This application compiles and runs only on SGI machines running IRIX 6.5. The major files that are being used are main.C -- which interfaces with the C2, and performs the rendering of the tree, path, and also does the animation. RRT.C -- This is the base class for a holonomic and non holonomic RRT. The holonomic case (HRRT.C) is not being implemented here, but was used extensively while testing and in the initial stages. NHRRT.C -- This is the Non-Holonomic case of the RRT, and is specific to the problem It contains the algorithm to check for the result of firing each, a combo or no thrusters. It integrates the state equation, taking into account the peculiarities of the flow field to get the velocities and the final position every time a thruster configuration is fired. It takes in the obstacles and the start and destination point, as well as the flow field. Collision detection and boundary checks are also performed for each iteration.
