Check if line intersects circle
WebIf it equals 0 then the line is a tangent to the sphere intersecting it at one point, namely at u = -b/2a. If it is greater then 0 the line intersects the sphere at two points. To apply this to two dimensions, that is, the intersection of a line and a circle simply remove the z component from the above mathematics.

WebApr 19, 2024 · When you have the unit dist you use it to work out what part of the line segment to measure the circle center distance from. if u < 0 then get the length of AC if u > 1 the get length BC else get the distance from (A + AB * u) to C. If the calculated dist is less than the radius the circle is touching. Rewrite WebTo determine the position of a line with respect to a circle, all we need to do is find its distance from the center of the circle, and compare it with its radius. Then, if the distance is less than the radius, the line must …
WebJun 10, 2024 · Given the coordinates of the center point as (0,0), the radius of the circle, and the equation of a line and the task is to check whether the given line touches or intersects the circle. The line equation is in the form ax+by+c. Hence a, b, c values are given for a line equation. The three possibilities : The Line intersect the circle.
