“…Vega offers a variety of Volume types including Box, Sphere, Cylinder, Frustum, points, lines, polygons, and segments. The Z method, LOS method, ZPR method, and HAT method are composed of a vector segment, hence, they can only detect if there is a collision occurs on one direction [3,4]. Nonetheless, BUMP method consists of 6 perpendicular segments, all six segments extend along the X, Y, Z three axes in the direction of the positive and negative, which constitute a box.…”

“…A lot of researches on the modeling and driving of this visual simulation system for bridge cranes have been done in the past, but the rare collision detection technology studied leads to shortcomings such as through each other among virtual objects , not strong immersion in the visual simulation system developed. Therefore, the collision detection technology is applied combining with the collision requirements of hook and goods in the virtual simulation system for bridge cranes and based on the principle of collision detection provided by Vega in this paper [3]. The collisions between the hook and goods, hook and machine tools or other virtual objects in the scene are avoided according to set the collision between hook and virtual objects using intersection vector methods [4] provided by Vega.…”

Collision detection is the key technology in the visual simulation system for bridge cranes. According to analyse the collision between hook and virtual objects in visual simulation system for bridge cranes, collision detection method of visual simulation system for bridge cranes is determined based on the collision detection principle. First of all, LOS intersection vector method is chosen based on the principle of collision detection in Vega. Hook is designed for the collision target using Isector module in Lynx and the same intersection vector masks in Isector Class are guaranteed. Then, the BUMP collision detection for hook is created by calling vgIsector functions in VC++ and BUMP detection method of hook is bounded with hook. Finally, conditional statements which ensure hook to move without collision are compiled. Therefore, the virtual scene around the hook is detected in real time. The results show that the phenomenon of passing through by mistake for the hook can be avoided applying the BUMP collision detection method in Vega software in visual simulation system for bridge cranes, and the accuracy for BUMP method detecting the goods is improved using LOS collision detection method.
