Contour Optimization of Multi-channel 3D Chinese Ink Rendering Model

摘要: 3維水墨風(fēng)格模擬是非真實繪圖(NPR)的重要課題之一。傳統(tǒng)的渲染方法局限于黑白墨色，色彩單一。該文提出一種輪廓線優(yōu)化的多通道3維水墨渲染模型。首先，利用光照模型配合Alpha通道，完成3維水墨畫的內(nèi)部著色；其次，運(yùn)用網(wǎng)格模型擴(kuò)張實現(xiàn)輪廓線的風(fēng)格化；最后，利用表優(yōu)先級3維深度排序算法隱去Alpha通道中多余的輪廓線，實現(xiàn)3維水墨渲染圖像輸出。實驗結(jié)果表明，該方法渲染效果好，輪廓線優(yōu)化使水墨效果更加逼真，多通道的渲染圖像輸出也方便后期的圖像處理。

Abstract: The simulation of 3D Chinese ink painting style is an important research topic of the Non-Photorealistic Rendering (NPR). The traditional rendering methods are mostly confined to black and white ink. This paper puts forward a contour optimization of multi-channel 3D ink rendering model. Firstly, this method completes the inner coloring of multi-color ink by using the illumination model with the Alpha channel. Then it achieves contour stylization by means of the grid model expansion and texture map. Lastly, it hides the excess contours on the Alpha channel through the table priority algorithm of 3D depth sorting method for achieving the output of 3D Chinese ink rendering images. The experimental results demonstrate that the rendering effects under contour stylization provide more vivid ink effects. And the output of multi-channel images facilitates the following images procession as well. -
