+**Beta Law Distribution** - is given by the following formula (see image below) where **t** is the position of the point in the segment [0, 1].

+
+The beta parameter is usually set between 1.01 (narrow mesh) and 1.00001 (very narrow mesh).
+Values between [-1, 1] are forbidden to ensure validity of the log.
+Negative values are allowed and result with positions distributed in the opposite direction.
