Patent number: 7339585Abstract: A data processing methodology and corresponding apparatus for visualizing the characteristics of a particular object volume in an overall medical/biological environment receives a source image data set pertaining to the overall environment. First and second contour surfaces within the environment are established which collectively define a target object volume. By way of segmenting, all information pertaining to structures outside the target object volume are excluded from the image data. A visual representation of the target object based on nonexcluded information is displayed. In particular, the method establishes i) the second contour surface through combining both voxel intensities and relative positions among voxel subsets, and ii) a target volume by excluding all data outside the outer surface and inside the inner surface (which allows non-uniform spacing between the first and second contour surfaces). The second contour surface is used as a discriminative for the segmenting.Type: GrantFiled: July 19, 2004Date of Patent: March 4, 2008Assignee: Pie Medical Imaging B.V.Inventors: Boudewijn Joseph Angelus Verstraelen, Sebastiaan Paul Verstraelen

Patent number: 7176917Abstract: A visual programming interface allows an artist to create real time shaders using a tree of shader nodes. Each shader node represents an operation that can be performed in real time through the real time rendering engine. The visual interface allows the arbitrary combinations of these shader nodes to be made and allows the parameters of the shaders to be manipulated or animated. The visual programming interface may be activated in an interactive animation environment through a designation that a real time shader is to be applied to a surface. By integrating the visual programming interface with an interactive animation environment, an artist can experiment readily with different custom real time shaders. An artist also has the flexibility to create arbitrary real time shader trees and to view them interactively without requiring a programmer to develop or modify a custom shader.Type: GrantFiled: August 9, 2002Date of Patent: February 13, 2007Assignee: Avid Technology, Inc.Inventors: Gareth Morgan, Daniel Beaudry, Ian Stewart, Luc Bolduc, Alexandre Jean Claude

Patent number: 6977649Abstract: A system and method for increasing rendering efficiency in pipelined graphics systems. In the disclosed embodiments, reads of pixel information during the rendering of a primitive are suspend if the pixel information has not been updated by a previous primitive. In some embodiments, reads of pixel information are also suspended periodically when a table tracking the information becomes full. In some embodiments a Read Monitor Unit 108 controlled by the graphics system's Memory Controller 106 is used to track pixels which have been affected by rendered primitives. In some embodiments, a history list is used to avoid suspension of reads for antialiased lines. In a particular embodiment, the table used to track affected pixels is two-bits, the first bit tracking whether the pixel has been touched by a primitive since the last SuspendReads command was invoked and the second bit tracking whether the pixel has been touched by the current primitive. Both bits are reset when a power on or SuspendReads command occurs.Type: GrantFiled: March 29, 1999Date of Patent: December 20, 2005Assignee: 3DLABS, Inc.

Patent number: 6956574Abstract: The present invention provides a method for hierarchically decomposing a visual or audio object within an animation into plurality of objects which can be individually edited to achieve particular animation effects. For example, a graphical object may be decomposed into a plurality of graphical sub-objects, each of which is inherits an anchor point from the original object, or is given an original anchor point distinct from the original object. Each sub-object also includes a relative position for the sub-object relative to the anchor point. The path of the anchor point is combined with relative positions of the sub-objects to produce an animation for the object as a whole. This decomposition technique can greatly increase computational efficiency of an animation. It also provides for inheritance of attributes between objects and descendent sub-objects. The objects may support functions, or behaviors, such as morphing or motion blurring.Type: GrantFiled: February 9, 2000Date of Patent: October 18, 2005Assignee: Paceworks, Inc.Inventors: Phillipe Cailloux, Phac Le Tuan, Dan Lipton, Antonio Tuzzi, Jerome Magnier
