초록
본 연구에서는 색연필로 그린 듯한 게임 렌더링을 위한 컬러 연필 텍스처를 생성하는 기법을 제안한다. 이를 위해서 흑백 연필 텍스처를 입력으로 받아 색의 삼원색인 청록색(cyan), 보라색(magenta), 노란색(yellow)의 연필 텍스처로변환한 다음, 이 텍스처들을 중첩하여 다양한 색상의 텍스처를 생성한다. 그리고 직관적인 텍스처의 사용을 위하여HSV(hue, saturation, value) 컬러 모델에 근거한 컬러 연필 텍스처 지도를 구성하는 방법을 제시한다. 기존에는 영상으로부터 입력받은 색을 그대로 사용하여 연필 효과를 내는 연구가 있었으나, 임의의 컬러 연필 텍스처를 만드는 방법을 시도한 연구는 없었다는 점에서 본 논문은 공헌이 있다. 그리고 실제 색연필로 색을 섞는 과정과 유사한 색의 표현을 가능하게 하는 새로운 단순화된 감산모델을 구현하고, 이를
Abstract
We present a technique for generating color pencil textures for rendering game scenes in a color pencil style. Our technique generates pencil textures of various colors by composing textures of cyan, magenta, and yellow, the three basic colors from CMY color model. In order to support intuitive color synthesis, we build a color pencil texture map that can be exploited by HSV color model. The main contribution of this paper is that we present an intuitive color pencil texture map that can be exploited by a game designer who needs to compose their own colors.
