Simulation of Baseball Pitching and Hitting on Virtual World

Simulating real world data in virtual world as like as in real world is important feature to support real sport practice in virtual world. In this paper, we describe how to simulate real world baseball data to support real batting practice in virtual world. The main idea is by applying several physics formula to generate pitch-ball trajectory and hit-ball trajectory in virtual world. We develop trajectory-generator in virtual world server which is based on those physics formula. Also in this paper, we explain several data that can be used for creating the baseball trajectory in virtual world.
