intersection of two line segments
- Parameters
-
a [in] line segment A b [in] line segment B aT [out] parameter of intersection point on line segment A bT [out] parameter of intersection point on line segment B
- Returns
- rNone the line segments don't intersect, they have no points in common. tA and tB are not assigned.
- rOne both line segments have exactly one point in common. tA and tB contain parameters of intersection point.
- rInfinite the line segments have more than one point in common, they overlap. tA and tB are not assigned.
