9 A new method for the statistical analysis of 3-D point processes, based on the family of Minkowski-
0 Functionals , is explained and applied to modelled galaxy distributions generated by a toy-model
5 and cosmological simulations of the large-scale structure in the Universe. These measures are

/ sensitive to both, geometrical and topological properties of spatial patterns and appear to be
h very effective in discriminating different point processes. Moreover by the means of conditional
p
- subsampling, different building blocks of large-scale structures like sheets, filaments and clusters
o can be detected and extracted from a given distribution.
