But you should be able to write one yourself if you dig a little bit into vector mathematics.
I think this page (http://www.netcomuk.co.uk/~jenolive/vect14.html) illustrates what you are looking for in the section "The angle between a line and a plane". So you would need to define the "normal vector" of your plane (this page might be helpful: http://math.stackexchange.com/questions/137538/calculate-the-vector-normal-to-the-plane-by-given-points) and determine the angles. Jmol math includes vector operations (see http://jena3d.fli-leibniz.de/doc/jmol_scripting/index.htm?ver=14.0#jmolmath). So it shouldn't be to hard to do this. Maybe quaternions (implemented in Jmol) can be helpful here but I don't know enough about them to be sure.
