| Description |
A displacement providing an irregular casting pattern.
This pattern is derived from two superimposed noise functions,
providing displacements and indentations, with
the indentations being used to scale the displacements.
The magnitude of the surface displacements, expressed as
a factor, typically in the range 0.0 to 1.0, is specified
by argument "casting amplitude", and the amplitude of
the indentations that superimpose the displacements is
specified by "dented amplitude".
An integer value which controls the detail or complexity
of the texture is specified by argument "detail",
such that a value of 1 will give a simple perturbation,
while a larger value such as 5 or 6 will produce fine detail
in the pattern.
An overall scaling factor may be supplied in argument
"scale"; increasing this value will make the
surface perturbations appear larger.
Scaling of the indentations can be controlled separately
by the argument "dented scale".
The relative contributions made by the displacements and
indentations are controlled by argument
"dented threshold".
This value should vary between 0.0 and 1.0, with a value
of 0.0 causing maximum interaction.
This displacement is suitable for any surface where an
irregular roughness is required.
