中文摘要 | 本文敘述一可自動合成虛擬中國竹雕之電腦繪圖系統。本系統可以一全彩、灰階、或二元格式之中國水墨畫BMP圖形檔作為輸入,藉由所提出的轉換方法,將其轉換成所需之二元格式,再藉由所提出之瘦化(thinning)方法,將水墨畫中,筆觸的之軌跡及其寬度擷取出來。接著使用所擷取出來的參數來導引以隱含表面(implicit surfaces)所定義之虛擬鑿子來雕刻竹體以顯示出如浮雕與陰刻等不同風格之竹雕。竹體之雕刻面是以基於行進方塊(marching cubes)的方法來建構,竹稈中因垂直維管束所形成之特有紋理則是透過本文所提出之受限前緣(bounding front)機制來加以模擬合成。本系統已建構於一PC平臺上,藉由所提出之電腦繪圖系統,使用者可以在短短數秒內創作一件具備各種藝術風格之虛擬中國竹雕藝術品。由本系統之實際應用亦可充分驗證,本系統具有極高效能,並可產生極為逼真之各種竹雕作品。本系統可廣泛應用於輔助藝術家創作及家庭娛樂等用途上。 |
英文摘要 | In this paper we present a novel system-Virtual Bamboo Sculptor (VBS) to automatically synthesize the virtual Chinese bamboo sculpture. In our proposed system, we can take an image of Chinese ink painting either in true color BMP, gray scale BMP, or binary BMP file format as the input source. The input BMP file is then converted to desirable format of binary image by using our proposed conversion criteria. The skeleton and width of the strokes are extracted from the binary image of Chinese ink painting by using the proposed thinning algorithms base on two selected methods. The extracted parameters are then used to direct the virtual chisels defined by implicit surfaces to carve the bamboo volume model to show the art style of intaglio or relief bamboo sculpture. The carved surface in the bamboo volume model is constructed by a marching cubes based methods. The specific texture of the bamboo due to the special structure of the vertical vascular bundles in the bamboo culm is synthesized for the first time in the literature by using our proposed bounding from schemes. The synthesized bamboo texture is then applied effectively with the proposed solid texture based algorithm. We have implemented our proposed system on a PC platform. With our proposed system, the user can easily create an art piece of impressive virtual Chinese bamboo sculpture with various art styles within just a few seconds. The implementation of our system had shown to be quite efficient and the results of the synthesized virtual Chinese bamboo sculpture have shown to be quite convincing. |
