47 : calculates an index, which of the members of the child vector is to
48 : be visualized.
49 :
50 : An example: For blinking, the Child vector should exist of two entries;
51 : for values of [0.0 .. 0.5] the first, else the last entry will be used.
52 : This mechanism is not limited to two entries, though.
