Abstract
In an example method, a computer system accesses first data representing three-dimensional content and a plurality of bounding boxes. Each of the bounding boxes encloses at least a portion of the three-dimensional content. The computer system also access second data representing a viewing frustum for rendering the three-dimensional content. Based on the first and the second data, the computer system identifies a subset of the bounding boxes that are visible according to the viewing frustum. For each of the one or more bounding boxes of the subset, the computer system identifies an image tile from among a plurality of image tiles corresponding to the bounding box, and renders one or more video frames in a frame buffer based on the identified image tile.
