Design And Implementation Of Physical Simulation System Based On Real-time Scene Modeling

With the rapid development of information technology,Computer Aided Instruction has been applied to many subjects,which effectively improve the teaching effect.Based on the current situation of many people having difficulty in learning physics because of physics has high demand for abstract thinking of learners.From the practice of physics teaching,the thesis analyzed and established functional requirements,as well as interactive demand.Finally,a physics process simulation system based on real-time scene modeling is designed and developed on the basis of Box2D and Qt for the development framework.The thesis divides the system function into four parts:system scene modeling,system scene management,system physical motion simulation and scene analysis.The detailed design and implementation of these four parts are discussed.System scene modeling allows to use the physical components provided by the system to model the physical scene freely according to their own needs.By using Json storage method combined with custom storage structure to realize the storage and import function of physical scenes.The system realizes the motion simulation of physical objects through the data transmission of physical calculation between Box2D and Qt.The scene analysis function 1s realized by analyzing the force and instantaneous state of the specified physical components.The system has certain application value in computer aided physics teaching with good interactivity and practicability.
