Basketball has grown into an international sport played and watched by millions of people. This paper describes the implementation of a virtual basketball accelerator. The main purpose of our study was to devise an application that could literary help players in practicing a free throw game indoors. In the development of this project we used Matlab, XVR and 3ds Max. The Matlab trajectory is simulated considering the development of a realistic behavior. The data acquisition from the trackers is adapted both for magnetic and optical markers, therefore extending its usability. The coordinates are then sent via UDP to the XVR environment, which draws the moving parts accordingly. The overall performance is improved by paying a great deal of attention to details.
