		UT_DMatrix3 &	immatrix
	)		const

overrideprotectedvirtual

Gets the impulse mass matrix of an object for an impulse at the provided point on the geometry of the object. The default implementation finds the world space position of the point and calls getImpulseMassMatrix().

Reimplemented from SIM_Solver.
