Usually when scene when too much the introduction the editor computer may not come for calculation and caused part object unable to load the past, finally to obtain the scene model is not full, the model loss phenomenon, even if the computer with scene of all models are loading in its operation speed may also slowly, in order to avoid the happening of the above phenomenon solution is as far as possible will be the same material objects respectively pay good material, adjust their texture mapping and then will the material of the same object to merge, in order to reduce the number of scene model.
To achieve this purpose, the 3D model creation is finished, to model surface texture matching, its texture data is three dimensional city model indispensable part of three dimensional city model is an important part of the construction, to processes the good map texture of multi-dimensional son material and UVW texture mapping technology and model matching, complete 3D model create work.
Research area 3D model data results are provided eventually in 3DS and DXF format, after completion of study, and through the data format with different different platform of the geographic information system to provide 3D model experiment data, the use of verification, in the current domestic market has appeared a lot of geographic information digital platform and virtual reality environment platform, we are used for the market is used widely with the skyline Virtools platform test, data read in good condition, running smooth, verify the 3D production data science and rationality.

(4) When the market demands highly on pro-environmental protection products, module partition is usually focused on recycling, which helps to aggregate the polluted materials or recycled materials into a module to facilitate the recycling, processing, and thus realizes green production.
Every component can be used as a standalone product in the market to promote the professional and commercial production; (5) Expandability: With the development of technology, especially with emergence of new materials and new processing technology, the performance of components which are more stringent with material and process are inevitably and greatly improved.
This kind of components should be designed as a separate module to facilitate the efficient use of new technologies and new materials; (6) The Principles of Basic Parts: The function and structure of basic parts such as bed, column, etc. which are mostly cast or welded, are more independent.
