Short version:

You need to determine if the point is on the plane the traingle
describes.  After that, you compute the barycentric coordinates of the
point. To help, you find out which component of the plane's normal
vector is predominant and discard it, thus, projecting it in 2D on two
remaining coordinate planes.
