雷诺兹的类鸟物体的经典工作模拟了定向粒子组、类鸟物体或简单的物体的极化运动。为此，引入了三个转向向量。凝聚力是指群体停留在群体中心的倾向，对齐可以将它们的速度平滑到相似的值，而分离可以帮助它们避免相互碰撞。如果没有引入动力，群体会有些随机地漂移，因此适当的外部引导力对于正确的群体行为是必要的。正如在秋季鸟类聚集期间观察到的那样，鸟类有时会以上述框架未捕获的方式移动。一些鸟，通常是鸟群边缘的鸟，突然飞出。然后羊群就会追赶这位领导者。在雷诺兹的原作中，凝聚力和分离力是两个互补的方向。我们为这种联盟引入了一种补充力量，我们称之为领导层更迭。这种引导决定了该群体成为领导者并尝试逃跑的机会。领导力源自群体地位和群体偏心。如果一个生物在群体的前缘涂油，它就有更高的机会逃脱。逃离群体被模拟为一系列速度增加，这些速度增加被添加到物体的当前速度上。整个系统易于实现、高效，并且可以在标准计算机上以每秒 30 帧的速度运行数百个保持油的模拟。我们的系统旨在实时模拟，并有潜力用于游戏、人群模拟等。版权所有 (c) 2006 Joint Wiley & Sons, Ltd.。
Die classical work of bird-like objects of Reynolds simulates polarized motion of groups of oriented particles, bird-like objects, or simply boids. To do this, three steering vectors are introduced. Cohesion is the tendency of boids to stay in the center of the flock, alignment smoothes their velocities to similar values, and separation helps them to avoid mutual collisions. If no impetus is introduced the boids wander somewhat randomly so apt external leading force is necessary for the correct flock behavior. As call be observed during the bird flocking in the fall, birds sometimes move in a Way that is not captured by the above described framework. Some of the birds, typically the ones on the edge of the flock, suddenly shoot-off. The flock then pursues this leader. In the original Work by Reynolds the cohesion and separation are two complementary steers. We introduce a complementary force to the alignment that we call the change of leadership. This steer defines the chance of the boid to become a leader and try to escape. The leadership is derived from the boid position and the flock eccentricity. If a boid is oil the front edge of the flock it has a higher chance to escape. Escaping from the flock is simulated as a sequence of velocity increases that are added to the current velocity of the boid. The entire system is easy to implement, is efficient, and runs simulations of hundreds of holds oil a standard computer at 30 frames per second. Our system is aimed to real-time simulations and has the potential to be used in games, crowd simulations, etc. Copyright (c) 2006 Joint Wiley & Sons, Ltd.
