Rendering and animating a large number of agents realistically, especially in real time, is challenging. To reduce the complexity of 3D rendering of large-scale crowds, techniques like culling (discarding unimportant objects), impostors(image-based rendering) and decreasing levels of detail have been used.<ref>{{cite journal |doi=10.1109/76.825720 |title=Real-time display of virtual humans: Levels of details and impostors |journal=IEEE Transactions on Circuits and Systems for Video Technology |volume=10 |issue=2 |pages=207–17 |year=2000 |last1=Aubel |first1=A. |last2=Boulic |first2=R. |last3=Thalmann |first3=D. }}</ref>

真实的人群中存在着外貌、体型大小、'''附件Accessories'''和（社会的或文化的）行为的差异，缺乏多样性的模型会影响视觉模拟的真实性。现有的系统可以创建具有不同纹理、大小、形状和运动画面的虚拟人群。
