MetaballWaveShape class

A gooey crest made of blobCount evenly-spaced blobs that drift with the motion phase. Each blob is a Gaussian bump of the given radius; blobs are combined with a smooth union so nearby blobs merge into one bulge peaking at amplitude, while distant blobs stay separate.

Properties

amplitude → double

final

baseline → double

The normalized vertical anchor of the crest line, [0, 1].

final

blobCount → int

final

hashCode → int

The hash code for this object.

no setter, override

radius → double

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

sampleAt(double x, double phase) → double

Sample the surface height (in amplitude units) at normalized x in [0, 1] with the given phase in radians. This is the crest offset only; vertical placement is carried separately by baseline.

override

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
