Abstract:The use of 3D shapes in different domains such as in engineering; entertainment; cultural heritage or medicine; is essential for representing 3D physical reality. Regardless of whether the 3D shapes are representing physically or digitally born objects; meshes are a versatile and common representation for the 3D reality. Nonetheless; the mesh generation process does not always produce qualitative results; thus incomplete; non-orientable or non-manifold meshes frequently are the input for the domain application. The domain application itself also demands special requirements; e.g. an engineering simulation requires a volumetric mesh either tetrahedral or hexahedral; while a cultural heritage color enhancement uses a triangular or quadrangular mesh; or in both cases even hybrid meshes. Moreover; the processes applied on the meshes (e.g. modeling; simulation; visualization) need to support some operations; such as querying neighboring information or enabling dynamic changes of geometry and topology. These operations need to be robust; hence the neighboring information can be consistently updated; during the dynamic changes. Dealing with this mesh diversity usually requires dedicated data structures for performing in the given domain application. This paper compiles the considerations toward designing a data structure for dynamic meshes in a generic and robust manner; despite the type and the quality of the input mesh. These aspects enable a flexible representation of 3D shapes toward general purpose geometry processing for dynamic meshes in 2D and 3D.
