A procedure is described for the simulation of clusters and aggregates
which are constrained to have a definite fractal dimension. The fract
al (Hausdorff-Besicovitch) dimension of the simulated clusters was det
ermined for two dimensional projections of clusters using methods base
d on the radius of gyration and (1)Voss. The two approaches are compar
ed and used to develop a correlation between the fractal dimension of
the cluster and its two dimensional projection.
