The Post-Processing Technology of Finite Element Simulation Based on Direct3D

This paper mainly focuses on the simulation of sheet forming and resin transfer molding,designs and develops a FE post-processing system based on the theory of OOP and computer graphics.This application is designed to utilize MVC architecture,powered by Direct3D APIs and running on the.Net platform.The paper demonstrates the key technology regarding post-processing,including data interpolation processing,contour line generation,object selection,physical value display on the intersection plane,advanced scene rendering based on the HLSL language,backlight rendering techniques,and the deferred lighting technology,and evaluates the rendering performance.As the application is designed to be lean,fast,easy-to-use,and good visual quality,it satisfies the requirement of visualizing the result of the FE simulation well.
