+//1, freeze all dynamic objects and avatars;
+//2, (?) disable all sky and water;
+//3, capture frames periodically, by calling "capture()";
+//4, compute pixel differences between two latest captured frames, by calling "compare()", results are stored at mDiff;
+//5, compute the number of pixels in mDiff above some tolerance threshold in GPU, by calling "calcDiffAggregate()";
+//6, use gl occlusion query to fetch the result from GPU, by calling "fetchQueryResult()";
