1999年，通过雷诺兹的持续研究，'''个人主义导航individualistic navigation'''开始了它在人群模拟领域的进程。仿真中，'''指导行为Steering Behaviors'''在自动化主体过程中起着重要的作用。雷诺兹指出，低水平运动的过程依赖中等水平的指导行为和高水平的目标状态以及'''路径寻找策略Path Finding Strategies'''。在 Reynolds、 Musse 和 Thalmann 工作的基础上，他们开始研究人群的实时模拟模型，以及它们在人类行为中的应用。对人群的控制被指定为一个具有不同主体自治水平的层级组织结构。这标志着在类似人的主体上，以最基本的形式建立个体行为模型的开始。

Coinciding with publications regarding human behavior models and simulations of group behaviors, Matt Anderson, Eric McDaniel, and Stephen Chenney's proposal of constraints on behavior gained popularity. The positioning of constraints on group animations was presented to be able to be done at any time within the simulation. This process of applying constraints to the behavioral model is undergone in a two-fold manner, by first determining the initial set of goal trajectories coinciding with the constraints, and then applying behavioral rules to these paths to select those which do not violate them.

马特 · 安德森、埃里克 · 麦克丹尼尔和史蒂芬 · 陈尼关于人类行为模型和群体行为模拟的论文发表后，行为约束的提议大受欢迎。对组动画的约束定位被提出能够在任何时候在模拟中完成。将约束应用到行为模型的过程分为两步: 首先确定与约束一致的初始目标轨迹集，然后将行为规则应用到这些路径上，选择那些没有违反约束的路径。

Correlating and building off of the findings proposed in his work with Musse, Thalmann, working alongside Bratislava Ulicny and Pablo de Heras Ciechomski, proposed a new model which allowed for interactive authoring of agents at the level of an individual, a group of agents and the entirety of a crowd. A brush metaphor is introduced to distribute, model and control crowd members in real-time with immediate feedback.
