Techniques are disclosed for systems and methods to provide relatively accurate position data from a plurality of separate position sensors. A system includes a logic device configured to first and second position sensors each coupled to a mobile structure at respective first and second locations. The logic device is configured to receive position data corresponding to a position of the mobile structure from the position sensors, determine weighting factors corresponding to the received position data, and determine a measured position for the mobile structure based, at least in part, on the received position data and the determined weighting factors.

A processor receives sensor feedback indicating a focal point of an HMD user. The processor casts rays through an image volume based on the sensor feedback. Each of the rays is associated with a pixel of a rendered image. The rendered image has a first plurality of pixels associated with the rays and a second plurality of unassociated pixels. The rays comprise a first portion cast at or near the focal point and a second portion that is cast farther away from the focal point. A first spacing between rays of the first portion is less than a second spacing between rays of the second portion. The processor determines color values corresponding with each of the first plurality of pixels associated with the rays. The processor determines color values corresponding with each of the second plurality of unassociated pixels of the rendered image. The HMD displays the rendered image.
