摘要:
An image generator takes graphical objects and an occlusion relationship for the objects and resolves non-binary occlusion cycles with image compositing operations to produce an output image of the objects. The image generator takes an occlusion relationship for objects in a scene and a set of antialiased image layers with transparency of the objects and produces an antialiased image of the objects with hidden surfaces eliminated. One implementation operates on subsets of the objects in a scene that form non-binary cycles. This implementation uses a chain of atop operators to combine occluding objects with a selected object from a subset, and then combines this result with other objects in the cycle using over image operations. Another implementation computes a chain of out image operations for each object to combine the image layers of the occluding objects with the image layer of the object. The results of each chain of out image operations are summed to produce an output image.

A layered graphics rendering pipeline for real time 3D animation independently renders terms in a shading model to separate image layers. The layered pipeline factors the shading model into separate image layers and renders geometry to these layers independently. Each layer can have an independent update rate and a spatial resolution different than the resolution of the output images. A compositor that supports one or more image operators composites the factored layers into an output image to generate frames of animation. To reduce rendering overhead, factored terms can be rendered once and then re-used in later frames by warping the initial rendering.

A layered graphics rendering pipeline measures image fidelity ("fiducials") to determine how accurately a transformed image layer approximates a rendering of a 3D object. The graphics rendering pipeline approximates the change in position or color of 3D object by transforming a rendering of the 3D object from a previous frame. The pipeline uses the fiducials to control rendering of factored scene elements to independent image layers. The pipeline then combines the layers to compute frames of animation. The types of fiducials include sampling, visibility, and photometric fiducials. The sampling fiducial measures the distortion of an image sample when warped to screen coordinates. The visibility fiducial measures the change in visibility of a scene element since a previous rendering of the scene element. The photometric fiducial measures either the change in lighting from the time of the previous rendering to the current time, or it measures the difference between warped color samples and actual color samples of the scene element for a current frame.

The present invention is a field effect transistor having a strained semiconductor substrate and Schottky-barrier source and drain electrodes, and a method for making the transistor. The bulk charge carrier transport characteristic of the Schottky barrier field effect transistor minimizes carrier surface scattering, which enables the strained substrate to provide improved power and speed performance characteristics in this device, as compared to conventional devices.

A MOSFET device and method of fabricating are disclosed. The present invention utilizes Schottky barrier contacts for source and/or drain contact fabrication within the context of a MOSFET device structure to eliminate the requirement for halo/pocket implants and shallow source/drain extensions to control short channel effects. Additionally, the present invention unconditionally eliminates the parasitic bipolar gain associated with MOSFET fabrication, reduces manufacturing costs, tightens control of device performance parameters, and provides for superior device characteristics as compared to the prior art.

A dense guide image or signal is used to inform the reconstruction of a target image from a sparse set of target points. The guide image and the set of target points are assumed to be derived from a same real world subject or scene. Potential discontinuities (e.g., tears, edges, gaps, etc.) are first detected in the guide image. The potential discontinuities may be borders of Voronoi regions, perhaps computed using a distance in data space (e.g., color space). The discontinuities and sparse set of points are used to reconstruct the target image. Specifically, pixels of the target image may be interpolated smoothly between neighboring target points, but where neighboring target points are separated by a discontinuity, the interpolation may jump abruptly (e.g., by adjusting or influencing relaxation) at the discontinuity. The target points may be used to select only a subset of the discontinuities to be used during reconstruction.

Systems, methods, and computer-readable media provide for the creation of a template-based targeted marketing presentation. According to various embodiments described herein, a sales representative utilizes a workstation to request a marketing presentation for a certain category of customer within a particular market. A presentation engine retrieves applicable up-to-date data corresponding to the customer category and market from a database and uses the data to make one or more Return On Investment (ROI) calculations. One or more presentation templates include data insertion locations. The one or more ROI calculations and other retrieved data is used to populate the data insertion locations of a selected presentation template. Once populated, the resulting marketing presentation is customized with targeted data and statistics for presenting to the customer.

A waveguide device is provided comprising an optical waveguide core and a cladding optically coupled to the optical waveguide core. The cladding comprises an optically functional region defining a refractive index that is configured to vary in response to a control signal applied to the optically functional region. The refractive index of the optically functional region is lower than the refractive index of the optical waveguide core. In accordance with one embodiment of the present invention, the optically functional region may be characterized as a Kerr Effect medium.
