Figure 4. Spatial comparison of homogeneous Poisson point processes.
Each column displays data corresponding to a given sample pair (
). A–C: typical patterns of Sample 1 (green) and Sample 2 (purple), with an average of 
points per pattern, and an average of 
points per pattern, with 
(A), 
(B), and 
(C). D–F: mid-sections of 
-maps computed from Sample 1 and Sample 2, using 
. G–I: isosurfaces computed from 
-maps for thresholds equal to 
(purple) and 
(green) (
). Yellow dotted square in D–I: outline of the unit cube containing generated points.
