| Flow field visualization is one of the most challenging hotspots in visualization in scientific computing research,with a very wide range of development prospect and application area.This thesis mainly researshes and discusses the flow field data visualization methods of computational fluid dynamics.For the result data calculated by FDS(Fire Dynamics Simulator),this thesis improvements some algorithms of existing visualization techniques of scalar field and vector field by using the characteristics of OpenGL and GPU(Graphics Processing Units),and gives some corresponding examples which show that to some extent the speed and effect of visualization are improved.The improved algorithm can be used in flow field visualization,enhance the authenticity and analyzability of the flow field simulation.The research result has certain practical value. |
