SYS_Math.intersects() method

Determine whether two polygons intersect

Signature

function intersects(polygon1: TSYS_MathPolygonInput, polygon2: TSYS_MathPolygonInput): boolean;

Parameters

Parameter	Type	Description
polygon1	TSYS_MathPolygonInput	Polygon 1
polygon2	TSYS_MathPolygonInput	Polygon 2

Returns

boolean

Whether they intersect

Remarks

Determine whether the regions of two polygons have any overlap (including containment, partial intersection, and boundary contact)

Example

// 1. 部分重叠的两个矩形 → true
const trace = [{ x: 0, y: 0 }, { x: 100, y: 0 }, { x: 100, y: 80 }, { x: 0, y: 80 }];
const keepout = [{ x: 50, y: 20 }, { x: 150, y: 20 }, { x: 150, y: 60 }, { x: 50, y: 60 }];
console.log('走线闯入禁布区：', eda.sys_Math.intersects(trace, keepout));

// 2. 完全分离 → false
const far = [{ x: 200, y: 0 }, { x: 280, y: 0 }, { x: 280, y: 40 }, { x: 200, y: 40 }];
console.log('走线远离另一区域：', eda.sys_Math.intersects(trace, far));

// 3. 完全包含也是相交的一种 → true
const small = [{ x: 20, y: 20 }, { x: 60, y: 20 }, { x: 60, y: 50 }, { x: 20, y: 50 }];
console.log('小区域整体在走线范围内：', eda.sys_Math.intersects(trace, small));

// 4. 仅边界贴合同样算相交 → true
const touching = [{ x: 100, y: 0 }, { x: 180, y: 0 }, { x: 180, y: 40 }, { x: 100, y: 40 }];
console.log('两区域边界贴合：', eda.sys_Math.intersects(trace, touching));
