Computer Aided Design Simulation of 3D Garden Landscape Based on Virtual Reality

At present, landscape design teaching in design art education has received much attention. With the continuous development of social economy, science and technology and information network technology, traditional landscape design has also achieved a "quality" leap. The appropriate use of computer-aided software in landscape design has become an essential skill for landscape designers. Computer-aided software is like a pen in your hand, a tool that shows the designer's ideas and thinking. How to make students master computer-aided design software and use it reasonably in landscape design is a problem that current landscape design teachers need to think about and study. The existing CAD software for garden landscapes has limited expression of 3D models and virtual simulation effects, and can only be used for 2D construction drawing. In order to solve the dynamic landscape characteristics, a three-dimensional landscape design simulation system of virtual reality technology was developed. Object-oriented parametric 3D solid modeling method was used to realize 3D solid modeling, 3D real-time virtual rendering of design scenes, renderings and animations. Production, construction drawing and other functions, and explored the system computing principles, implementation methods and OpenGL extensions and other related technologies. Then the overall function of the system is briefly introduced, and the simulation process in the professional module is discussed in detail. Finally, the effectiveness of the system is verified by an engineering example.
