Abstract

We offer computational formula of subdivision depth for tensor product 𝑛 -ary ( 𝑛 2 ) volumetric models based on error bound evaluation technique. This formula provides and error control tool in subdivision schemes over regular hexahedron lattice in higher-dimensional spaces. Moreover, the error bounds of Mustafa et al. (2006) are special cases of our bounds.
