【摘要】：圖案在人們生活中無(wú)處不在。隨著科技的進(jìn)步和計(jì)算機(jī)圖形學(xué)的發(fā)展,圖案的繪制也開(kāi)始由傳統(tǒng)的手工設(shè)計(jì)方式向計(jì)算機(jī)輔助創(chuàng)作方式進(jìn)行轉(zhuǎn)變。目前利用計(jì)算機(jī)繪制圖案的方法主要分為三類:計(jì)算機(jī)輔助設(shè)計(jì)、基于數(shù)學(xué)模型自動(dòng)生成及基于知識(shí)庫(kù)的衍生設(shè)計(jì)。與傳統(tǒng)的手工繪制相比,這三種方式無(wú)論在生成效率,還是對(duì)圖案元素的復(fù)用方面都有了不同程度的改善。形狀文法是Stiny和Gips在1980年提出的,由一系列形狀和規(guī)則組成,通過(guò)帶標(biāo)記的形狀模擬和推理設(shè)計(jì)產(chǎn)生過(guò)程,從而產(chǎn)生新的形狀和設(shè)計(jì)方案。當(dāng)設(shè)計(jì)師預(yù)先設(shè)定了初始狀態(tài)和文法規(guī)則后,所有可能的設(shè)計(jì)方案都將包含在形狀文法的執(zhí)行過(guò)程中。將這一方法與衍生設(shè)計(jì)相結(jié)合,并由計(jì)算機(jī)實(shí)現(xiàn)文法規(guī)則的應(yīng)用,可極大擴(kuò)展設(shè)計(jì)的可能性,生成更加豐富的圖案。衍生設(shè)計(jì)是在圖案生成規(guī)則的基礎(chǔ)上,不斷的生成新的圖案。注重圖案生成過(guò)程的邏輯性,將有限的設(shè)計(jì)規(guī)則和設(shè)計(jì)約束發(fā)散衍生出大量圖案。衍生結(jié)果具有不可預(yù)知的特點(diǎn)。衍生設(shè)計(jì)已逐漸成為一種系統(tǒng)化的設(shè)計(jì)方法,被引入到建筑設(shè)計(jì)、藝術(shù)設(shè)計(jì)等各個(gè)不同領(lǐng)域中。本文主要針對(duì)二維圖案的風(fēng)格化衍生進(jìn)行研究,將形狀文法與衍生算法相結(jié)合分析圖案的生成規(guī)律,形成自動(dòng)生成算法。最后,通過(guò)Rhinoceros的Grasshopper,實(shí)現(xiàn)二維圖案的風(fēng)格化衍生。形狀文法確定圖案的生成規(guī)則和風(fēng)格,然后通過(guò)衍生算法不斷地生成新的圖案,且生成的圖案具有獨(dú)特的風(fēng)格特征。本文的主要工作包括:(1)對(duì)具有伊斯蘭風(fēng)格的幾何圖案進(jìn)行分析,得到伊斯蘭圖案的基本圖元。根據(jù)產(chǎn)生的基本圖元,采用形狀文法機(jī)制對(duì)風(fēng)格進(jìn)行解析和推理,產(chǎn)生圖案生成規(guī)則。(2)基于形狀文法的產(chǎn)生規(guī)則,本文提出兩種圖案漸變算法。在對(duì)二維圖案進(jìn)行變化的同時(shí)保持了圖案的風(fēng)格要素,產(chǎn)生風(fēng)格化的二維圖案變化。(3)基于衍生設(shè)計(jì)機(jī)制,針對(duì)伊斯蘭風(fēng)格圖案集(Leséléments de l'art arabe),綜合本文提出的兩種圖案漸變算法,配合圖案色彩賦值方案,使生成的圖案呈現(xiàn)出不同的視覺(jué)效果,生成具有伊斯蘭風(fēng)格的二維圖案。
[Abstract]:Patterns are everywhere in people's lives. With the progress of science and technology and the development of computer graphics, Pattern drawing has also begun to change from traditional manual design to computer-aided authoring. At present, the methods of drawing patterns by computer are mainly divided into three categories: computer-aided design. Automatic generation based on mathematical model and derivative design based on knowledge base. Compared with traditional manual rendering, these three methods are more efficient in generating, Shape grammars are proposed by Stiny and Gips in 1980, and are composed of a series of shapes and rules that are generated through marked shape simulation and reasoning design. When the designer sets the initial state and grammar rules in advance, all possible designs will be included in the execution of the shape grammar. And the application of grammar rules by computer can greatly expand the possibility of design and generate more abundant patterns. Derivative design is to generate new patterns on the basis of pattern generation rules and pay attention to the logic of pattern generation process. A large number of patterns are derived from the divergence of finite design rules and design constraints. The derived results are unpredictable. Derivative design has gradually become a systematic design method, which has been introduced into architectural design. In different fields, such as art design, this paper mainly studies the stylized derivation of two-dimensional pattern, combining shape grammar and derivative algorithm to analyze the pattern generation rules, and form an automatic generation algorithm. Through Rhinoceros's Grasshopper, we can realize the stylization derivation of two-dimensional patterns. Shape grammars determine the rules and styles of pattern generation, and then generate new patterns continuously through the derivation algorithm. The main work of this paper is to analyze the geometric patterns with Islamic style, and get the basic elements of the Islamic patterns. Based on the generation rules of shape grammar, this paper proposes two kinds of pattern gradient algorithms, which keep the style elements of the pattern while changing the two-dimensional pattern. Based on the derivative design mechanism, aiming at the Islamic style pattern set, Les 茅 l 茅 ments de LPU Arabe, this paper synthesizes the two pattern gradient algorithms proposed in this paper, which cooperate with the pattern color assignment scheme. The generated pattern presents different visual effects and creates a two-dimensional pattern with Islamic style.
