@param zDisplaceMod Displacement module that displaces the @a z
coordinate.
The GetValue() method displaces the input value by adding the output
value from this displacement module to the @a z coordinate of the
input value before returning the output value from the source
module.
This method assigns an index value of 3 to the @a z displacement
module. Passing this displacement module to this method produces
the same results as passing this displacement module to the
SetSourceMod() method while assigning it an index value of 3.
This displacement module must exist throughout the lifetime of this
noise module unless another displacement module replaces it.
Sets the @a z displacement module.
