All physics-based nodes freeze if the distance between them and the camera is bigger than the Physics distance. The distance is measured from the camera to the node's bound. Physics Distance = 40 unitsPhysics Distance = 40 units Physics Distance = infPhysics Distance = inf Physics Distance = 40 unitsPhysics Distance = inf距相机的距离，从该距离将不会计算出物理相互作用。 如果所有基于物理的节点与相机之间的距离大于“物理”距离，则冻结。 距离是从摄像机到节点边界的距离。 Physics Distance = 40 units物理距离= 40个单位 Physics Distance = inf物理距离= inf
Budget	Physics simulation time budget in seconds.物理模拟时间预算，以秒为单位。
FPS	Fixed frame rate used to simulate physics. Physics frame rate is independent of the rendering one. 注意 If physics takes more than the assigned time budget, further calculations are delayed. These calculations shall be performed during the subsequent rendering frames, making physics simulation look like in a "slo-mo" mode. The default budget is 50 ms, but it can be increased, as necessary.If physics takes more than the assigned time budget, further calculations are delayed.
