CG插畫介紹:
「CG」是計算機圖形Computer Graphics的縮寫。隨著以計算機為主要工具進行視覺設計和生產的一系列相關產業的形成,國際上習慣將利用計算機技術進行視覺設計和生產的領域通稱為CG。它既包括技術也包括藝術,幾乎囊括了當今電腦時代中所有的視覺藝術創作活動,如三維動畫、影視特效、平面設計、網頁設計、多媒體技術、印前設計、建築設計、工業造型設計等。
插圖畫家經常為圖形設計師繪製插圖或直接為雜誌、報紙等媒體配畫。他們一般是職業插圖畫家或自由藝術家,像攝影師一樣具有各自的表現題材和繪畫風格。對新形式、新工具的職業敏感和渴望,使他們中的很多人開始採用電腦圖形設計工具創作插圖。電腦圖形軟件功能使他們的創作才能得到了更大的發揮,無論簡潔還是繁複綿密,無論傳統媒介效果,如油畫、水彩、版畫風格還是數字圖形無窮無盡的新變化、新趣味,都可以更方便更快捷地完成。數字攝影是攝影的最新發展。攝影師用數字照相機拍攝對像或通過掃瞄儀將傳統的正片掃瞄進電腦,然後在電腦屏幕上調整、組合、創作新的視覺形象,最後通過膠片記錄儀輸出正片或負片。這種新的攝影技術完全改變了攝影的光學成像的創作概念,而以數字圖形處理為核心,又稱'不用暗房的攝影'。它模糊了攝影師、插圖畫家及圖形設計師之間的界限,現今只要有才能,完全可以在同一台電腦上完成這三種工作。
Computer illustration or digital illustration is the use of digital tools to produce images under the direct manipulation of the artist, usually through a pointing device such as a tablet or a mouse. It is distinguished from computer-generated art, which is produced by a computer using mathematical models created by the artist. It is also distinct from digital manipulation of photographs, in that it is an original construction "from scratch". (Photographic elements may be incorporated into such works, but they are not the primary basis or source for them.)
There are two main types of tools used for digital illustration: bitmapped and vector. With bitmapped tools, the content is stored digitally in fixed rows, columns, and layers, containing information about each pixel's hue, luminence, and sometimes filter settings. Popular examples include Photoshop, Paint Shop Pro, Corel Painter, and the GIMP. With vector-based tools, the content is stored digitally as resolution-independent mathematical formulae describing lines, shapes, and color gradients. Popular examples include Freehand, Illustrator, CorelDRAW, and Inkscape.
