This paper presents a new mesh conversion template, called HEXHOOP, that fully automates
a conversion from a hex-dominant mesh to an all-hex mesh. A HEXHOOP template subdivides
a hex/prism/pyramid element to a set of smaller hex elements while maintaining the
topological conformity with neighboring elements. A HEXHOOP template is constructed
by assembling sub- templates, cores and caps. A dicing template for a hex. and a
prism is constructed by choosing the appropriate combination of a core and caps. A
template that dices a pyramid without losing conformity to the adjacent element is
derived from a HEXHOOP template. Some experimental results show that the HEXHOOP
templates successfully convert a hex-dominant mesh to an all-hex mesh.
