clamp(lowerBound:upperBound:)
Replaces values in the noise field outside the specified range with the values at the endpoints of that range.
Declaration
func clamp(lowerBound: Double, upperBound: Double)Parameters
- lowerBound:
The minimum value to keep in processed noise.
- upperBound:
The maximum value to keep in processed noise.
Discussion
For example, if you specify lower and upper bounds of -0.5 and 0.5, this operation replaces values less than -0.5 with -0.5 and values greater than 0.5 with 0.5.
