The first line segment, represented as an array of two points [T_Point, T_Point].
The second line segment, represented as an array of two points [T_Point, T_Point].
An object containing:
pt: The intersection point as [x, y]. This value will be the calculated intersection point,
even if it is outside the bounds of the segments.doesIntersect: A boolean indicating whether the intersection lies within both line segments.// Define two line segments
const line1: T_Line = [[0, 0], [10, 10]];
const line2: T_Line = [[0, 10], [10, 0]];
// Check for intersection
const result = lineLineIntersection(line1, line2);
console.log(result);
// Output: { pt: [5, 5], doesIntersect: true }
// Define two non-intersecting line segments
const line3: T_Line = [[0, 0], [5, 5]];
const line4: T_Line = [[6, 6], [10, 10]];
const result2 = lineLineIntersection(line3, line4);
console.log(result2);
// Output: { pt: [5.5, 5.5], doesIntersect: false }
Calculates the intersection point of two line segments, if it exists.
This function determines whether two line segments intersect and returns the intersection point (if any) along with a boolean indicating whether an intersection exists within the bounds of the segments.
