type Overlap

type Overlap interface {
	density.Interpolator

	// BufferSize calculates buffer size required to represent the
	// underlying grid.
	BufferSize() int

	// ScaleVecs converts a vector array into the overlap's code units.
	ScaleVecs(vs []geom.Vec, vcb *geom.CellBounds)

	// Add adds the contents of buf to grid where buf is the overlap grid and
	// grid is the domain grid. The domain grid is contained within the given
	// cell bounds.
	Add(buf, grid density.Buffer)
}
