Abstract
Systems, methods, devices, and non-transitory media of various embodiments enable subdividing large polygon meshes with diverse materials into a hierarchy of separate components, such as tiles. In various embodiments, the components may in aggregate represent the entire mesh. In the hierarchies of separate components as provided by the various embodiments, the components may be loaded as-needed based on importance, culled due to lack of importance to a given view, and/or replaced with higher or lower detail variants depending on importance to a given view. The ability to load components, such as tiles, on-demand provided by the various embodiments may provide improved rendering performance of a large polygon mesh with diverse materials, especially when the rendering leverages data transmission over a network.
