Techniques for efficiently managing and rendering graphical primitives in three-dimensional (3D) objects are disclosed. A surface of a 3D object is partitioned into a plurality of clusters, each containing a quantity of graphical primitives. Each cluster is mapped to a respective virtual space, which is then hierarchically partitioned into multiple regions. Partition information for the respective virtual space is encoded based on the hierarchical partitioning, and the surface of the 3D object is rendered for display based on the encoded partition information.
