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

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.
