-Randomness is used in different parts of the path tracer. One example is picking $\xi$ as part of the Russian roulette technique. Such a number is obtained by employing a random number generator (\gls{RNG}). In rasterization, the necessity for \gls{RNG} is less common but may still be required for specific effects. A variety of \glspl{RNG} are available that differ in essential characteristics. Some of the characteristics to consider when choosing a suitable \gls{RNG} are:

   \item{Statistical Quality} — The \gls{RNG} should generate numbers that are statistically random. This means that the numbers should be uniformly distributed and have a low correlation between them.
