Library "Interpolation" Functions for interpolating values. Can be useful in signal processing or applied as a sigmoid function.
linear(k, delta, offset, unbound) Returns the linear adjusted value. Parameters: k: A number (float) from 0 to 1 representing where the on the line the value is. delta: The amount the value should change as k reaches 1. offset: The start value. unbound: When true, k values less than 0 or greater than 1 are still calculated. When false (default), k values less than 0 will return the offset value and values greater than 1 will return (offset + delta).
quadIn(k, delta, offset, unbound) Returns the quadratic (easing-in) adjusted value. Parameters: k: A number (float) from 0 to 1 representing where the on the curve the value is. delta: The amount the value should change as k reaches 1. offset: The start value. unbound: When true, k values less than 0 or greater than 1 are still calculated. When false (default), k values less than 0 will return the offset value and values greater than 1 will return (offset + delta).
quadOut(k, delta, offset, unbound) Returns the quadratic (easing-out) adjusted value. Parameters: k: A number (float) from 0 to 1 representing where the on the curve the value is. delta: The amount the value should change as k reaches 1. offset: The start value. unbound: When true, k values less than 0 or greater than 1 are still calculated. When false (default), k values less than 0 will return the offset value and values greater than 1 will return (offset + delta).
quadInOut(k, delta, offset, unbound) Returns the quadratic (easing-in-out) adjusted value. Parameters: k: A number (float) from 0 to 1 representing where the on the curve the value is. delta: The amount the value should change as k reaches 1. offset: The start value. unbound: When true, k values less than 0 or greater than 1 are still calculated. When false (default), k values less than 0 will return the offset value and values greater than 1 will return (offset + delta).
cubicIn(k, delta, offset, unbound) Returns the cubic (easing-in) adjusted value. Parameters: k: A number (float) from 0 to 1 representing where the on the curve the value is. delta: The amount the value should change as k reaches 1. offset: The start value. unbound: When true, k values less than 0 or greater than 1 are still calculated. When false (default), k values less than 0 will return the offset value and values greater than 1 will return (offset + delta).
cubicOut(k, delta, offset, unbound) Returns the cubic (easing-out) adjusted value. Parameters: k: A number (float) from 0 to 1 representing where the on the curve the value is. delta: The amount the value should change as k reaches 1. offset: The start value. unbound: When true, k values less than 0 or greater than 1 are still calculated. When false (default), k values less than 0 will return the offset value and values greater than 1 will return (offset + delta).
cubicInOut(k, delta, offset, unbound) Returns the cubic (easing-in-out) adjusted value. Parameters: k: A number (float) from 0 to 1 representing where the on the curve the value is. delta: The amount the value should change as k reaches 1. offset: The start value. unbound: When true, k values less than 0 or greater than 1 are still calculated. When false (default), k values less than 0 will return the offset value and values greater than 1 will return (offset + delta).
expoIn(k, delta, offset, unbound) Returns the exponential (easing-in) adjusted value. Parameters: k: A number (float) from 0 to 1 representing where the on the curve the value is. delta: The amount the value should change as k reaches 1. offset: The start value. unbound: When true, k values less than 0 or greater than 1 are still calculated. When false (default), k values less than 0 will return the offset value and values greater than 1 will return (offset + delta).
expoOut(k, delta, offset, unbound) Returns the exponential (easing-out) adjusted value. Parameters: k: A number (float) from 0 to 1 representing where the on the curve the value is. delta: The amount the value should change as k reaches 1. offset: The start value. unbound: When true, k values less than 0 or greater than 1 are still calculated. When false (default), k values less than 0 will return the offset value and values greater than 1 will return (offset + delta).
expoInOut(k, delta, offset, unbound) Returns the exponential (easing-in-out) adjusted value. Parameters: k: A number (float) from 0 to 1 representing where the on the curve the value is. delta: The amount the value should change as k reaches 1. offset: The start value. unbound: When true, k values less than 0 or greater than 1 are still calculated. When false (default), k values less than 0 will return the offset value and values greater than 1 will return (offset + delta).
using(fn, k, delta, offset, unbound) Returns the adjusted value by function name. Parameters: fn: The name of the function. Allowed values: linear, quadIn, quadOut, quadInOut, cubicIn, cubicOut, cubicInOut, expoIn, expoOut, expoInOut. k: A number (float) from 0 to 1 representing where the on the curve the value is. delta: The amount the value should change as k reaches 1. offset: The start value. unbound: When true, k values less than 0 or greater than 1 are still calculated. When false (default), k values less than 0 will return the offset value and values greater than 1 will return (offset + delta).
