| Description |
A displacement providing a rough, cast metal-like finish.
The appearance of the roughness can be controlled precisely.
The magnitude of the surface perturbations, expressed as
a factor, typically in the range 0.0 to 1.0, is specified
by argument "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 give fine detail
of the roughness.
Argument "sharpness" is an integer value which
controls the sharpness of the perturbations.
A value of 1 will give abrupt, sharp changes
between the peaks and troughs of the displacements, while
a larger value such as 3 or 4 will give smoother transitions.
An overall scaling factor may be supplied in argument
"scale"; increasing this value will make the
surface perturbations appear larger.
This displacement is suitable for any surface where an
uneven appearance is required.
