函数: computeLineSegmentLineSegmentIntersection()

computeLineSegmentLineSegmentIntersection(x00: number, y00: number, x01: number, y01: number, x10: number, y10: number, x11: number, y11: number, result?: Cartesian2): Cartesian2

Compute the intersection between 2 line segments

参数

x00

number

The x coordinate of the first line's first vertex.

y00

number

The y coordinate of the first line's first vertex.

x01

number

The x coordinate of the first line's second vertex.

y01

number

The y coordinate of the first line's second vertex.

x10

number

The x coordinate of the second line's first vertex.

y10

number

The y coordinate of the second line's first vertex.

x11

number

The x coordinate of the second line's second vertex.

y11

number

The y coordinate of the second line's second vertex.

result?

Cartesian2

The instance into to which to copy the result. If this parameter is undefined, a new instance is created and returned.

返回

Cartesian2

The intersection point, undefined if there is no intersection point or lines are coincident.

示例

const result = Cesium.Intersections2D.computeLineSegmentLineSegmentIntersection(0.0, 0.0, 0.0, 2.0, -1, 1, 1, 1);
// result === new Cesium.Cartesian2(0.0, 1.0);
