abstract = {In this contribution, we present an optimal halftoning algorithm
that uniformly distributes pixels over a hexagonal grid. This
method is based on a slightly modified error-diffusion approach
presented at SIGGRAPH 2001. Our algorithm's parameters are
optimized using a simplex downhill search method together with a
blue noise based cost function . We thus present a mathematical
basis needed to perform spectral and spatial calculations on a
hexagonal grid. The proposed algorithm can be used in a wide
variety of printing and visualization tasks. We introduce an
application where our error-diffusion technique can be directly
used to produce clustered screen cells.},
