Just lately I've created a simple class for searching itersected triangle.
(as no one responed to my question about the some problem few day earlier)
Its quite fast.
Maybe someone can make it more generally usable.
Current version takes just TringleArray (from the picked shape3d), EyePoint
and RayDirection
Return the point and the distance.
Hope this help:
