// NOTE:PERFORMANCE
// BEPUphysics uses an iterative system to solve constraints. You can tell it to do more or less iterations.
// Less iterations is faster; more iterations makes the result more accurate.
//
// The amount of iterations needed for a simulation varies. The "Wall" and "Pyramid" simulations are each fairly
// solver intensive, but as few as 4 iterations can be used with acceptable results.
// The "Jenga" simulation usually needs a few more iterations for stability; 7-9 is a good minimum.
//
// The Dogbot demo shows how accuracy can smoothly increase with more iterations.
// With very few iterations (1-3), it has slightly jaggier movement, as if the parts used to construct it were a little cheap.
// As you give it a few more iterations, the motors and constraints get more and more robust.
//
// Many simulations can work perfectly fine with very few iterations,
// and using a low number of iterations can substantially improve performance.
//
// To change the number of iterations used, uncomment and change the following line (10 iterations is the default):
Scene.Solver.IterationLimit = 10;
