Exploring Different Coherence Dimensions toAnswer Proximity Queries for Convex Polyhedra

• From exploiting coherence to adapting to variable coherence• Multidimensional analysis of the concept of coherence• Experiments

in Guibas’ et al. style• First-order coherence:

strong improvement• Second-order coherence:

up to 15-20% furtherimprovement
