Research and Implementation on the Three-Dimensional Modeling of Interior Building Component

To solve the existing problems of the interactive modeling of buildings, a fast, automatic and detailed modeling algorithm is introduced. Through customizing property library, drawing a plane figure of the building and building components, and configuring properties for them, the algorithm could automatically complete the whole modeling process. The three-dimensional model can be automatically modified with the property information of GIS. The algorithm is widely applied into LionKingSoft digital city system and meets the requirements of rapid modeling of the large group of buildings. The experiment results indicate the algorithm is rapid, accurate and practical.
