Hi! I'm looking to do some pretty specific stuff with splines, and part of that is getting the closest point to a spline very rapidly. I have a few other options than this, but the main function that I'm looking at using is CurveUtility.GetNearestPoint(). Unfortunately, I can't find any documentation on this function, and instead of using a float3 or Vector3 for the point, it uses a Ray. Maybe I'm feeble of imagination, but I can't understand why a Ray is used, and which way - is the direction of the ray used, or just the location? In any case, I would love to see any documentation of this function, or an explanation of its behavior, and that failing, I would appreciate any guesses as to why it uses a Ray and how that information is processed.
