摘要: In this paper we survey some of the major data structures for encoding Level Of Detail (LOD) models. We classify LOD according to dimensionality basic structural element they represent into point-, triangle-, and tetrahedron-based structures. Within each class will review single-level structures, general models based on irregular meshes as well more specialised that assume a certain (semi-) regularity data.
