Visualization Simulation in Scientific Computing is a new technique, it’s main idea is combine scientific computing of computer with 3D visualization simulation, the technique not only has the well accuracy and reliability of scientific computing of computer but also has very directly and reality display, it’s interaction is very well too. However, Visualization Simulation in Scientific Computing has some inevitably problem, the computing result of scientific computing of computer like finite element method is very complex and huge in data size, but simulation must be interactive and Real-time, the most important in Visualization Simulation in Scientific Computing is increasing efficiency of mass data display, reflect the valuable scientific computing of computer data lossless.The page Developed a power transmission tower design system in window system with vs03 and OSG, the main algorithm of the system are as follow, displaying the tower quickly with Flyweight design pattern, use lighting, shadow, material to enhance display effect, use texture to reflect data of mechanics.This system meet the need of mechanics of tower display, has good practicability and well extensional potential, what’s more, it can extension to wider range like simulation of sham battle, movie, Electronic entertainment and so on.
