Abstract


Visual simulation system of manipulating an important part of the simulator as a hovercraft hovercraft in the course of the campaign under the surface of the water and land-based virtual environment can be visually displayed in real-time, accurate collision detection technology to enhance the authenticity of the simulation environment and immersion plays a vital role . This paper analyzes the advantages and disadvantages of commonly used collision detection technology in the development process of the visual and the applicable conditions , be extended to meet the needs of hovercraft motion simulation system . For the collision detection hovercraft with static objects , eight used to calculate the intersection of the line of sight (LOS) vector construct by the outermost edge of the hovercraft , hovercraft simplified to achieve a rectangular box by collision , reaching fully detected static the purpose of the object from the visual effects and function sport hovercraft virtual environments more realistic and closer to the actual situation . For collision detection the hovercraft and dynamic objects , a two-stage , first initial collision detection algorithm using bounding ball early to rule out obviously not intersect objects on to reduce the amount of computation of collision detection ; Then, based on the axial the method of the bounding box of the bounding box (AABB) , the objects may intersect in more detail with collision detection. Preprocessing data structure depends on the collision detection , software development platform OpenGL Performer API bounding box in the modeling process , the establishment of the tree hierarchy of the model , the bounding box tree construction algorithm optimization , improved collision detection efficiency. Two simulation examples verify the algorithm is able to provide for the system in the case of to meet certain detection accuracy and efficient real-time collision detection results . Improve the realism of the virtual scene as a whole for hovercraft designed hovercraft movement trend in the marine environment and sea of three points of the match and terrain six matches in the terrestrial environment , real-time changes hovercraft pose of amphibians on the real-time movement , degrees. The final design of the turntable between the visual system and motion simulation hovercraft driving console . The experiments show that the collision detection method designed to meet the system requirements of real-time and accuracy .
