Abstract
Systems and methods for aggregation of textures at multiple resolution levels are described herein. An embodiment includes a preprocessing system that aggregates textures associated with objects of interest at multiple resolution levels. Individual textures may have a 'pyramid' of resolution levels, and aggregated textures may be combined into a 'tree' or a “forest”. Additionally, a texture forest may also be organized spatially and in resolution using the nodes of a quadtree, based on the 3D coordinates of the geometric primitives using each texture. A client identifies a resolution level for each object of interest in an image frame, groups objects based on resolution levels. The client may then test one texture coordinate per object at the beginning of a texture tree, recursively towards each child node of the tree, accumulating texture replacement transforms as a texture matrix. The client may then draw all the textures with the appropriate transform.
