Abstract: Exploded view has been widely applied in mechanical design and assembly practice, facilitating the understanding of the mechanical structure and assembly relationship visually. To solve the interference problem in simulation, this paper presents an automatic exploded view generation algorithm enhanced by collision detection. Firstly, according to the size and position deviation of the bounding boxes, the sequence and direction of explosion is calculated to conduct the initial separation. Secondly, based on the mutual exclusion properties of objects, the real-time collision detection is done to further separate exploded parts to enhance the exploded view effect with physics effects. The method is easy to implement, allows for reasonable movement between parts and avoids potential penetrations. The experiments have verified our method’s feasibility and universality.

Key words: exploded view, oriented bounding box, collision detection, spatial separation
