A Lie group integrator is a numerical integration method for differential equations built from coordinate-independent operations such as Lie group actions on a manifold.[1][2][3] They have been used for the animation and control of vehicles in computer graphics and control systems/artificial intelligence research.[4] These tasks are particularly difficult because they feature nonholonomic constraints.
