Hello,  I am interested in using the function isInTriangleVec3() from the VectorUtil library but I can't find any documentation on how to use it.  The closest I found was vertexInTriangle() but it is missing parameters ac, ab and ap.  What I have is this:

    public static boolean isInTriangleVec3(final float[] a, final float[] b, final float[] c,
                                                           final float[] p,final float[] ac, final float[] ab,
                                                           final float[] ap)

I assume a, b and c are the 3 vertices of the current triangle. 'p' is the vertex that I am testing.  What are ac, ab and ap?
