정물화는 회화에서부터 긴 역사를 두고 변천해 왔다. 17세기 네덜란드에서 성행하기 시작한 정물화는 일상적인 생활에서 만나는 사물을 회화적으로 재구성한 결과물이다. 눈에 보이는 사물을 그대로 그려 낼 수 있는 화가의 기량을 평가하는 기준으로 제시되었으며 인간의 생활상과 작가의 심상을 표현하는 하나의 장르로 자리잡았다. 또한 정물은 시대의 변화에 따라 그 소재가 다양해지면서 무한히 변화되었다. 특히, 현대사진에서의 정물사진은 대상이나 의미에 따라 그 시대의 일상적인 삶과 연관된 소재들이 다양해지면서 단순히 재현에만 머무르는 것이 아니라 사회를 반영하고 미학, 철학과 함께 구조적으로 변화됐다.

최근 비실사렌더링의 여러 가지 기술들이 발전하고 있다. 특히 회화적 느낌을 지닌 많은 연구들이 이루어지고 있으며, 그로 인해 2차원과 3차원 양쪽에서 여러 가지 방법을 통해서 좀더 스타일리스틱하며 아티스틱한 비실사렌더링이 연구되고 있다. 본 논문은 아티스트가 직접 그린 이미지에서 회화적 정보를 얻어와 스타일리스틱한 결과를 내는 새로운 방법을 제시한다. 본 논문에서 제시한 방법으로 이루어진 비실사렌더링의 결과는 단순히 모델이나 사진에 종속적인 색감에서 벋어나 아티스트가 원하는 색과 느낌을 가질 수 있게 된다. 그러므로 아티스트 개인의 예술적 표현을 비실사렌더링에 적용할 수 있게 된다.

An expression of image in visual communication design traditionally has a dose relationship with the mechanical part of several expression media. Especially, an image conversion becomes easter by converging various forms of image such as a pictorial expression, a drawing up a plan, an optical expression and a reflected image into digital data in the image expression using digital mode. In addition, synthesis between various forms of visual ,images is activated by the integration of all expression media into digital mode and thus the extent of the image expression becomes diversified. Moreover, there is a tendency that a various dimensional expression such as 3D and 4D is generalized in the image expression of digital design. A partial or whole image conversion has often occurred during the generalization process of several image forms. Such conversion summarized into two factors, a formative side and a technical side. We described the existing pictorial expression as a formative side, an optical expression as a photography, a materialization of image conversion theory of computer graphic image conversion according to data form as a technical side and specific content according to dimension. We summarized objective and demonstrative resets through a simple simulation using a computer for the contents required a technical and qualitative measure and presented an application program of the particular results from the study to the visual communication design work by a case.

본 논문에서는 회화적 렌더링에서 칼라변환을 이용한 브러쉬 스트로크의 생성에 관한 새로운 알고리즘을 제안한다. 본 논문의 브러쉬 스트로크 생성을 위한 전체적인 구성은 다음과 같다. 첫째, 두 장의 사진(한 장의 소스 이미지와 한 장의 참조 이미지)을 입력으로 하여 칼라 변환 이론을 적용하여 색상 테이블이 바뀐 새로운 이미지를 생성한다. 이 방법은 소스 이미지의 칼라 분포 형태를 창조 이미지의 칼라 분포 형태로 변환하기 위해, 선형 히스토그램 매칭이라 불리는, 간단한 통계학적 방법을 이용한다. 둘째, 가우시안 블러링과 소벨 필터를 이용하여 에지를 검출한다. 검출된 에지는 브러쉬 스트로크 렌더링 시 에지 부분에서 스트로크를 클리핑 함으로써 이미지의 윤곽선 보존을 위해 사용된다. 셋째, 브러쉬 스트로크의 방향을 결정하기 위한 방향맵을 생성한다. 방향맵은 입력 영상에 대한 영역 분할 및 병합을 토대로 만들어진다. 영역별 각 픽셀들에 대해 이미지 그래디언트에 기초한 일정한 방향을 부여함으로써 방향맵을 구성한다. 넷째, 구성된 방향맵을 참조하여 브러쉬 스트로크 생성의 기초가 되는 베지어 곡선(Bezier Curve)의 제어점(Control point)을 설정한다. 실제 회화작품에서 사용되는 브러쉬 스트로크는 일반적으로 곡선의 형태를 이루므로 곡선 표현이 가능한 베지어 곡선을 이용하여 브러쉬 스트로크를 표현하였다. 마지막으로, 생성된 브러쉬 스트로크를 에지부문에서 클리핑하고 배경색을 참조하여 블렌딩하거나 퐁 조명 모델을 이용하여 이미지에 적용하게 된다.

