Application of Vega Path Tool in Visual Simulation System for Bridge Cranes

Aiming at the path sudden change and inconsistent turning of virtual vehicles in visual simulation system for bridge cranes, forklifts virtual paths are created by using path and navigator modules in Lynx interface based on the application principles of path and navigator in Vega software. Then, forklifts visual paths are edited to ensure the natural and fluent movements of forklifts by choosing spline navigator, setting smaller smoothing threshold and smaller spline tension parameters in Path Tool. Finally, combining working cycle requirements of loading and unloading goods for bridge cranes, continuous motions of several forklifts are realized by calling the path navigation library functions of Vega Software in VC++. Therefore, virtual vehicles complex paths are created and disadvantages of fixed path for virtual vehicles in visual simulation system are solved.
