| Abstract: | 日本的動畫產業，尤其在亞洲地區，發展至今已成為一門廣為人知的產業，也不斷地產生出許多世界級的作品，在以往傳統製作方式中，總會需要畫師耗費大量工時進行作畫才能製作出一款動畫，而隨時著間推進，有越來越多的數位輔助軟體被整合進製作流程中，試圖加速製作進度以及為畫面添加更多特色。在近期，開始有動畫製作公司採用三維建模的方式來製作動畫，也開始有些動畫作品中的角色直接使用全三維建模的方式製作，但有別於傳統的二維作畫，全三維製作的角色在激烈打鬥或運動的場景中，除了在風格上與二維作畫有所差距，也無法很好地表現出二維作畫中的速度與力道感，導致一般觀眾在觀看上時不時的出現難以言喻的違和感。
本研究認為現今三維建模出來的角色在激烈運動時所造成的違和感，其原因為缺少了二維畫師在作畫時常會使用到的塗抹特效技術，因此我們透過幾何形變、邊緣成像，以及骨骼動畫的技術，讓這種日式動畫中的二維作畫特效也可以透過三維的方式成像出來。
The anime industry in Japan, especially in Asia, has developed into a well-known industry and has continuously produced many world-class works. In traditional production methods, animators would spend a lot of time drawing to create an animation, but with the advancements, more and more digital assistance software is integrated into the production process to try and speed up the production and add more features to the scene.
Recently, some animation production companies have started using 3D modeling to create animations, and some animation works have characters that are directly made using full 3D modeling. However, unlike traditional 2D animations, the full 3D characters in intense fight or action scenes not only differ in style from 2D animations, but also cannot effectively convey the speed and force feeling in 2D animations, leading to an indescribable sense of discomfort among the general audience when watching.
This research considers that the sense of discomfort caused by the intense motion of 3D-modeled characters today is due to the lack of smearing effect techniques that 2D animators often use when drawing. Therefore, through geometric deformation, edge rendering, and skeleton animation techniques, we can also display the 2D animation effects in Japanese animation in a 3D way. |
