Function intersect
Calculates the point of intersection of two lines in two or three dimensions and of a line and a plane in three dimensions. The inputs are in the form of arrays or 1 dimensional matrices. The line intersection functions return null if the lines do not meet.
Note: Fill the plane coefficients as x + y + z = c and not as x + y + z + c = 0.
Syntax
math.intersect(endPoint1Line1, endPoint2Line1, endPoint1Line2, endPoint2Line2)
math.intersect(endPoint1, endPoint2, planeCoefficients)
