Abstract
Systems and methods for implementing radial density masking graphics rendering for use in applications such as head mounted displays ('HMDs') are described. Exemplary algorithms are disclosed, according to which image resolution varies within an image depending on the distance of a particular point on the image from one or more fixation points. Reconstruction algorithms according to certain embodiments include three stages: (1) hole filling; (2) cross-cell blending; and (3) Gaussian blur.
