Description: SGI OpenGL is the company's new open-3D graphics software interface, applied to a wide range of computing environments, from the personal computer workstations, can achieve high-performance OpenGL 3D graphics capabilities. OpenGL itself not only provide simple graph yuan to the operation and control, but also provides many functions for complex object modeling. However, we usually prefer to use AutoCAD and 3DS max and tools to build models, and we have many such models, then how can we share resources and avoid duplication of work? CAD graphics standard data exchange format- DXF format, we can easily share resources, without the need to repeat modeling.
