Patent number: 9858708Abstract: In one example, a graphic computing device may apply a clipping technique to accurately and efficiently render a graphic data set. A central processing unit may generate a convex polygonal clip from a two-dimensional polygon. The central processing unit may calculate a clipping plane for a convex polygonal clip based on an edge of the convex polygonal clip. A graphics processor may apply the convex polygonal clip in a pixel shader.Type: GrantFiled: September 10, 2014Date of Patent: January 2, 2018Assignee: Microsoft Technology Licensing, LLCInventors: Miles Cohen, Meng Yang, Amar Patel, Leonardo Blanco

Patent number: 9779528Abstract: In one example, a graphics processing unit may use an optimized geometric realization to render a text shape as a scalable geometry. The graphics processing unit may generate an inner geometry for a text shape. The graphics processing unit also may generate a tessellated edge geometry abutting the inner geometry for an edge of the text shape. The graphics processing unit further may assign a coverage gradient to the tessellated edge geometry to create an anti-aliased edge for the text shape.Type: GrantFiled: September 12, 2014Date of Patent: October 3, 2017Assignee: Microsoft Technology Licensing, LLCInventors: Miles Cohen, Anthony John Rolls Hodsdon

Patent number: 8659589Abstract: Methods and computer-readable media for displaying two-dimensional objects on a display device are disclosed. Rendering requests are received from an application to render two-dimensionally modeled graphics to a display device. Primitive geometries of drawing calls of the rendering requests are tessellated into sequences of triangles. The vertices of the triangles are mapped to a vertex buffer along with an index to identify associated constant data. Batching operations store and communicate calls and mapped data to a graphics processing unit by way of a three-dimensional rendering application program interface. Constant data associated with the mapped data are indexed and appended together in a constant buffer, thereby allowing drawing calls to be coalesced. A staging buffer and a staging texture are provided for batching text anti-aliasing operations. Shader fragments are precompiled and organized by way of a predetermined lookup table.Type: GrantFiled: December 3, 2012Date of Patent: February 25, 2014Assignee: Microsoft CorporationInventors: Mark Lawrence, Alexander Stevenson, Thomas Olsen, Ben Constable, Chris Raubacher, Miles Cohen, Bilgem Cakir, Robert Brown, Brett Bloomquist, Chris Kam Ming Chui, Samrach Tun, Jason Hartman, Kanwal Vedbrat, Andrew Precious, Thomas Mulcahy

Publication number: 20070013712Abstract: Systems and methods are disclosed for providing texture tiling. The disclosed systems and methods may include copying a source image into a texture of a size the same or larger than the source image. Furthermore, the disclosed systems and methods may include displacing texture coordinates corresponding to the texture into a desired range. A displacement map may be used in displacing the texture coordinates. Moreover, the disclosed systems and methods may include rendering, within the desired range, an output image corresponding to the texture coordinates associated with the texture.Type: ApplicationFiled: July 15, 2005Publication date: January 18, 2007Applicant: Microsoft CorporationInventors: Miles Cohen, Christopher Raubacher, Jason Hartman
