By using inversive congruential method, this paper researches the algorithm to generate pseudo-random Numbers and the general principle for compound inversive congruential method.

In this paper, a combined number generator based on the chaotic mechanics and linear congruence generator is proposed.

Firstly, a group of lines through the model center depending on a pseudorandom number is generated. Then the intersection points of these lines and the model's surface are chosen as embedding objects.
