Hybrid Collision Detection Algorithm in Maintenance Simulation

An collision detection algorithm based on Axis Aligned Bounding Box(AABB) and geometrical restriction is proposed to solve the problems of collision between different objects in maintenance simulation.It adopts AABB to improve the effect of collision detection between the virtual human and others objects.Geometrical restriction algorithm is used to solve the problem of collision detection between the accessories belong to virtual human and the others.Collision detection algorithm combines the speediness of AABB and exactitude of geometrical restriction,and experimental results indicate that it makes real-time collision detection effective.
