1. A method for displaying virtual or augmented reality, comprising: capturing at least one parameter associated with ambient light in an environment; identifying a first light map corresponding to one or more first light map parameters and a second light map corresponding to one or more second light map parameters based at least in part on at least one parameter, wherein a light map includes a geometric space and models light information of virtual content and the environment in which a user is located; identifying one or more errors in one or more light map parameters of the one or more first light map parameters or the one or more second light map parameters based in part or in whole upon the at least one parameter associated with ambient light and; constructing and storing a new light map in a library comprising the first light map and the second light map at least by combining the one or more first light map parameters respectively with the one or more second light map parameters into one or more corresponding combined parameters and by modifying at least one image generation characteristic of a virtual or augmented reality system to reduce the one or more errors in the one or more light map parameters; modifying the virtual content to be presented to a user based at least in part on the new light map; and projecting light associated with the virtual content that has been modified.
