We propose a compact data structure for volumetric meshes of arbitrary topology and bounded valence that offers cell–face, face–edge, and edge–vertex incidence queries in constant time. Our structure is simple to implement, easy to use, and allows for arbitrary, user-defined 3-cells such as prisms and hexahedra, while remaining very efficient in memory usage compared to previous work. Its time complexity for commonly-used incidence and adjacency queries such as vertex and dart one-rings is analyzed.
