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

Claudio MiroloUniversity of Udine, Italy

Stefano CarpinUniversity of California-Merced, USA

Enrico PagelloUniversity of Padova, Italy

Iterations for decreasing coherence (left to right) and for stronger (squares) / weaker initialization
