Well... you just have to calculate the distance from a certain point to the plane (using vector math). Then you check wheter that vertex is in front of/on the back side of/on the plane and do the things you would like to do considering this.

If you don''t know what I mean... just mail me at mitolah@hotmail.com. BUT!! Don''t bother to mail me if you don''t know how vector math goes (I will not be you MATH teacher)
