Examples of net.sourceforge.jiu.color.data.OnDemandHistogram3D

net.sourceforge.jiu.color.data.OnDemandHistogram3D
A data class for a three-dimensional histogram, creating counters on demand only, not allocating counters for all possible entries at the beginning. The creation on demand happens to save space.
Note: Rewrote from scratch for version 0.15.0 to use hash tables instead of int arrays. New version creates and throws away a lot of objects, which had been a problem with early JVMs but should be OK these days. @author Marco Schmidt
