LineCircleIntersect

Description

Finds the intersection points of a line and a circle.

FUNCTION LineCircleIntersect(
				begPt   : VECTOR;
				endPt   : VECTOR;
				cenPt   : VECTOR;
				radius  : REAL;
				VAR pt1 : VECTOR;
				VAR pt2 : VECTOR): BOOLEAN;
def vs.LineCircleIntersect(begPt, endPt, cenPt, radius):
    return (BOOLEAN, pt1, pt2)

Parameters

Name Type Description
begPt VECTOR
endPt VECTOR
cenPt VECTOR
radius REAL
pt1 VECTOR
pt2 VECTOR

Remarks

In VS Python, this function returns 3-element tuples with gibberish in the third element regardless whether you give it 2- or 3-element tuples. This function checks and returns the intersection of the circle with an infinite line defined by the two supplied points.
