Based on vc and opengl software platform, as a part of integrate planar mechanism analysis and simulation cai, the mechanism theory has been adopted to analysis the movement trace and profile of linkage ; adopt oriented object method to capsulate the class module. each corresponding class module complete parameter storage and process ; adopt message - map, message - trigger to organize the programming and response the user " s input ; use the document - view structure of the visual vc + + mfc class foundation as the basis of the programming architecture to complete those functions. use oriented object method to product the following class module : control class, render class, document class, mechanism class and other classes ; adopt opengl library to draw the three dimensional graph based on the result of mechanism analysis ; use model transforming, lighting, material, color, frame - buffer, display - list, graphics - component combine etc to draw the three - dimension mechanism and make the simulation of linkage has high reality
