| Abstract:Collision detection has important applications in visual simulation. A three-dimensional visual display and collision detection method is studied for deep space exploration dynamics simulation. The three-dimensional modeling software builds the simulation object and introduces it into matlab's virtual reality toolbox for dynamic display of the detector landing asteroid surface.The kinematic process of the OBB collision detection algorithm is improved and optimized to traverse the hierarchical structure to achieve the real-time requirements of deep space exploration collision detection， better implementation of collision detection between complex rigid body. |
