Abstract
An exemplary method for reducing user-perceived scene resolution time to render a node tree in a three-dimensional environment includes identifying a first cache node in the node tree at a first level of detail. The exemplary method also includes computing a first priority score based at least on a depth in the node tree of the first level of detail and a first tile distance. The exemplary method further includes identifying a second cache node in the node tree at a second level of detail different from the first level of detail. The exemplary method also include computing a second priority score based at least on a depth in the node tree of the second level of detail and a second tile distance. The exemplary method further includes ordering cache node requests based at least on the relative values of the first and second priority scores.
