The dnoise function returns a vector with three random components between -1 and 1 for the given vector argument. When the argument is a vector constant, also the output of the noise function will be a vector constant. When you use an increasing argument such as
dnoise( vec( time, time, time ) )
you will get a noisy curve for each component of the returned vector which will have slightly changes from value to value rasulting in a smoother noise curve as the random functions returns.
The dnoise function is in all aspects similar to the noise function.
