Abstract: We present a parallel algorithm for the construction of the hyperoctree re-pre-senting a $d$-dimensional object from a set of $n$ \mbox{$(d-1)$}-dimensional hyperoctrees, representing adjacent crossections of this object. On a $p$-processor SIMD hypercube the time complexity of our algorithm is $O(\frac m p \log p\log n)$, where $m$ is the maximum of input and output size.
