Patent number: 10607404Abstract: The present invention relates to a glossy part of radiation is estimated coming from a surface illuminated by area light source(s) having source surface(s) (A) bounded by edge curves, by determining integrand function(s) representative of that glossy part. The latter corresponding to an integration of the integrand function along the edge curves.

Patent number: 10339703Abstract: Shadow is computed in a lighted 3D scene, based on a depth map. For each depth map element, following geometric information is stored: depth value, coordinates of vertices and local depth variation of a surface element. Also, ray intersection is tested for a pixel with the surface element having depth computed from the depth and local depth variation, taking into account the coordinates of vertices. A minimum depth associated with the surface element is further computed from the geometric information, with which the depth of a pixel is compared. The pixel is classified as lit if the depth is lower than the minimum depth, and as shadowed if the depth is greater and if a ray intersection is found for the pixel with the surface element from the ray intersection testing. The invention can provide a fast solution for high-quality shadow.Type: GrantFiled: November 11, 2015Date of Patent: July 2, 2019Assignee: Vidon Patents and StrategyInventors: Pascal Lecocq, Jean-Eudes Marvie, Arthur Dufay

For each spherical edge UiUi+1 of a projected area consisting in a projection of the light source onto a unit sphere centered on the shading point, a local radiance is established by: establishing a normalized projection vector S of the viewing reflection vector onto a plane defined by edge UiUi+1 and the shading point determining if point S associated with vector S lies inside UiUi+1, and if so, performing a halfway transform of Ui; S and Ui+1 and an edge integral on Ui; S and S, Ui+1. An iteration is performed over all edges and the local radiance is summed, the surface being rendered accordingly.Type: ApplicationFiled: August 4, 2016Publication date: August 9, 2018Inventors: Pascal LECOCQ, Jean-Eudes MARVIE, Francois-Louis TARIOLLE

Publication number: 20180174354Abstract: A 3D scene illuminated by light sources is rendered on an image grid by path tracing. At least one ray originating from each grid pixel is traced in the 3D scene until it meets an object at a crossing point, that ray is bounced towards one of the light sources, a visibility test is made for that ray between the crossing point and that light source, and a contribution of that light ray is added at the crossing point in carrying out the rendering at the concerned pixel. The visibility tests are carried out over the pixels in a clustered way according to the light sources, the visibility tests being clustered in terms of computations and/or of memory storage in function of the light sources respectively associated with the visibility tests.Type: ApplicationFiled: December 20, 2017Publication date: June 21, 2018Inventors: Arthur DUFAY, Pascal Lecocq, Jean-Eudes Marvie

Publication number: 20180005427Abstract: Elementary geometries for rendering objects of a 3D scene are generated from input geometry data sets. Instructions of a source program are transformed into a code executable in a rendering pipeline by at least one graphics processor, by segmenting the source program into sub-programs, each adapted to process the input data sets, and by ordering the sub-programs in function of the instructions. Each ordered sub-program is configured in the executable code for being executed only after the preceding sub-program has been executed for all input data sets. Launching the execution of instructions to generate elementary geometries includes determining among the sub-programs a starting sub-program, deactivating all sub-programs preceding it and activating it as well as all sub-programs following it. Modularity is thereby introduced in generating elementary geometries, allowing time-efficient lazy execution of grammar rules.Type: ApplicationFiled: October 24, 2015Publication date: January 4, 2018Inventors: Jean-Eudes MARVIE, Alex REPAIN, Patrice HIRTZLIN

Patent number: 9830491Abstract: A particular implementation selects two or more fiducial markers to be embedded into a video to convey information. Specifically, the translation, scaling and rotation between a reference marker and a secondary marker can be used to transmit information. When more information needs to be embedded, more secondary markers can be used. The transformation between the fiducial markers can also evolve over time as the information to be embedded evolves over time. At the receiving side, a reader device captures a video including multiple fiducial markers and determines the translation, scaling and rotation between the fiducial markers. Based on the transformation of the fiducial markers, the reader device can retrieve the information embedded in the captured video by the fiducial markers.Type: GrantFiled: August 2, 2016Date of Patent: November 28, 2017Assignee: THOMSON LicensingInventors: Anthony Laurent, Bernard Denis, Jean-Eudes Marvie, Eric Hubert
