Abstract: Systems are configured for facilitating light leak correction for a display device. The systems are configured to obtain a color value for a pixel and obtain a light leak value associated with the pixel. The light leak value is based on a measured light leakage associated with a color filter of a display device configured to display the pixel. Systems are also configured to generate an updated color value for the pixel by applying a light leak compensation operation to the color value for the pixel. The light leak compensation operation uses the light leak value as an input for modifying the color value to compensate for light leakage that may otherwise occur when displaying the pixel on the display device. Systems are also configured to trigger display of the pixel on the display device using the updated color value.

Abstract: Sensory feedback (“chaperoning”) systems and methods for guiding users in virtual/augmented reality environments such as walk-around virtual reality environments are described. Exemplary implementations assist with preventing collisions with objects in the physical operating space in which the user acts, among other potential functions and/or uses.

Abstract: A method and apparatus for performing tessellation lighting operations for video graphics primitives in a video graphics system is presented. When the vertex parameters corresponding to the vertices of a video graphics primitive are received, a tessellation operation is performed such that a number of component primitives are generated. The vertex parameters corresponding to the vertices of the component primitives are then calculated utilizing the vertex parameters for the original video graphics primitive. Such calculation operations include determining a corresponding normal vector for each component primitive vertex. Each of the component primitives is then individually processed. Such processing may include calculating the lighting effects for each component primitive and performing additional processing operations that generate pixel fragments for the primitive.

Abstract: A method and apparatus for processing non-planar video graphics primitives is presented. Vertex parameters corresponding to vertices of a video graphics primitive are received, where the video graphics primitive is a non-planar, or higher-order, video graphics primitive. A cubic Bezier control mesh is calculated using the vertex parameters provided for the non-planar video graphics primitive. Two techniques for calculating control points included in the cubic Bezier control mesh along the edges of the non-planar video graphics primitive are described. The central control point is determined based on the average of a set of reflected vertices, where each of the reflected vertices is a vertex of the non-planar video graphics primitive reflected through a line defined by a pair of control points corresponding to the vertex.
