WebFeb 3, 2011 · Novel highly symmetric multi-faceted polyhedral Cu 2 O crystals enclosed by controllable high-index facets and different low-index facets have been synthesized via a template-free complex-precursor solution route. The formation and evolution of these polyhedral shapes can be attributed to the aggregation and ripening mechanism with face … Web(2) Based on the structural characteristics of a building, incorrect topological connections of thin-plate planes are corrected, and the lamellar structure is recovered. (3) Optimization based on corner point clumps reduces redundant corner points and improves the realism of a polyhedral building model.
