Parametric Design of Visual Simulation Based on Vega Prime

In order to improve the versatility of visual simulation and reduce the repeated development, a parametric design approach was proposed based on the development model of Vega Prime. The development framework of visual simulation based on Vega Prime was analyzed, and three key technologies of parametric modeling were studied: 1) simulation architecture design, to provide a unified design structure for parametric modeling; 2) parameter extraction and description, to standardize the design and implementation of parameters; 3) parameter constraint rules calculation, to associate model parameters, avoid the conflict between parameters and simplify parameter instantiation. Finally, an instance system of parametric visual simulation was designed and implemented. In this instance, the parametric modeling process was described, the visual effects were given, and the feasibility and validity of the parametric design approach were verified.
