NoiseNode
public NoiseNode(int seed, @NonNull ProgressDomain varyOver, float basePeriod)
Creates a NoiseNode that produces a random variation.
A new random value between 0 and 1 will be generated every basePeriod units along the varyOver domain, with the output of this node shifting smoothly between successive random values.
If varyOver is ProgressDomain.DISTANCE_IN_CENTIMETERS and the stroke input data does not indicate the relationship between stroke units and physical units (e.g. as may be the case for programmatically-generated inputs), then the output value will be null.
| Parameters | |
|---|---|
int seed |
the seed for the random number generator |
@NonNull ProgressDomain varyOver |
the source of the varying over which the random function is evaluated |
float basePeriod |
the base period of the random function |
Public methods
getBasePeriod
public final float getBasePeriod()
The base period of the random function.
getVaryOver
public final @NonNull ProgressDomain getVaryOver()
The source of the varying over which the random function is evaluated.
