Similar to my comments from last class, I enjoyed this "older" SIGGRAPH paper because it reads like a good textbook as opposed to a research paper. Anyways, the main issue I've always had with control based techniques is that while they ensure physical correctness, they do not necessarily look real (that is, like an actual human). The paper sort of steals my thunder on this by saying "... animals move with a smoothness and coordination that is not required by physical realism alone". Nevertheless, this paper is good in that it provides a good initial exploration into the successful use of applying control algorithms to generate balanced walking and running motions. I'm not quite sure I understand their allometric derivations of the scale factors in Table 1. Clearly, the dimension (not units!) of velocity are LT^{-1}, but why is its scale factor L^{1/2}? -- KenRose |

> > | (Animation of Dynamic Legged Locomotion) I strongly agree with the words that the control inputs are more like “suggestions” that must be reconciled with the dynamic state and structure of the system than “commands”. I feel very comfortable reading this paper since it provides the basic background of control system in which I don’t have much experience. FSM is very popular in game AI design and NPC control, and is simple to implement. While on the other hand, sometimes it will make the NPC act stupidly as the opponent of human player. So nowadays researchers and practitioners are trying to endow the NPCs with more intelligence so as to make the games more interesting.--Zhangbo Liu |
