1. A method comprising:
at an electronic device having a processor:
rendering a first view for a first viewpoint of a three-dimensional (3D) environment;
estimating differences between the first view and a second view for a second viewpoint of the 3D environment based on determining one or more disparity indicative characteristics for one or more regions of the first view, wherein determining the one or more disparity indicative characteristics for the one or more regions of the first view comprises:
identifying one or more objects corresponding to each region of the one or more regions;
determining a distance from the electronic device to each of the one or more objects; and
determining a disparity indicative characteristic for the one or more regions corresponding to amounts of expected difference between the one or more regions of the first view and corresponding one or more regions of a potential rendering of the second view based on the determined distance from the electronic device to each of the one or more objects and a threshold; and
based on the estimated differences, rendering the second view for the second viewpoint.
