Tree Paths: A New Model For Steering Behaviors

This paper describes a model for generating steering behaviors of groups of characters based on the biologically-motivated space colonization algorithm. This algorithm has been used in the past for generating leaf venation patterns and tree structures, simulating the competition for space between growing veins or branches. Adapted to character animation, this model is responsible for the motion control of characters providing robust and realistic group behaviors by adjusting just a few parameters. The main contributions are related with the robustness, flexibility and simplicity to control groups of characters. © 2009 Springer Berlin Heidelberg.5773 LNAI358371Reynolds, C.W., Flocks, herds and schools: A distributed behavioral model (1987) Proceedings of SIGGRAPH, pp. 25-34. , NY, USA, ppSachs, T., Polarity and the induction of organized vascular tissues (1969) Annals of Botany, 33 (2), pp. 263-275Tu, X., Terzopoulos, D., Artificial fishes: Physics, locomotion, perception, behavior (1994) Proceedings of SIGGRAPH, pp. 43-50. , NY, USA, ppLaValle, S., Rapidly-exploring random trees: A new tool for path planning (1998), Technical Report TR98-11, Dep. of Computer Science, Iowa State UniversityChoi, M.G., Lee, J., Shin, S.Y., Planning biped locomotion using motion capture data and probabilistic roadmaps (2003) ACM Trans.
