public abstract class FloatFunction
extends DeepObject
implements Exportable

Provides a float value based on a parameter ranging from 0 to 1.

Nested Class Summary

static class	FloatFunction.Constant Returns a constant value.
static class	FloatFunction.InAndOut A float function that blends linearly from a start value to an end value, then back to the start value.
static class	FloatFunction.Linear Linearly interpolates between a start and an end value.
static class	FloatFunction.Multipoint A float function that blends between an arbitrary number of values.
static class	FloatFunction.ThreePoint A float function that blends linearly from a start value to a middle value, then to an end value.
