Experimental

A point source over plain arrays, with a settable transform.

Properties

Property	Modifier	Type	Description	Inherited from
count	readonly	number	Experimental Number of points.	PointSource2D.count
offsetX	readonly	number	Experimental	PointSource2D.offsetX
offsetY	readonly	number	Experimental	PointSource2D.offsetY
scaleX	readonly	number	Experimental	PointSource2D.scaleX
scaleY	readonly	number	Experimental	PointSource2D.scaleY
version	readonly	number	Experimental Bumped whenever positions or count change; the index rebuilds on the next query.	PointSource2D.version
