GRAPHIC VISUALIZATION ENGINE TECHNOLOGY OF LARGE-SCALE FINITE ELEMENT MODEL
摘要
Abstract
Aimed at the problem of weak visual interaction of large-scale finite element model in fine simulation analysis of complex structure,the key technology and software design scheme of efficient model data management and display are proposed.Based on the lightweight finite element model data structure design,an efficient finite element model data management engine was realized.Based on the minimum node correlation surface method,the internal unit surface of the mesh model was effectively eliminated,and the graphics rendering scale was reduced.The ray picking algorithm based on BVH structure and Qt communication mechanism realized the 3D model graphics interaction.A high-performance visualization engine SABRE.Visual was developed by using three-tier software architecture.Compared with software testing,it shows that the engine can fully support the display and interactive operation of finite element models with tens of millions of units/nodes,and has certain advantages in model display efficiency and applicability of large-scale problems.关键词
