Abstract: One embodiment of the present invention sets forth a method for dynamically load balancing rendering operations across an IGPU and a DGPU. For each frame, the graphics driver configures the IGPU to pre-compute Z-values for a portion of the display surface and to write feedback data to the system memory indicating the time that the IGPU used to process the frame. The graphics driver then configures the DGPU to use the pre-computed Z-values while rendering to the complete display surface and to write feedback data to the system memory indicating the time that the DGPU used to process the frame. The graphics driver uses the feedback data from the IGPU and DGPU in conjunction with the percentage of the display surface that the IGPU Z-rendered for the frame to scale the portion of the display surface that the IGPU Z-renders for one or more subsequent frames. In this fashion, overall processing within the graphics pipeline is optimized across the IGPU and DGPU.

Abstract: A method, apparatus, and computer readable storage medium provides the ability to stabilize a series of two or more still images (i.e., a clip). The clip of image data is obtained. The clip is then analyzed to produce a set of source curves that represent a global movement detected in the clip. Each of the source curves is filtered to compute result curves. The source and result curves are then exposed and displayed to the user who may modify/tweak the curves as desired. Automatically, without additional user input, and without reanalyzing the original clip, the result curves are recomputed based on the user's changes. The original clip is then transformed into a result clip/series based on the source and result curves.

Abstract: The general field of the invention relates to the binocular helmet-mounted display devices worn by aircraft pilots. In night use, one of the drawbacks of this type of device is that the uprights of the cockpit introduce significant visual masks into the field of the optical sensors. The method according to the invention is a method for eliminating these masks in the images presented to the pilot by graphics processing of the binocular images. It relies on the fact that, given the parallax, the uprights occupy, in two images from the left and right sensors, different positions. The comparison of the two images makes it possible to identify, and then eliminate, these masks, and finally to replace them with parts of images of the outside landscape.

In respect of the eye-plane, the need for clipping is avoided by modifying edge equations generated for a primitive in dependence on the sign of a “W” value for each vertex of the primitive.
