Function: edgeAngles()

function edgeAngles(polygon: Polygon, normalizeTo: number): Generator<number>;

Defined in: edge-angles.ts:30

Generate normalized edge angles from polygon edges.

Parameters

Parameter	Type	Description
polygon	Polygon	The polygon to extract edge angles from
normalizeTo	number	Angle to normalize to (e.g., Math.PI * 2 for full rotation, Math.PI / 2 for quadrant)

Returns

Generator<number>

Generator that yields edge angles, normalized to the specified range

Example

const polygon: Polygon = [
  { x: 0, y: 0 },
  { x: 1, y: 1 },
  { x: 0, y: 2 },
  { x: -1, y: 1 }
];
const angles = edgeAngles(polygon);
for (const angle of angles) {
  console.log(angle);
}
// Output:
// 0.7853981633974483
// 2.356194490192345
// 3.9269908169872414
