ForceFields::MMFF::OopBendContrib::OopBendContrib ( ForceField * owner )

Constructor.

void ForceFields::MMFF::OopBendContrib::addTerm	(	unsigned int	idx1,
		unsigned int	idx2,
		unsigned int	idx3,
		unsigned int	idx4,
		const MMFFOop *	mmffOopParams )

Adds an out-of-plane term to the force field contrib.

The Wilson angle is between the vector formed by atom2-atom4 and the angle formed by atom1-atom2-atom3

Parameters

idx1	index of atom1 in the ForceField's positions
idx2	index of atom2 in the ForceField's positions
idx3	index of atom3 in the ForceField's positions
idx4	index of atom4 in the ForceField's positions
