/**
 * applies a noise
 *
 * @remark
 *
 * This node is very powerful and can be used to affect many parts of a shader, or even generate forces in a particle system.
 * It can also create fbm effects, where several layers of noise are added to each other, giving a fractal effect.
 *
 * Another very interesting use case is to use multiple noise nodes, where a first one is used to modify the input position of a second one.
 * This is called domain warping and can help you create very complex effect quickly.
