document: Topology-reducing surface simplification using a discrete solid representation This paper presents a new approach for generating coarse-level approximations of topologically complex models . Dramatic topology reduction is achieved by converting a 3D model to and from a volumetric representation . Our approach produces valid , error-bounded models and supports the creation of approximations that do not interpenetrate the original model , either being completely contained in the input solid or bounding it . Several simple to implement versions of our approach are presented and discussed . We show that these methods perform significantly better than other surface-based approaches when simplifying topologically-rich models such as scene parts and complex mechanical assemblies
