Abstract

The invention discloses a Modelica integrated three-dimensional scene simulation system; a Modelica multidisciplinary simulation interface module is connected with a Modelica multidisciplinary simulation module, processes and monitors Modelica simulation status signal and data output; a message queue module sets up message queues communicated with the Modelica simulation module and scene object motion control; a message scheduling module is used for ensuring the real-time property of the system; the scene object motion control module generates a motion control instruction of a three-dimensional simulation scene and needed motion parameters of a visual module; a three-dimensional simulation scene module sets up scene trees according to a lead geometry file; and the visual module conducts rendering through the scene image and effective commands by adopting three-dimensional scene simulation software. In the invention, the three-dimensional scene simulation and multidisciplinary simulation are organically integrated, so that a high-degree simulation environment based on physical behavior can be established.

Description

technical field [0001] The invention relates to a system in the technical field of system simulation, in particular to a multi-disciplinary physical law-oriented, three-dimensional visual simulation system. Background technique [0002] Visual Simulation is one of the most promising high-tech technologies in the 21st century. It is a combination of computer technology, graphic image technology, optical technology, control technology and other high-tech technologies. It is a science that performs three-dimensional modeling of the real world or the virtual world imagined by humans and drives it in real time, and displays it on a monitor or three-dimensional projection technology. Visual simulation is an immersive interactive environment based on computable information. Specifically, it uses modern high-tech with computer technology as the core to generate a realistic virtual environment with a specific range of visual, audio, and tactile integration. The necessary equipment i...
