NettetIn geometry, an intersection is a point, line, or curve common to two or more objects (such as lines, curves, planes, and surfaces). The simplest case in Euclidean geometry is the line–line intersection between two distinct lines, which either is one point or does not exist (if the lines are parallel ). Nettet25. mai 2016 · // this is an adaption from a hackerrank problem about 'lasers' and 'walls', so for future reference the line segment anchored at the origin will be // referred to as a 'laser', the other line segment a 'wall'. // following standard line notation, y = M*x+B, all slopes will be referred to as M, and y-intercepts as B.

We can parametrize the first line segment on the parameter interval t ∈ [ 0, 1] and the second on the parameter interval s ∈ [ 0, 1], then use Solve to find the intersection, restricting to those two intervals. If there is no intersection, Solve returns an empty list, so the Length of the result is zero.

NettetWhen the two segments intersect, the points (X1 (t1), Y1 (t1)) and (X2 (t2), Y2 (t2)) are the same. Setting the equations for the points equal gives: x11 + dx1 * t1 = x21 + dx2 * t2 y11 + dy1 * t1 = y21 + dy2 * t2 You can rearrange those equations to get: x11 - x21 + dx1 * t1 = dx2 * t2 y11 - y21 + dy1 * t1 = dy2 * t2 And then: Nettet12. jun. 2024 · $\begingroup$ @mathmaniage The cross product has a sign which depends on the relative orientation of two lines which meet at a point.
