Detailed Description

This is a VirtualSite that computes the particle location based on three other particles' locations.

If r₁ is the location of particle 1, r₁₂ is the vector from particle 1 to particle 2, and r₁₃ is the vector from particle 1 to particle 3, then the virtual site location is given by

r₁ + w₁₂r₁₂ + w₁₃r₁₃ + w_cross(r₁₂ x r₁₃)

The three weight factors are user-specified. This allows the virtual site location to be out of the plane of the three particles.

Constructor & Destructor Documentation

def __init__	(		self,
			args
	)

init(OpenMM::OutOfPlaneSite self, int particle1, int particle2, int particle3, double weight12, double weight13, double weightCross) -> OutOfPlaneSite init(OpenMM::OutOfPlaneSite self, OutOfPlaneSite other) -> OutOfPlaneSite

Create a new OutOfPlaneSite virtual site.

Parameters

particle1	the index of the first particle
particle2	the index of the second particle
particle3	the index of the third particle
weight12	the weight factor for the vector from particle1 to particle2
weight13	the weight factor for the vector from particle1 to particle3
weightCross	the weight factor for the cross product
