Three-dimensional Simulation on Collision Response of Ships
Abstract
In order to enhance the realism and fidelity of the navigation simulator in ship collision response simulation, a technical solution for adding the Bullet physics engine to the three-dimensional visual simulation of the navigation simulator is proposed. Using rigid body dynamics theory, collision dynamics and energy conservation law to establish a three-dimensional collision mechanics model of ships. In the collision response phase, the Gauss-Seidel iterative algorithm is used to solve the real-time six-degree-of-freedom position and attitude parameters of the ship during the collision process, and the rendering update is synchronized in the 3D view. Experiments show that the scheme is feasible, and it can render ship collision scenes in real time and stably, and the collision process conforms to objective physical laws, which effectively improves the realism and fidelity of ship collision simulation in navigation simulator.
