# Hair Intersection

This Node is similar to the Hair Collision Node, except that velocity vectors, not geometry, will be checked for collision with guides or hair. All moving objects, including Thinking Particles particles, can be checked with regard to intersection, using a spherical **area of detection** defined in this Node.
