Patent number: 10330942Abstract: Techniques are described for designing and manufacturing a surface that produces a desired image when illuminated by a light source. As described, the desired image may be decomposed into a collection of Gaussian kernels (referred to as Gaussians). A shape of a micropatch lens corresponding to each Gaussian may be determined, and the resulting micropatch lenses may be assembled to form a highly continuous surface that will cast an approximation of the desired image formed form the sum of a plurality of Gaussian caustics. The disclosed techniques may be used to create a design for a light-redirecting surface amenable to milling (or other manufacturing process).Type: GrantFiled: October 21, 2015Date of Patent: June 25, 2019Assignee: Disney Enterprises, Inc.Inventors: Marios Papas, Wojciech Jarosz, Wenzel A. Jakob, Szymon M. Rusinkiewicz, Wojciech Matusik, Tim A. Weyrich

Patent number: 9805496Abstract: The disclosure provides an approach for generating virtual terrains. A terrain editing application is configured to receive assets of various types, including a blank canvas, two-dimensional (2D) sketches, real-world elevation maps, authored heightfields, etc. The assets specify characteristics of a terrain, and provide starting points for creating the virtual terrain. The editing application further provides a set of tools allowing a user to modify the virtual terrain. In one embodiment, the set of tools may include a copy-and-paste tool, a peak creation tool, a ridge creation tool, a ridge tracing tool, and a resynthesis tool. The editing application generates a new layer for each edit, as well as 2D and three-dimensional (3D) previews of the edited terrain. The editing application also provides a user-adjustable frequency decomposition of each layer. The editing application combines layers using Laplacian blending to produce the final virtual terrain.Type: GrantFiled: May 27, 2014Date of Patent: October 31, 2017Assignees: Disney Enterprises, Inc., University College LondonInventors: Kenneth Mitchell, Gwyneth Bradbury, Tim Weyrich

Patent number: 7319467Abstract: A face is scanned to obtain a three-dimensional geometry of the face, images are also acquired of the face, and subsurface scattering of the face is measured. A translucency map is determined from the subsurface reflectance. A total surface reflectance and a normal map are estimated from the three-dimensional geometry and the images, and diffuse reflectance is estimated using the total reflectance. An albedo map is determined from the diffuse reflectance. The diffuse reflectance is subtracted from the total reflectance to obtain a surface reflectance. A set of bi-directional reflectance functions is fitted to the surface reflectance. Then, the set of bi-directional reflectance distribution functions, the albedo map, and the translucency map are combined to form a skin reflectance model of the face.Type: GrantFiled: March 29, 2005Date of Patent: January 15, 2008Assignee: Mitsubishi Electric Research Laboratories, Inc.Inventors: Tim Weyrich, Wojciech Matusik, Hanspeter Pfister, Henrik Wann Jensen, Wai Kit Addy Ngan, Markus Gross

Patent number: 7230620Abstract: A method renders a model of an object by first acquiring, in an acquisition space, a reflectance field of the object. The reflectance field includes a set of reflectance images of the object and a point model of the object. The model is deformed in an object space to generate a deformed model. For each point of the deformed model in the object space, the set of the reflectance images is queried in the acquisition space to obtain reflectance coefficients for each point. Each point of the deformed model is then shaded according to the corresponding reflectance coefficients to generate an image of the object reflecting the deforming.Type: GrantFiled: August 5, 2004Date of Patent: June 12, 2007Assignee: Mitsubishi Electric Research Laboratories, Inc.Inventors: Hanspeter Pfister, Tim Weyrich, Markus Gross
