Method ClosestTimesOnTwoLines

ClosestTimesOnTwoLines(Vector3, Vector3, Vector3, Vector3, out float, out float, double)

Finds the times at which two linear trajectories are the closest to each other.

Declaration

public static bool ClosestTimesOnTwoLines(Vector3 positionA, Vector3 velocityA, Vector3 positionB, Vector3 velocityB, out float s, out float t, double parallelTest = 5E-324)

Parameters

Type	Name	Description
Vector3	positionA	Starting point of object a
Vector3	velocityA	Velocity (direction and magnitude) of object a
Vector3	positionB	Starting point of object b
Vector3	velocityB	Velocity (direction and magnitude) of object b
float	s	The time along trajectory a
float	t	The time along trajectory b
double	parallelTest	(Optional) epsilon value for parallel lines test

Returns

Type	Description
bool	False if the lines are parallel, otherwise true

Remarks

Two trajectories which may or may not intersect have a time along each path which minimizes the distance between trajectories. This function finds those two times. The same logic applies to line segments, where the one point is the starting position, and the second point is the position at t = 1.
