Camera2D

class Camera2D(wander: Float = 0.1f, punch: Float = 0.1f, roll: Float = 0.1f, shake: Float = 0.004f, cuts: Boolean = true, minZoom: Float = 0.94f, maxZoom: Float = 1.3f, seed: Int = 1)

Moves a whole flat drawing, the way CameraRig moves a flight.

A wander, a zoom punch on the kick (early, when the queue shows it coming), a nudge on the snare, a roll, a whip on a drop, and now and then a cut to a new framing at a supported section boundary. Pans are shares of the screen, angle is radians.

Constructors

Camera2D

constructor(wander: Float = 0.1f, punch: Float = 0.1f, roll: Float = 0.1f, shake: Float = 0.004f, cuts: Boolean = true, minZoom: Float = 0.94f, maxZoom: Float = 1.3f, seed: Int = 1)

Properties

angle

var angle: Float

orbit

var orbit: Float

Radius of a slow orbit, as a share of the screen. Zero leaves it off.

orbitRate

var orbitRate: Float

Laps per four-pulse visual cycle when rhythm is usable.

panX

var panX: Float

panY

var panY: Float

zoom

var zoom: Float

Functions

advance

fun advance(state: VizRenderState)

Moves the camera on by one frame. The same state twice moves it once. A new frame at an instant already drawn still applies its hits, without adding elapsed time.

project

fun project(x: Float, y: Float, aspect: Float, parallax: Float, into: Anchor)

Where a point at x, y (shares of the screen, before the camera) lands on screen, as shares. aspect is width over height. Answers into into.

reset

fun reset()

shove

fun shove(amount: Float)

Pushes the zoom the way a kick does, for a drawing's own hits.
