You\ncan create a three-dimensional histogram just fine, but you can never do\nanything with it afterwards, since its contents are inaccessible.\n\nWhat I would like to know is - are there any plans to implement this\nfunctionality anytime in the near future?   \nI've read that OpenCV 3 Full will be released on Christmas or the start\nof 2015. Will it include this functionality for the Java bindings then?\n\nI understand that this isn't a conceptual problem, since it seems to be\nworking just fine in C++ (not tried it myself, but according to the\nInternet, people are working with this).   \nOf course, I don't know how hard it is to implement this in the Java\nbindings, too.\n\nEven if this isn't fixed in the very near future, I would still like an\nofficial word about it, so I know if I just need to wait or need to try\nfinding a workaround for this (using C++, using three 1-dimensional\nhistograms, etc.).\n\nThanks in advance, and I'll gladly provide more data if needed.\n\n\nHistory\n=======\n|| by J.
