removeRigidBody 中mesh=null

world.js 中 intersectTest  是多余的么？

            var lp2y=p.localPoint2.y;

            var lp2z=p.localPoint2.z;  不需要增加var变量

constraint.restitution

constraint.friction  可以优化，只计算一次，放在if(num==0)判断后

var gVel = new Vec3().addScaledVector( this.gravity, this.timeStep );  不需要每次计算