This study explores the characteristics and roles of non-textual elements in secondary mathematics textbooks in the United States and South Korea, using a conceptual framework that I have developed: variety, contextuality, and connectivity. Analyzing five U.S. standards-based textbooks and 13 Korean textbooks, this study shows that although non-textual elements in mathematics textbooks are free of literal language, they exhibit different emphases and reflect assumptions about what is important in learning mathematics and how it can be taught and learned in a particular societal context (Mishra, 1999; Zazkis & Gadowsky, 2001). While there are similar patterns in the use of different types of non-textual elements in textbooks from both countries, different opportunities are provided for students to learn mathematics between the two countries.

Present expression methods have close relations with popular culture in the active acceptance of various kinds of genre. Fashion illustration is no longer limited to sketching garments or technically explaining construction, it is accepted as an art that is expressed by the desire and consciousness of the artist. This study examines the expressional characteristics and effects of photo-image appropriation as an expression method in fashion illustration. The word 'appropriation' (to steal something) is used as euphemism and not meant to be derogatory. The methods of appropriation in art indicate that paintings are not inventions but are self-satisfactory creations that show that the idea of originality is false and that paintings should be uninhibited from the greed of the authority of the genius of artists. In postmodern paintings, the photo-image of appropriation are expressed through the methods of re-photography, photo collage, and photo painting. Photo-image appropriation methods in fashion illustration are re-photography, photo collage, image mixing of photography, drawing, and graphic expression of photography. Fashion illustrators are able to develop expression techniques for expanding a field of expression and enhance the ability of communication through the photo-image appropriation methods.

In the early twentieth century, history of animation began by modern artists, they produced various experimental images with the newly invented film and cameras. Artists in the field of movie, photography, paintings and others manipulated images in motion. But as some animated movies won industrial success and popularity, they became the trend but experimental style of early animation preserved by so-called non-mainstreamers or experimental animators, counteracting commercialism. Disney animation also followed the trend by applying realistic Hollywood film style, the worse critics placed a low value on the animation and it tarnished the image, although it was profitable investment from a business standpoint. To make images realistic, they opened a drawing class that animators developed skills to imitate motions and forms from subjects in real life. Also some techniques and gizmos were used to mimic and simulate three dimensional objects and spaces, multiplane camera and compositing 3D CG images with 2D drawings. Moreover, they brought animation stories from fairly tales or folk tales, and Walt's personal interest in live-action movies, they applied Hollywood-film-like narratives and realistic visual, and harsh criticism ensued. On the surface early disney animations' potential seems to be weakened, but in reality it still exists by simplifying and exaggerating forms and color as modern arts. Disney animation employs concepts of the modernism paintings such as simplified shapes and colors to a character design, when their characters are placed together in a scene, that visual elements cause mental reaction. This modification gives a new internal experience to audiences. As conceptual colors in abstract paintings make images appeared to be flat, coloring characters with no shading make them look flat and comparing to them, background images are also appeared to be flat. On top of that, multi-perspective at background images recalls modernist paintings. This essay goes in details with the animation pioneers' works and how Disney animation developed its techniques to emulate real life and analyses color schemes, forms, and spaces in Disney animation compared with modern artists' works, in that the visual language of Disney animation reminds of impression from abstract paintings in the beginning of the twentieth centuries.

A semiotic approach to modern visual arts has emerged since French post-structuralism was introduced to Anglo -American academics by "deconstruction" or "postmodernism." It views a work of art as a sign, which is its methodical assumption ana at the same time makes its application more accessible In the milieu of modern visual arts'effort to be intimate to with general audience, modern art photography is now faced with the request to be a familar and universal domain instead of being left only in photo books as artistic and academic achievements More specifically, various photo images 1mm such visual media as newspapers TVs, and computer graphics to such megaexhibitions as "Gwangju Biennale," "Media City Seoul," and "Pusan International Art Festival," are main objects of s030y. A coherent and scientific analysis of visual semitotics is still on the way; however, it is an urgent task how to read and interpret a photo image with multiple meanings This study argues that visual semiotics can be a powerful tool to enhance the understanding of art photography. After all, semiotics is a product of age; we live in the age of legibility, that is, of reading the work of art well as the social events and phenomena.rk of art well as the social events and phenomena.
