OrbFrame class

One rendered instant: a reusable, growable buffer of dots. Each dot is stride doubles — x, y, z, radius, ink (0 = full ink, 1 = none), alpha. order holds the indices sorted far → near after sortByDepth.

Constructors

OrbFrame({int capacity = 512})

Properties

Methods

add(double x, double y, double z, double radius, double ink, [double alpha = 1]) → void

addLine(double x1, double y1, double x2, double y2, double ink, double alpha, double width) → void

addTinted(double x, double y, double z, double radius, double ink, double alpha, double red, double green, double blue, double tint) → void

Like add, with a colour of its own: red, green and blue in 0..1, and tint — how far the dot leans from the ink toward that colour (0 = pure ink, 1 = pure tint). blend carries the tint across a morph.

alpha(int i) → double

clampRadius(double rMin) → void

clear() → void

copyFrom(OrbFrame other) → void

ink(int i) → double

multiplyAlpha(double factor) → void

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

radius(int i) → double

scaleAbout(double cx, double cy, double scale) → void

sortByDepth() → void

tint(int i) → double

How far dot i leans from the ink toward its own colour, 0..1.

toString() → String

A string representation of this object.

inherited

translate(double dx, double dy) → void

x(int i) → double

y(int i) → double

z(int i) → double

Operators

operator ==(Object other) → bool

The equality operator.

Static Methods

blend(OrbFrame from, OrbFrame to, double progress, OrbFrame out, {double stagger = 0.35}) → void

Writes the index-mapped morph of from into to at progress into out. Dots leave in a staggered wave (stagger of the progress span) so the change reads as a flow rather than a slide. Lines cross-fade.

Constants

lineStride → const int
