Abstract: In crowd simulation, if all of the virtual characters look alike, it will appear to be
clones and lack reality as in real world. The paper studies the diversified appearance of characters
from aspect of models, textures, postures and so on. The paper realizes character model
differentiation by using Hasler model library, achieves diversification of the appearance by texture
templates, and obtains the various postures by skeleton embedding technology for the model. The
results show that the proposed method can generate plausible virtual crowd with good diversity.

Key words: crowd simulation, crowd diversity, characters model, characters texture, walking
