nxConstraints

nxConstraints are dynamic connections and forces affecting the way in which particles interact. There are several constraint types, which can be layered for multiple effects, all within one nxConstraints object. You can create stretchy springs between particles, add forces of attraction and repulsions and even simulate fluid properties like viscosity and surface tension.
nxConstraints 是影响粒子相互作用方式的动态连接和力。nxConstraints 对象提供多种约束类型，可以分层叠加以实现多种效果。您可以在粒子之间创建弹性弹簧，添加吸引力和排斥力，甚至可以模拟流体特性，例如粘度和表面张力。
