Function VectorMath.LineCircleIntersectionFactors

LineCircleIntersectionFactors (float2 point, float2 direction, float radius, out float t1, out float t2)

Calculates the two intersection points (point + direction*t) on the line where it intersects with a circle at the origin.

Public Static

Calculates the two intersection points (point + direction*t) on the line where it intersects with a circle at the origin.

t1 will always be less than or equal to t2 if there are intersections.

Returns false if there are no intersections.

float2	point	A point on the line
float2	direction	The normalized direction of the line
float	radius	The radius of the circle at the origin.
out float	t1	The first intersection (if any).
out float	t2	The second intersection (if any).
