I am trying to calculate the dihedral angle between four points.
I considered two planes (ABC & BCD) and calculate the dot products of two
normals (n1 and n2)to these plane.
I compared theeta values of dihedral angle with ampac and some values are
negative. I am geting all positive value.
Any one knows how to calculate sign of dihedral angle.
