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 + wcross(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.
