IntersectPoint:

Description

Find where point opposite segment intersects segment. It gives a proportion of AB that the orthogonal line passing through C meets. If outside (0,1) it does not pass through AB

Usage

IntersectPoint(A, B, C)

Arguments

A
(x,y) point on one end of line segment
B
(x,y) point on other end of line segment
C
(x,y) point to compare to line segment

Value

returns a value which is the proportion of the length of AB where AC proects onto the line defined by AB. If the return value is between 0 and 1, the point is opposite the line segment. If negative, it falls on the A side of AB; if greater than 1, it falls to the B side of AB.
