| Fence is an essential part in road traffic safety, if it is available for testing and adjusting the guardrail crash performance on the computer, then it plays an important role in guiding the proper installation of guardrail in reality, and reduces the waste of resources, so realizing guardrail’s visualization by using3D emulation system is of great significance.This article has implemented guardrail’s three-dimensional simulation effectively by using OpenGL graphics interface and texture maps technology on the VC++development platform.The second chapter introduced the overall structure of guardrail for its visualization; The third chapter has analyzed the construction of some guardrail,such as f type concrete guardrail, overall f type concrete guardrail, Dan Po type concrete guardrail, overall type single slope type concrete guardrail and strengthened type concrete guardrail, and giving out how to do modeling and make visualization of guardrail; The fourth chapter has analyzed the constitution of waveform beam guardrail, and making modeling and visualization of the parts come true. The fifth chapter has analyzed the structure of cable barrier, followed by modeling, and visualization. |
