Forward Kinematics for Virtual Agents

Realistic motion and natural-looking simulations require a thorough understanding of hu- man movement control strategies. This work presents an initial developed on virtual agents. We describe how the agent was built searching an humanoid repre- sentation through a geometric model. Although this research is based on the work of Pettre et al. (16), we are building a solid platform to give total mobility and realism to both, the agent and the virtual en- vironment where our humanoid works. Preliminary results about forward kinematic applied to the actor are presented. This work allow us to keep on working on virtual agents area, to analyze and propose tech- niques to give the agent total autonomy to its motion.
