Nettet20. jul. 2015 · To find the intersection point of the x-axis we do: m1*x+b1 = m2*x+b2 m1*x-m2*x = b2 - b2 x (m1-m2) = (b2-b1) x = (b2-b1) / (m1-m2) To find y, you use of the function expressions and replace x for its value (b2-b1) / (m1-m2). So: y = m1 * [ (b2-b1) / (m1-m2)] + b1 You have (this.b - line.b), change to (line.b - this.b). NettetThe first input line has an integer n: the number of line segments.

But when intersection does not occur often, a better way probably is to reverse these steps: express the straight lines in the form of y = ax + b (line passing A,B) and y = cx + d (line passing C,D)

Nettet12. mar. 2024 · 1) If you just want to know whether the line intersects the triangle (without needing the actual intersection point): Let p1,p2,p3 denote your triangle. Pick two points q1,q2 on the line very far away in both directions. Let SignedVolume (a,b,c,d) denote the signed volume of the tetrahedron a,b,c,d. NettetInstead of a vertical line sweeping the plane from left to right, radial sweep involves a ray that rotates around a central point (like a radar screen): In this case, we sort points/events by their bearing instead of by their x- and y-coordinates. Besides that, the mechanics are the same as those of normal line sweep. 2003 - Seeing the Boundary.
