【摘要】：非真實感圖形繪制是近十年來計算機圖形學(xué)研究領(lǐng)域逐漸興起的學(xué)科,它的出現(xiàn)使得圖形的繪制更加有選擇化、個性化和藝術(shù)化,為圖形繪制提供了比以往更多樣的目標(biāo)和選擇,近年來非真實感圖形繪制技術(shù)得到迅速的發(fā)展。剪紙是我國歷史悠久的傳統(tǒng)民間藝術(shù)之一,因為它所使用的工具和材料簡單,應(yīng)用范圍很廣,是我國廣大群眾喜聞樂見的一種重要的民間藝術(shù)。剪紙藝術(shù)在刻畫藝術(shù)形象上也有自己的特點,這主要是由于它在制作條件上受到“剪”和“紙”的限制,只能通過鏤空而形成顏色對比和物體連接來刻畫形象,正是基于剪紙的以上特點,本文利用計算機來模擬生成剪紙圖樣,讓這一藝術(shù)形式能在計算機上得到重現(xiàn)。 首先分析了手工剪紙的特點,將其紋樣分成了四類:⑴基本結(jié)構(gòu)紋樣。基本結(jié)構(gòu)紋樣用于表示對象的形體特征,一般包括頭、軀干、四肢和尾巴四個部分,紋樣包括直線、圓和圓弧以及各種曲線等,使用這些紋樣,可以簡單地勾畫出動物的基本形象,包括一些夸張的頭的形象。⑵特征紋樣。特征紋樣用于反映其表現(xiàn)對象的特征,例如牛、羊等動物有角,而馬、鼠、鹿有尾等,對動物的不同特征,通過建立特征紋樣庫來實現(xiàn),并通過參數(shù)的變化以滿足不同的要求,如角、尾的長短等。⑶特定紋樣,獸畜類動物形象頭部的五官結(jié)構(gòu),一般都采用特定的紋樣。眉毛用(?)紋,眼睛用(?)紋或(?)紋等,鼻子用(?)紋或(?)紋,嘴巴用(?)紋或(?)紋等。⑷各種裝飾紋樣,裝飾紋樣反映了剪紙表現(xiàn)形式的程式化,將復(fù)雜的事物和變幻不定的自然景象條理化、具體化,體現(xiàn)出剪紙藝術(shù)的民族特點。 根據(jù)剪紙紋樣的特點,采用基于骨架的技術(shù)生成紋樣,即根據(jù)紋樣的結(jié)構(gòu)設(shè)計出對應(yīng)的線狀骨架,然后在骨架上生成相應(yīng)的形狀,通過控制骨架的大小、粗細(xì)、角度和彎曲程度就可以生成符合需要的紋樣,生成的各種紋樣最后組建為紋樣庫。 根據(jù)剪紙使用材質(zhì)的特性,圖案的對稱性成為剪紙的一個標(biāo)志性的特點。根據(jù)這一特點將生成紋樣的控制點分為位置約束點和形狀約束參數(shù),形狀約束參數(shù)是控制紋樣的形狀和大
[Abstract]:Non-realistic graphic rendering is a subject that has emerged gradually in the field of computer graphics research in the past ten years, and its appearance makes the drawing more selective, personalized and artistic. The technology of non-realistic rendering has been developed rapidly in recent years. Paper-cut is one of the traditional folk art with a long history in our country. Because of its simple tools and materials, paper-cut is a kind of important folk art that the masses of our country like to see. Paper-cut art also has its own characteristics in depicting artistic images. This is mainly because it is restricted by "cutting" and "paper" in production conditions, and can only be depicted by hollowed-out forms of color contrast and object connection. Based on the above characteristics of paper-cut, this paper uses the computer to simulate and generate the paper-cut pattern, so that the art form can be reproduced on the computer. Firstly, the characteristics of manual paper-cut are analyzed, and the patterns are divided into four categories: 1. Basic structural patterns are used to describe the physical characteristics of an object, generally including the head, trunk, limbs and tail, and the patterns include straight lines, circles and arcs, and various curves, using these patterns. The basic image of the animal can be simply outlined, including the image of some exaggerated head. Feature patterns are used to reflect the characteristics of their objects, such as cattle, sheep and other animals with horns, while horses, rats and deer have tails. Different features of animals are realized by establishing a feature pattern database, and by changing the parameters to meet different requirements. Such as the angle, tail length and other specific patterns, animal image head structure, generally used a specific pattern. Eyebrows) Stripe, eye) Stripes or scallops) Stripes, etc., with nose) Stripes or scallops) Stripes, mouth with a) Stripes or scallops) All kinds of decorative patterns such as grain, decorative patterns reflect the formulaic form of paper-cut, the complicated things and the changeable natural scene are organized and concretized, and the national characteristics of paper-cut art are embodied. According to the characteristics of paper-cut pattern, the technique based on skeleton is used to generate the pattern, that is, the corresponding linear skeleton is designed according to the structure of the pattern, and then the corresponding shape is generated on the skeleton. By controlling the size and thickness of the skeleton, Angle and bending degree can produce patterns that meet the needs, and all kinds of patterns can be constructed into pattern database. According to the characteristics of paper-cut material, the symmetry of patterns becomes an iconic feature of paper-cut. According to this feature, the control points that generate patterns are divided into position constraint points and shape constraint parameters, and shape constraint parameters are the shape and large shape of the pattern.
