Package-level declarations

Types

Anticipator

class Anticipator(spring: Spring)

Kicks a spring early enough that its peak lands on the next onset instead of just after it.

ChoiceGene

class ChoiceGene : Gene

A choice between options ways of drawing. A change fades from the old option over one visual cycle.

Ease

object Ease

Shapes for anything that travels from one value to another.

Envelope

class Envelope(attackPerSecond: Float = 14.0f, releasePerSecond: Float = 2.4f, initial: Float = 0.0f)

Rises fast and falls slowly, which is what the bars in every music player do.

Evolution

class Evolution(var morphBudget: Float = 8.0f)

Paces a drawing's changes of form by how much is happening in the music.

Gene

sealed class Gene

One part of a drawing's recipe the song can change: a count, a layout, a ground.

Genes

class Genes(seed: Long)

A drawing's recipe, and the rules that change it.

Gestures

class Gestures

Confident transients and supported structural edges, with separate continuous visual cycles.

Impulses

class Impulses(capacity: Int = 64)

The last hits, each with a place, for rings, shocks and eddies that spread from where a hit landed. The newest is index 0. Ages count heard seconds, so a pause holds every ring where it is.

MusicClock

class MusicClock(beatsPerCycle: Float = 4.0f, pullPerSecond: Float = 0.6f)

A rotation that lands on the beat when there is one, and keeps turning when there is not.

Noise1

class Noise1(seed: Int = 1)

Smooth random movement over time.

NumberGene

class NumberGene : Gene

A number in the recipe. A change glides to the new value over one visual cycle.

Slew

class Slew(maxPerSecond: Float, initial: Float = 0.0f)

Stops a value moving faster than maxPerSecond. Useful for anything a viewer tracks by eye.

Spring

class Spring(stiffness: Float = 120.0f, damping: Float = 0.55f, initial: Float = 0.0f)

A value that chases a target and overshoots a little before settling.
