Abstract


Nowadays, the information technology is rapidly developed around the world. The information technology is becoming the driving force for promoting the development of human society. A profound change has effect on interior design industry in the information age. With the development of the computer, hand-drawing has been fully replaced by computer graphics, the working process of designer’s has also changed. The main purpose of this paper is to develop a fast three-dimensional modeling plug-in based on Sketchup platform. The fast-modeling plug-in can reduce the duplication of basic modeling for designers, output showcase three-dimensional model in very short time, greatly improve the efficiency of the designer’s work.First of all, this paper expounds what does three-dimension is and introduced the latest technical about three-dimensional modeling. Meanwhile, this paper also introduces a new computer-aided architectural design technique-BIM and the latest modeling software. Next,the paper introduced the implementation and type of the mainstream plug-in. By comparing BIM with traditional CAD technique, explains the BIM technology and his advantage in architecture area. After instructed some software which perfectly merge with BIM, choose Sketchup as the development platform. Though explaining the functions and features that Sketchup has, introduce the history and features of the develop language Ruby. After that , the paper focuses on explaining the software framework of the fast-modeling plug-in by dividing the framework into initial data acquisition, menu design and functional partitioning. This part explains how to develop the plug-in, the rule of the source program and how to load the plug-in in Sketchup. In addition, it explains how the plug-in get original data and the reason for choosing the method.Then, the paper explains how to implement the plug-in and practical application the plug-in by actual projects. Firstly, the paper explains this plug-in is secondary developed based on the Sketchup to meet the company’s business needs. Then, the paper comparing the old modeling flow with new modeling flow, have a conclusion which is this plug-in can not only reduce the work pressure of design department but also greatly accelerate the pace of the company project’s progress. After that, by defining varying parameter, design menu panel, building cabinet’s body, grouping, building cabinet’s doors, mapping basic material and building the top of cabinet, introduce the method of implementation and source code. By showing the showcase update project and the new production of showcase project, proved that after use this plug-in, the time that designer spend on modeling will have enormous differences.The last part of the paper is the conclusion and outlook of the plug-in. firstly, the paper explained this plug-in is developed base on Sketchup which can be mastered very quick by designers who don’t familiar with computer. Through the Sketchup Ruby API, use Ruby as the development language to have the second development base on Sketchup, finally successfully developed the fast modeling plug-in based on Sketchup. Then, the paper also pointed, there’s still some functions need to be developed in the future such as mapping material and lighting adjustment.
