Patent number: 7884820Abstract: Interactive relighting with dynamic reflectance involves relighting a graphical scene with dynamic changes to the reflectance(s) in the graphical scene. A graphical scene may include source radiance, regions having reflectances, a surface spot, incident radiation from the source radiance at the surface sport, an incident direction, a viewing direction, exit radiance, and so forth. In an example embodiment, a graphical scene is relighted based on at least one adjusted reflectance of the graphical scene using an incident radiance at a surface spot that is separated into respective incident radiance components corresponding to different respective numbers of interreflections in the graphical scene. In another example embodiment, a graphical scene is relighted based on at least one adjusted reflectance of the graphical scene using a tensor representation for a reflectance of a surface spot with the tensor representation being segmented into three adjustable factors for lighting, viewing, and reflectance.Type: GrantFiled: June 15, 2007Date of Patent: February 8, 2011Assignee: Micorsoft CorporationInventors: Kun Zhou, Yanyun Chen, Stephen S. Lin, Baining Guo

Patent number: 7430490Abstract: A method and system for implementing capturing and rendering geometric details for mesostructure surfaces is described herein. A mesostructure distance function is defined as a function of a given reference point and a given viewing direction. A distance from a reference point to a mesostructure surface point along a viewing direction is measured using the mesostructure distance function. This distance is used to determine the visibility of mesostructure surface for rendering silhouettes. The lighting visibility of the mesostructure surface point may also be determined and used for determining whether the mesostructure surface point is in shadow. This determination may then be used for rendering shadow silhouettes.Type: GrantFiled: March 29, 2006Date of Patent: September 30, 2008Assignee: Microsoft CorporationInventors: Xin Tong, Yanyun Chen, Baining Guo, Heung-Yeung Shum, Jiaping Wang, John Michael Snyder

Patent number: 7327365Abstract: Techniques are provided for at least modeling any one of mesostructure shadowing, masking, interreflection and silhouettes on a surface, as well as subsurface scattering within a non-homogeneous volume. Such techniques include, at least, acquiring material parameters for a material sample, determining irradiance distribution values for the material sample, synthesizing the material sample onto a mesh of an object. The synthesized object may then be rendered by one of plural rendering techniques.Type: GrantFiled: July 23, 2004Date of Patent: February 5, 2008Assignee: Microsoft CorporationInventors: Yanyun Chen, Xin Tong, Stephen S.

Patent number: 7167177Abstract: A method and system for efficient synthesis of photorealistic free-form knitwear, where a single cross-section of yarn serves as the basic primitive for modeling entire articles of knitwear. This primitive, called the lumislice, describes radiance from a yarn cross-section based on fine-level interactions, including occlusion, shadowing, and multiple scattering, among yarn fibers. By representing yarn as a sequence of identical but rotated cross-sections, the lumislice can effectively propagate local microstructure over arbitrary stitch patterns and knitwear shapes. This framework accommodates varying levels of detail and capitalizes on hardware-assisted transparency blending. To further enhance realism, a technique for generating soft shadows from yarn is also introduced.Type: GrantFiled: February 24, 2005Date of Patent: January 23, 2007Assignee: Microsoft CorporationInventors: Baining Guo, Stephen S. Lin, Heung-Yeung Shum, Ying-Qing Xu, Yanyun Chen

Patent number: 7164424Abstract: A system and process for adding a photorealistic rendering of a body of water to a virtual 3D scene or image and creating a video therefrom having interactive water effects. A region of water is added to an image by adding an area depicting the original scene as it would appear if reflected by still body of water. Then, the appearance of the added water region is distorted over a series of image frames in such a way as to simulate how the reflected scene would look if the surface of the water were in motion. The water can have dynamic waves and the user can interact with the water in numbers of ways, including generating ripples on the water surface and creating rain. In addition, these effects can be achieved at full screen resolution with the use of the latest graphics hardware by employing a texture shifting technique.Type: GrantFiled: April 22, 2005Date of Patent: January 16, 2007Assignee: Microsoft CorporationInventors: Lin Liang, Yanyun Chen, Ying-Qing Xu, Baining Guo, Heung-Yeung Shum
