gosper_encode

function gosper_encode(
   point,
   level,
   size,
   orientation?): number;

Defined in: gosper.ts:171

Maps a point to its position along the Gosper curve.

The island is centred on the origin, so translate your data there first. Points outside it return -1 rather than aliasing onto an interior cell.

Parameters

Parameter	Type	Default value	Description
point	Point	undefined	The point to index.
level	number	undefined	Curve level; the curve has 7^level cells.
size	number	undefined	Level-0 hexagon size, from gosper_size.
orientation	HexOrientation	"flat"	Which way up the hexagons sit. Defaults to "flat".

Returns

number

The curve index in [0, 7^level), or -1 if outside the island.
