dc.description.abstract在電腦圖學領域中,直接在人臉模型產生皮膚以及皺紋的材質是一件很有挑戰性的研究主題。我們提出一個有效率的方法將原來的人臉模型加以細分,以提高模型的網格密度,產生類似皮膚溝紋的模型。並用方程式模擬皮膚隆起的部分。最後利用Bump Mapping的技巧將皮膚產生出來。這個方法可以保留住皮膚表面的立體結構,避免將皮膚材質貼上人臉模型時遺漏的立體結構的缺點。我們也提出一個簡單的方法模擬額頭上的皺紋,及不同年齡層的皮膚膚質。最後將老化的皮膚與皺紋結合。zh_TW
dc.description.abstractIn computer graphics, synthesizing the skin textures on human face with wrinkles directly is one of the most challenging research topics. We propose an efficient method to subdivide patches of the human face model into smaller patches. Functions of barycentric coordinates are applied to simulate the curved ridges. Bump mapping technique is used to render skin surface on the human face model directly. This approach will hold the effect between the geometrical structure and the lights in the scene. We also propose a simple method to simulate the wrinkles on the face. Furthermore, the skin aging is synthesized by specifying a set of parameters and combing the skin surface model with wrinkles.en_US
