively modifying through visible Collaboration Cues.Type: GrantFiled: September 13, 2019Date of Patent: November 9, 2021Assignee: PTC Inc.Inventors: Paul R. Chastell, Daniel Vlasic

Publication number: 20210259551Abstract: A balloon membrane may be coupled with a scanner to produce a three-dimensional representation. The balloon membrane may include an exterior surface, and an interior surface comprising one or more fiducial markers having geometric features to form a random pattern that when detected by the scanner permits a processor of the scanner to use portions of the random pattern present in at least two image frames to align the at least two image frames to form the three-dimensional representation.Type: ApplicationFiled: February 11, 2021Publication date: August 26, 2021Inventors: Alison M. Forsyth, Daniel Vlasic, Ben Frantzdale, Alban de Brouchoven de Bergeyck, Xiaowei Chen, Manas Menon, Federico Frigerio

Publication number: 20170220241Abstract: This solution addresses problems using force touch features on mobile, tablet, or other touch-screen devices by zooming based on the force applied to an area for selection. Zoom may be proportional to force amount, and may be restricted to one direction zoom (zoom-in only). The entire display may be zoomed to maximize effective selection. A selection is made by positioning the finger (or a related selection tool) on the desired target. The selection is retained the instant the user releases the force (lifts finger), at which time the zoom is reverted to the original (non-zoom) level. The one-direction only zoom and instant return avoids re-introducing selection confusion (such as auto-snapping to an undesired target) that may occur with a gradual zoom out.Type: ApplicationFiled: January 27, 2017Publication date: August 3, 2017Inventors: Rammohan Vangapalli, Daniel Vlasic

Patent number: 9448061Abstract: The attenuation and other optical properties of a medium are exploited to measure a thickness of the medium between a sensor and a target surface. Disclosed herein are various mediums, arrangements of hardware, and processing techniques that can be used to capture these thickness measurements and obtain dynamic three-dimensional images of the target surface in a variety of imaging contexts. This includes general techniques for imaging interior/concave surfaces as well as exterior/convex surfaces, as well as specific adaptations of these techniques to imaging ear canals, human dentition, and so forth.Type: GrantFiled: January 22, 2013Date of Patent: September 20, 2016Assignee: Massachusetts Institute of TechnologyInventors: Douglas P.
