Abstract
In this paper, Dynamics Scene Graph Data structure (DSGD) is proposed, which is a strategy for the integration of a dynamic module and a visulization module. Open Dynamics Engine (ODE) is used as the dynamic module and Open Scene Graph (OSG) is used as the visulization module. DSGD is the high-level data structure combining two data structures of ODE and OSG. An algorithm to generate DSGD automatically is also studied. DSGD is applied to block erection simulation as one of the shipbuiding process simulation and the efficiency of DSGD is verified.
