MT random main class. In Unity3d there is already a Random number generator based on the platform-specific random generator. Here we present an alternative Random library for Unity3d designed to generate uniform Pseudo-Random deviates. The library use a fast PRNG (Mersenne-Twister) to generate: Floating Number in range [0-1] and in range [n-m], Vector2 and Vector3 data types. Which kind of transformations I can apply to the random uniform deviates? The uniform deviates can be transformed with the distributions: Standard Normal Distribution and Power-Law. In addition is possible to generate floating random deviates coming from other distributions: Poisson, Exponential and Gamma.
