【摘要】：變形造型技術(shù)在現(xiàn)代科學(xué)技術(shù)的各個領(lǐng)域得到了廣泛的應(yīng)用。在機械行業(yè),特別是產(chǎn)品概念設(shè)計或是逆向工程中數(shù)據(jù)處理當(dāng)中,為了讓產(chǎn)品的外觀滿足人們的視覺效果,或者讓重構(gòu)的模型精度提高,通過添加各種約束使模型發(fā)生變化,達到理想的效果。本文通過研究基于能量法變形造型原理,ACIS造型組件變形模塊,HOOPS組件的渲染技術(shù)等,結(jié)合這些技術(shù)開發(fā)出了一套基于ACIS平臺的變形造型系統(tǒng),并應(yīng)用于逆向工程領(lǐng)域。 本文將ACIS幾何造型技術(shù)與HOOPS模型顯示技術(shù)相結(jié)合,給出了變形造型系統(tǒng)的功能,并討論了各功能模塊之間的聯(lián)系,同時對變形造型系統(tǒng)的建模功能模塊、變形功能模塊、顯示功能模塊做了詳細的功能設(shè)計。主要完成的工作和結(jié)論如下： 1)論述B樣條曲線曲面的基本性質(zhì)和基于能量優(yōu)化法曲線曲面變形的基本理論,介紹了ACIS、HOOPS及InterOp三大組件,為變形造型系統(tǒng)的開發(fā)提供了理論依據(jù)。 2)聯(lián)系逆向工程數(shù)據(jù)處理的實際情況,認真做了調(diào)研分析,提出了變形造型系統(tǒng)的功能架構(gòu),并定義了各功能模塊。 3)變形造型系統(tǒng)各功能模塊的開發(fā)。根據(jù)各功能模塊的設(shè)計要求,完成了各功能模塊的開發(fā)。 4)提出了SAT格式文件與STL文件相互轉(zhuǎn)化的方法,彌補了InterOp對常用格式文件轉(zhuǎn)化的不足。 5)在論文的最后一章,通過兩個實驗來驗證該變形系統(tǒng)實踐當(dāng)中的應(yīng)用。個是在逆向工程數(shù)據(jù)融合方面的應(yīng)用,另一個是產(chǎn)品的概念設(shè)計方面的應(yīng)用。
[Abstract]:Deformation modeling technology has been widely used in various fields of modern science and technology. In the mechanical industry, especially in product conceptual design or reverse engineering data processing, in order to make the appearance of the product meet the visual effect of people, or to improve the precision of the reconstructed model, the model changes by adding various constraints. Achieve the desired effect. In this paper, based on the principle of energy deformation modeling, the rendering technology of ACIS modeling module deformation module / hoops component is studied, and a set of deformation modeling system based on ACIS platform is developed, which is applied in reverse engineering field. This paper combines ACIS geometric modeling technology with HOOPS model display technology, gives the function of deformation modeling system, and discusses the relationship between each function module. At the same time, the modeling function module and deformation function module of deformation modeling system are discussed. The display function module has made the detailed function design. The main works and conclusions are as follows: 1) the basic properties of B-spline curve and surface and the basic theory of curve and surface deformation based on energy optimization method are discussed. It provides a theoretical basis for the development of the deformation modeling system. 2) in connection with the actual situation of reverse engineering data processing, the paper makes a careful investigation and analysis, and puts forward the functional framework of the deformation modeling system. Each function module is defined. 3) the development of each function module of deformation modeling system. According to the design requirements of each functional module, the development of each functional module is completed. 4) the method of converting SAT format file and STL file is put forward. 5) in the last chapter of the thesis, two experiments are carried out to verify the application of the deformable system in practice. One is the application of reverse engineering data fusion, the other is the application of product conceptual design.
