Patent number: 8610729Abstract: A floating point rasterization and frame buffer in a computer system graphics program. The rasterization, fog, lighting, texturing, blending, and antialiasing processes operate on floating point values. In one embodiment, a 16-bit floating point format consisting of one sign bit, ten mantissa bits, and five exponent bits (s10e5), is used to optimize the range and precision afforded by the 16 available bits of information. In other embodiments, the floating point format can be defined in the manner preferred in order to achieve a desired range and precision of the data stored in the frame buffer. The final floating point values corresponding to pixel attributes are stored in a frame buffer and eventually read and drawn for display. The graphics program can operate directly on the data in the frame buffer without losing any of the desired range and precision of the data.Type: GrantFiled: June 12, 2012Date of Patent: December 17, 2013Assignee: Graphic Properties Holdings, Inc.Inventors: John M.

Publication number: 20130069963Abstract: This application describes a system that captures 3D geometry commands from a first 3D graphics process and stores them in a shared memory. A second 3D environment process creates a 3D display environment using a display and display hardware. A third process obtains the 3D commands and supplies them to the hardware to place 3D objects in the 3D environment. The result is a fused display environment where 3D objects are displayed along with other display elements. Input events in the environment are analyzed and mapped to the 3D graphics process or the environment where they affect corresponding processing.Type: ApplicationFiled: November 15, 2012Publication date: March 21, 2013Applicant: Graphics Properties Holdings, Inc.Inventor: Graphics Properties Holdings, Inc.

Patent number: 8253734Abstract: The present invention is a system that grids original data, maps the data at the grid locations to height values at corresponding landscape image pixel locations and renders the landscape pixels into a three-dimensional (3D) landscape image. The landscape pixels can have arbitrary shapes and can be augmented with additional 3D information from the original data, such as an offset providing additional information, or generated from processing of the original data, such as to alert when a threshold is exceeded, or added for other purposes such as to point out a feature. The pixels can also convey additional information from the original data using other pixel characteristics such as texture, color, transparency, etc.Type: GrantFiled: July 23, 2010Date of Patent: August 28, 2012Assignee: Graphics Properties Holdings, Inc.Inventor: David William Hughes

Patent number: 8194083Abstract: A plurality of vertex or fragment processors on a graphics processor perform computations. Each vertex or fragment processor is capable of executing a separate program to compute a specific result. A combiner manages the combination of the results from the respective processors, and produces a final transformed vertex or pixel value. The vertex or fragment processors and the combiner can be programmable to modify their operations. As such, the vertex or fragment processors can operate in a parallel or serial configuration, or both. The combiner manages and resolves the operations of the serial and/or parallel configurations. A synchronization barrier enables the combiner to perform data-dependency analysis to determine the timing and ordering of the respective processors' execution. A transformation module can include one or more programmable vertex processors that transforms three-dimensional geometric data into fragments.Type: GrantFiled: November 8, 2010Date of Patent: June 5, 2012Assignee: Graphics Properties Holdings, Inc.Inventor: David Shreiner

Patent number: 8169441Abstract: A method and system for minimizing an amount of data needed to test data against subarea boundaries in spatially composited digital video is provided. Graphics data for a frame is composed of geometry chunks. Each geometry chunk is defined by its own bounding region, where the bounding region defines the space the geometry chunk occupies on the compositing window. Only the parameters that define the bounding region are communicated to each graphics unit in conjunction with the determination of which graphics unit will render the geometry chunk defined by the bounding region. The actual graphics data that comprises the geometry chunk is communicated only to those geometry units that will actually render the geometry chunk. This reduces the amount of data needed to communicate graphics data information in spatially composited digital video.Type: GrantFiled: April 11, 2011Date of Patent: May 1, 2012Assignee: Graphics Properties Holdings, Inc.Inventors: David R.

Patent number: 8135212Abstract: Methods and apparatus for generating composite images for displays are provided. For some embodiments, ray tracing algorithms may be utilized to efficiently generate a composite image corresponding to multiple views. Because ray tracing is done on a per pixel basis, it is possible to generate pixel values for only those pixels that will be allocated to a particular image view. By tracing rays from a viewpoint only through those pixels allocated to displaying images corresponding to that viewpoint, a composite image may be generated without discarding pixel data.Type: GrantFiled: April 11, 2011Date of Patent: March 13, 2012Assignee: Graphics Properties Holdings, Inc.Inventor: Charles C.
